May 2023 Issue of Design007 Magazine Available Now

As you’ll see in this month’s issue of Design007 Magazine, slash sheets such as IPC-4101/126 were never meant to be used by designers when comparing PCB laminates. These documents were created to facilitate communication between purchasing and customer service departments. You could say that slash sheets are made for administrative purposes, not engineering.

DownStream Discusses Rigid-flex and DFM Trends

I recently sat down with Joe Clark, founder, and Ray Fugitt, technical marketing manager, of DownStream Technologies to discuss trends in tool design and manufacturing, including rigid-flex design and refreshed graphical user interfaces (GUI).

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

In this week’s must-reads, we have coverage of NAMM 2023 and SMTA Atlanta, plus some tips for traditional PCB designers who are entering the RF design space, where designers have to master ideas like antenna tuning. We also have some news about March PCB sales, as well as a great conversation with Ventec’s Frank Lorentz, who explains how to set up an onboarding process that converts new hires into happy, long-term employees.

RF Antenna Design and Layout Tips for Your PCB

These days, it’s hard to think of a consumer product that doesn’t contain an antenna. Even my garage door opener can connect to my phone via Bluetooth or Wi-Fi. Each time a new RF antenna gets added to a PCB layout, it can create a new headache for RF designers, especially as analog design skills start to become critical again. With so many RF capabilities being added to new PCBs, how can designers ensure the signals in their system are not corrupted and signal integrity is preserved?

Simplifying Simulation and Analysis

Simulation has always been a critical step in the design process, and it’s only become more critical as design methodologies have become more complex. Gone are the days when simulation meant a simple logic simulation of your circuit, or a basic SPICE run to check signal waveforms. The simulation complexities that are required often fall “above the paygrade” of all but the most experienced members of a hardware design team. So how do you keep simulation from becoming a design bottleneck?

RF and Wireless Design Means Fighting Interference, Loss

Keysight EDA has been in the RF and microwave design industry for decades. We asked How-Siang Yap, product manager for Keysight EDA’s RF and microwave software tools, to share his thoughts on RF design tips and techniques, and how designing boards at RF speeds compares with designing PCBs at slower speeds. As he explains, much of RF design involves battling interference and loss.

Design for Cost in Real-time

When do you first start thinking about the selling price of your new product? It’s impossible to avoid the question of what the price will be. The worst answer is: “I don’t know, let’s see after the first samples.” Let’s say the product’s selling price is $49; then the manufacturing cost will be $20. During each design change, the manufacturing cost should be recalculated to make sure the product is still competitive. This means you should involve people from both the development and cost calculation teams. This circle will be repeated until the final design is released, and the final calculation is done.

NAMM 2023: It’s All About That Bass

The use of AI in the music industry seems only natural. For example, if you’re trying to create a specific sound, rhythm, mix of instruments, or volume level, you’d typically be in front of a series of mixers and controls, making tweaks and adjustments. If you’re trying to create a piece of music that is similar to one you already have, AI can do that for you. Just give it some basic instructions and let it go to work.

RF and Wireless PCB Design

RF is becoming almost ubiquitous; how many devices in your home contain at least one antenna? Automotive, aerospace, defense, and IoT segments are all pushing the envelope for wireless communication. But designing an RF PCB is a lot different than designing typical boards.

DFM Analysis for Flex and Rigid-flex Design, Part 1

Flex and rigid-flex PCB constructions are not new concepts. It has become commonplace as engineers look for alternative circuit packaging for ever-shrinking electronic products. A flat, one-sheet schematic for a straight ribbon cable is analogous to its physical flat substrate. A flat, multi-sheet schematic that details circuitry for a rigid-flex design bears little visual resemblance to its three-dimensional, variable material rigid-flex assembly. However, in both schematic examples, schematic-based analysis tools are applied equally. This same truth also applies to common FR-4-based two-layer or multilayer PCBs.

RF PCB Design: The Devil’s in the Details

Altium’s John Watson is a longtime designer and design instructor, not to mention a Design007 columnist. He’s been dealing with RF issues for years; his previous employer, Legrand, is one of the pioneers in smart lighting and data center solutions. John discusses the differences between designing RF and “typical” PCBs, how to avoid the missteps and miscues that can bedevil new RF designers, and why the tiniest details can make or break an RF design.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

How was your week? We’ve been pretty busy ourselves, bringing you coverage of the SMTA Expo & Tech Forum in Boise, Idaho. Tabletops shows like this offer a great value during the spring, in between the bigger shows like IPC APEX EXPO and SMTA International. In fact, SMTA schedules approximately 30 regional shows around the United States and abroad.

DFM 101: Final Finish Design Guidelines

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. There are many design considerations that need to be factored into any decision of which final finish to select for a particular application. We will cover these in this final installment of final finish DFM. Understanding the cost drivers in PCB fabrication and early engagement between the designer and the fabricator are crucial elements that lead to cost-effective design success.

Better Engineering Through Artificial Intelligence

At DesignCon 2023, I spoke with Cadence Design Systems’ Brad Griffin about artificial intelligence and machine learning as engineering aids for signal and power integrity optimization. Brad makes the case that artificial intelligence methods, when added to optimizing tools in the design flow, can help engineers to evaluate a larger number of potential solutions, and zero in on more highly optimized solutions than they may have found on their own.

IPC Design Competition Wrap-up

The IPC Design Competition took place during IPC APEX EXPO 2023, with five finalists competing—a far cry from the original 49 entries last fall. After the competition was over, we spoke with Kris Moyer, the IPC instructor who created the design used in the competition and served as a design advisor and judge for the event. We asked Kris to give us a quick wrap-up of the competition, as well as his thoughts on this year’s design, which none of the finalists completed.

Embedding Know-how Into Automation

Michael Ford, senior director of emerging industry strategy for Aegis Software, speaks with Barry Matties on the topic of tribal knowledge, its pros and cons, and its role in our industry.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Texans like to say that everything is bigger in Texas. That certainly seems to be the case for the SMTA Dallas Expo & Tech Forum. Publisher Barry Matties and I attended SMTA Dallas on Tuesday, and the tabletop show has now grown to 100 exhibitors, up from 92 vendors last year. It’s become more than a local or regional show, with some exhibitors flying in from Silicon Valley and the East Coast.

Material Matters and Tribal Knowledge

At a recent IPC Laminate/Prepreg Materials Subcommittee meeting, I made two observations: It was very well-chaired and managed, and despite a full attendance of very knowledgeable materials experts, none could remember the rationale for several of the specification sheet descriptions—slash sheets—that comprise IPC-4101E, “Specification for Base Materials for Rigid and Multilayer Printed Boards.”

Tips and Tricks in Today’s Designs

Filbert Arzola of Raytheon Intelligence & Space taught a Professional Development course at IPC APEX EXPO on general design practices. During a break, Filbert spoke with Kelly Dack about some of today’s design strategies and how designers are reacting to them. What matters most?

True Experts Can Cite Their Sources

We’ve heard a lot lately about the need to identify tribal knowledge within our organizations. How do you know whether an “expert” is sharing documented knowledge or it’s just something they learned at their first job during the Carter administration? We asked IPC design instructor Kris Moyer to explain his process for separating the wheat from the chaff, so to speak, in design knowledge. As he points out, a true expert will not be afraid to cite the sources and data sets behind their arguments.

Optimizing Communication Between Fabricators and Designers

During DesignCon, I spoke with James Hofer from Accurate Circuit Engineering about some of his customers' biggest challenges. We discussed various ways to increase the level—and quality—of communication between designers and fabricators. James also offered some interesting observations about bridging the gap between designer and fabricator. How often do you communicate with your fabricator?

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The captive shop used to be the rule, not the exception. Until outsourcing caught on, that is. North American captive shops went the way of the dodo bird, and the PCB market hasn’t been the same since. Even R&D went out the window, or offshore, if you want to be technical about it. But Schweitzer Engineering Laboratories (SEL) is something of a wild card. The company recently opened a new captive facility in Idaho, and the industry is paying close attention.

We asked Adam to share his thoughts on the competition, what it means to be one of the winners, and any ideas about improving the contest for 2024 in Anaheim.

ICT Seminar 2023 Review: Energy, Thermals, and Assistive Technology

Widely believed to be the traditional Centre of England, Meriden was a popular venue for a gathering of the UK printed circuit community this month. They braved the forecast of heavy snow for the Institute of Circuit Technology’s annual general meeting to learn about current developments and challenges in a thought-provoking technical seminar and to network with industry peers and contemporaries. Thankfully, the forecasted heavy snowfall did not reach Meriden until after the event; we only had a few flurries, although the weather caused considerable disruption elsewhere in the country.

Six Money-saving Material Properties When Designing PCB Stackups

Stackup decisions are critical to every PCB and electronic product, but they don’t always get the attention they deserve. With better stackup planning focusing on six key parameters, designers can select the best materials early in the design process and minimize the risk of under- and overdesigning their PCB.

IPC APEX EXPO 2023 Special Session: Advanced Packaging

The IPC APEX EXPO Special Session on Advanced Packaging this year attracted enormous interest, with Conference Room 2 at capacity long before the session began. Even with lots of extra seats squeezed around the edges, the session was standing room only for the just-in-time arrivals. IPC Chief Technology Officer Matt Kelly opened proceedings by introducing a distinguished panel of experts: Jan Vardaman, president and founder of TechSearch International; Sam Salama, CEO of Hyperion Technology; Matt Neely, director of process engineering at TTM Technologies; and Jim Fuller, VP of engineering technology at Sanmina.

With Tribal Knowledge, Trust but Verify

Patty Goldman recently spoke with Thomas about what this award mean to him

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

I try to not talk about the weather in this space, but this week I feel compelled. I’m based in the Pacific Northwest, and we’re relatively used to it being wet and rainy. But just south of us in California, the state has gone from what I read has been called the driest period in the West in the past 1,200 years to a right proper drenching. This week’s news cycle felt like one of those California-style “atmospheric rivers.” There was so much worthy reporting worthy that I was a bit overwhelmed in making my final selections. Suffice it to say that, this week, there is quite a bit of news that’s worth your time to read.

Shrinking Silicon, Growing Signal Integrity Challenges

What happens when die sizes shrink? As IPC design instructor Kris Moyer explains, quite a bit. Shrinking silicon can mean rising signal speed and rise times, and traditional PCB designers may find themselves dealing with problems formerly only seen by RF engineers. We asked Kris to discuss the pros and cons of silicon shrinkage and some of the techniques and trade-offs that PCB designers and design engineers need to understand as they find themselves entering the RF arena.

DFM 101: Final Finishes—OSP

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. The next final finishes to discuss in this series is OSP. As with all surface finishes there are pros and cons with the decision of which to use. It is a combination of application, cost, and the properties of the finish. OSP is RoHS-compliant as there is zero lead content in the finish.

Are You Offering Options in Your Bill of Materials?

In this interview, Saline Lectronics (an Emerald EMS company) President Jason Sciberras talks about PCB designers offering packaging options in the bill of materials. As Jason explains, mil/aero manufacturers like Saline can’t make many changes to a design without getting recertified, so including approved packaging options in the BOM from the start is a great way to go. Are you offering options in your BOM?

Meet Henry Crandall: New IPC Student Board Member

Barry Matties sits down with Henry Crandall, the newly minted Student Board Member on the IPC Board of Directors, to talk about how Henry became the first PhD student in electrical engineering in his family, as well as how his role on the IPC Board will allow him to represent the voices of students and young professionals interested in shaping the future of both IPC and the industry.

A Week-long Industry Extravaganza

We were back in San Diego, maybe for a “long vacation,” as IPC APEX EXPO is in Anaheim next year. Before we get to Anaheim, though, let’s talk about the show: It was a great week. I spent Sunday and Monday visiting some excellent Professional Development courses. As you know, this is a fast-changing industry, and we have to keep learning to stay ahead. On Monday, I attended the Microvia Weak Interface/Reliability subcommittee, and on Tuesday, the Ultra-HDI Technology Committee.

A First Look at IPC-CFX Box for Legacy Equipment

Although the prevalence of IPC-CFX in the electronics manufacturing industry has increased since the standard’s launch in spring 2019, the committee responsible for the standard has recognized legacy equipment in the field as a significant barrier to widespread industry adoption. To address this, an A-Team under the IPC-CFX Standard Task Group spent the past year working on a project that provides simple, readily available IPC-CFX hardware with supporting SDK that can act as an IPC-CFX endpoint for existing legacy equipment.

Alpha Takes the Greenfield Route

Alpha Circuit is a PCB fabricator located in Elmhurst, Illinois. Given that the launch of a new PCB fab is a rare occasion these days, we caught up with the senior team—Prashant Patel, president and CEO; Steve Smith, general manager; Steve Ryan, sales and direct support—guiding the buildout of Alpha Circuit’s brand new 44,000 square foot facility. They discuss what goes into equipment selection and line design, and the timing couldn’t have been better. At press time, the new facility was on schedule for test production by the end of January 2023.

A Post-show Marketing Plan

After you’ve exhibited at a trade show, then the work really begins. Where do you begin? How do you best capitalize on the leads and other contacts you’ve made? We asked Kiki Shimomae, sales and marketing coordinator for Taiyo, to discuss her pre- and post-show plans for a show like IPC APEX EXPO, and the importance of staying visible on social media.

PCB Designers Are Really Product Designers

As I look back on 2022, I’m realizing that my company plays multiple roles in client projects beyond just designing circuits and PCBs. Sure, we’re primarily a PCB design company, but we also help with things that happen outside the PCB. This includes tasks like enclosure design, defining mechanical constraints, simulating electrical behavior, mating boards into larger assemblies, selecting cabling, and defining test requirements, all of which slowly creep into the standard scope of work for design projects.

Real Time with... IPC APEX EXPO 2023: Automotive Electrification

Nolan Johnson talks with Senior Product Manager Chris Nash of Indium Corporation, who discusses Durafuse LT, a novel solder paste mixed alloy system with highly versatile characteristics that enable energy savings, high-reliability, low-temperature, step soldering, and assemblies with large temperature gradients. It also provides superior drop shock performance to conventional low-temperature solders, outclassing BiSn or BiSnAg alloys, and performing better than SAC305 with optimum process setup.

Real Time with... IPC APEX EXPO 2023: EMS Leadership Discussion

Guest editor Geoff Leeds meets with John Vaughan of Summit Interconnect to discuss his participation representing the PCB industry on the supply chain panel at the EMS Leadership Summit and the DoD roundtable, as well as trends he’s seeing in those market segments.

I-Connect007 Editor’s Choice: Five Must-Reads For the Week

It’s Feb. 3, 2023—2/3/23—and now we know the results of yesterday’s Groundhog weather forecast straight from Gobbler’s Knob in Pennsylvania. Punxsutawney Phil says six more weeks of winter. If you’re watching the ongoing ice storms blanketing much of the United States at present, that seems like a safe bet. Also a safe bet is that the most-read news this week is IPC APEX EXPO related. Additionally, this week IPC published its EMS and PCB numbers for December. All told, lots of industry news to read this week.

Real Time with... IPC APEX EXPO 2023: Wise Continues Expansion With Technica Partnership

Andy Shaughnessy sits down with Massimo Passerini, founder of Wise, and Technica's Jason Perry, to discuss Wise's latest PCB manufacturing automation. They also focus on the company's distributor partnership with Technica, which is moving into the PCB fab market. If you were unable to attend IPC APEX EXPO 2023, don't worry. We're bringing you coverage of the week's events in San Diego, from ribbon cutting to teardown.

DesignCon 2023 Opens With Strong Attendance

As George Costanza would say, “DesignCon is back, baby!” The show opened Wednesday morning, and it really felt like old times again. The aisles of the Santa Clara Convention Center were busy, and the classrooms for the technical conference were nearly full. And I spoke—or tried to speak—with quite a few engineers who spoke almost no English. That’s a good sign; in recent years, there were very few attendees from outside the U.S. because of Covid restrictions. The Pacific Rim is well represented this year.

Don't Blink: The IPC APEX EXPO Time-lapse

It’s a tradition here at I-Connect007 to set up a time-lapse for IPC APEX EXPO. There’s something satisfying, mesmerizing even, to watch the show floor build out and see the moment when the doors open and visitors fill the exhibit hall. Based on what others have said over the years, I know I’m not the only one whose favorite part is when the carpet gets rolled out and the whole character of the exhibition changes. This time lapse starts on the Saturday prior and continues through the Thursday tear-down phase.

DFM 101: Final Finishes—Electrolytic Nickel/Gold

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability.

IPC APEX EXPO Wrap-up

IPC APEX EXPO 2023 is over, and I think it was a successful show no matter how you slice it. There was barely a break in traffic on the show floor on Tuesday and Wednesday, and even on Thursday I saw people sprinting to close one more deal. Some committee meetings had nearly 200 participants; the meetings I sat in on were anything but boring.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week, the IPC APEX EXPO event has cast a long shadow across the news feeds. No, that’s not the right metaphor. No, not a shadow; shadows are dark. It would be more accurate to say IPC APEX EXPO cast a beam of illumination upon the news feeds for the electronics manufacturing industry. To that end, the APEX EXPO news makes a prominent appearance in this week’s editor’s picks.

Advanced Packaging Means Advanced Routing Issues

In today’s ever-shrinking world of electronics designs, the use of BGA parts with very fine pitch features is becoming more prevalent. As these fine-pitch BGAs continue to increase in complexity and user I/O (number of balls), the difficulty of finding escape routes and fan-out patterns increases. Additionally, with the shrinking of silicon geometry leading to both smaller channel length and increased signal integrity issues, some of the traditional BGA escape routing techniques will require a revisit and/or adjustment to allow for not only successful fan-out, but also successful functioning of the circuitry of the BGA design.

Scaling Beyond Silicon

Technology has always invoked radical changes, but unlike today, there used to be one major revolutionizing technology trend at a time. The world is becoming increasingly connected, more automated and more intelligent, driven by generational drivers—hyperscale computing, 5G, artificial intelligence and machine learning (AI/ML), industrial IoT (IIoT), and autonomous vehicles—which are invoking disruptive technological forces on vertical markets, unfolding varied levels of microelectronics and digital transformation across the globe. The increasing demand for miniaturization and higher speed is changing the dynamics of the semiconductor components needed to store and process data.

Bright Lights, Big City: STEM Event Kicks Off

The San Diego sun was warm and bright on Wednesday afternoon, but it didn’t stop the crowds from filling the aisles at IPC APEX EXPO 2023 for the trade show’s second official day. Technical conferences, professional development courses, and a keynote from IPC President and CEO John W. Mitchell kept attendees busy. But the real highlight of the day was upstairs where approximately 300 high school students from the local San Diego area rode buses to the San Diego Convention Center for a day full of activities meant especially for them.

IPC APEX EXPO 2023: Face-to-Face Not Mask-to-Mask

It was a bright, sunny California day as IPC APEX EXPO officially opened its doors on Tuesday, Jan. 24 at the San Diego Convention Center. The Technical Conference began on the same day, while the program of standards meetings and professional development courses had been in progress since Saturday, Jan. 21. During the hustle and bustle of the show build-up over the weekend, it was clear to see that so many exhibitors had the confidence to bring so much major equipment and to invest in such spectacular booths to display it.

A Challenge Facing Aerospace Designers In 2023

As the aerospace industry has been tasked with fitting increasingly complex electronics in existing airframes the demands on PCB substrates have begun to overtask the existing state of the art in PCB fabrication. Recently, I was called in to troubleshoot some reliability problems with a very dense PCB that had components on both sides and required the use of stacked blind vias and buried vias. The usual name for this kind of design is “build-up fabrication,” requiring many trips through the lamination, drilling, and plating operations at a fabricator.

Monday Recap: Optimism and Economics at IPC APEX EXPO

It was a packed house for two large events at IPC APEX EXPO 2023 on Monday, Jan. 23, as the EMS Leadership Summit was wrapped in the pale veil of caution, meanwhile hundreds more gathered to hear from IPC’s chief economist, Shawn DuBravac. At the EMS summit, the morning presenters from IPC all shared silver linings they saw inside the fading clouds of uncertainty.

It’s Here: The Launch of IPC Community Magazine

IPC Community Magazine launches today at IPC APEX EXPO 2023, both in digital and print form. It is now widely available for download at no cost. This magazine helps tell the stories of IPC, particularly for IPC members who use and interact with the trade organization. IPC worked closely with I-Connect007 (IPC Publishing Group) to develop the concept for the publication, and asked John W. Mitchell, president and CEO of IPC, to share a few thoughts as he looked at the magazine for the first time in print.

Classes and Meetings Under Way at IPC APEX EXPO

IPC APEX EXPO 2023 doesn’t officially kick off until Tuesday, but there’s plenty of action going on here at the San Diego Convention Center. Booths are sprouting up on the show floor, and exhibitors are starting to arrive. Upstairs, committee meetings have been taking place all weekend; the IPC-J-STD-001 and IPC-A-610 Joint Task Group, and IPC-A-600 and IPC-6012 Joint Task Group meetings, were abuzz with activity. The Professional Development classes began on Sunday, covering everything from design through assembly processes, flex and rigid-flex, and technologies of the future.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

We’re in the middle of show season, and it certainly “shows.” Thank you very much. I’m here all week. Don’t forget to tip your wait staff. This week, we published a variety of articles, columns, and news items, and much of it centered on trade shows. Technical Editor Dan Feinberg brings us a report from CES 2023. IPC announced the winners of the Best Technical Paper awards for IPC APEX EXPO 2023. And we have an interview with Altium’s Rea Callender about the company’s educational efforts at APEX and around the globe.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

“New year, new you.” That tagline seems to be everywhere right now. All five must-reads this week reflect this theme. Does this apply to you and your company? We have quite a duke’s mixture of articles. We’ve got AT&S outlining their market position on advanced packaging, and Auburn University doing research on smart manufacturing processes. Keysight is coordinating practical 6G research in Europe, Technica shares where they see the market growing, and SEMI adds new members to a key board responsible for market guidance. These five stories drew a lot of reader attention this week.

The Battle of the Boards

Last year, IPC held its first-ever design competition at IPC APEX EXPO in San Diego. PCB designers from around the world competed in a series of heats during the months before the show, culminating in a showdown on the show floor between the top three finalists. Rafal Przeslawski, now with AMD, took home the top prize last year. This year, the competition is back for its sophomore year. I asked Patrick Crawford, manager of design standards and related programs for IPC, to “layout” the details on the design contest, including lessons learned in 2022 and what’s new for the 2023 competition.

Shawn Dubravac: What’s New in Tech

As the world grapples with issues like climate change, consumers and manufacturers are increasingly looking for ways to reduce environmental impact. This has led to a focus on fostering innovation in sustainable materials, renewable energy sources, and recyclable components. One example is CarbonX, a new carbon material composed of nano-sized carbon filaments that could help tire makers meet the increasing demand for sustainability. Technology will play a pivotal role in this transformation and one sector set to see tremendous change is the auto industry.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The youngsters are back in school, and we’re all back to work. The water is back on for most of us in Atlanta; when temps dropped down to 8 degrees Fahrenheit, our pipes started bursting left and right. After a Christmas dinner with no water, I have a new appreciation for H2O. It’s been a busy week, and we published a variety of articles, columns, and news items. In this week’s top five, we have news about the market in Southeast Asia, a look at what the CHIPS Act really entails, a deep dive into CMMC, and a peek at how printed electronics developers are using flexible circuit concepts to facilitate PEC. We also say goodbye to a Top Gun PCB designer who left us way too soon.

ICAPE: Solutions With No Limits

Over the past five years, ICAPE Group has strongly focused on analyzing the complex needs of the market to provide worldwide solutions for customers whose needs range from simple to very complex technologies. The services provider has done this by putting offices in key strategic locations—particularly China—with staff that understand the nuances of language and culture. These types of decisions make an important difference when it comes to getting customers exactly what, and when, they need it. Yann Duigou, CMO, and Bingling Li Sellam, VP of Northern Europe, share their secrets for success.

Where Exactly is the Signal?

When I first got involved in printed circuit board design in the early 1990s, fast rise/fall times were just starting to become an issue. Prior to that we had been pretty much a “connect-the-dots” kind of technology. But as rise times got faster, it became necessary to worry about (electromagnetic) fields. One manifestation of that was EMI, and the increasing need to pass FTC compliance testing.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

Just because it’s a holiday week doesn’t mean the news is slow. Okay, maybe a little bit slower than normal, but “slower” can also be the same as “fast, just less fast.” We’re going a bit deeper into the list for our must-reads looking for high-impact hard news. I mean, you’ve all read the curated stuff already, no sense rehashing that. In fact, I’ll even throw in a bonus news item just because there was some good stuff this week. Have a great New Year’s weekend.

'Happy New Year' Celebrations Around the World

New Year’s Eve is tomorrow, and 2023 is around the corner. Where did the time go? That’s the $64,000 question. We celebrate New Year’s Day, in part, to help us mark the passage of time—sort of a shared experience for the human race. Humans have been celebrating New Year’s Day for thousands of years, but the party really took off in 45 BC, after Julius Caesar revamped the Roman calendar. From that point until the middle of the 18th century, New Year’s Day in Europe fell on a variety of days, including Dec. 25, March 1, and March 25. Andy Shaughnessy gives us the details.

Happy Holden on Gerry Partida’s ‘Significant’ Microvia Reliabilty Paper

Gerry Partida, vice president of technology at Summit Interconnect, authored a technical paper, “Next Progression in Microvia Reliability Validation—Reflow Simulation of a PCB Design Attributes and Material Structural Properties During the PCB Design Process,” at IPC APEX EXPO 2022, and it’s worth revisiting. This significant paper on microvia reliability validation provides a summary of what’s been happening in the microvia fabrication arena, especially regarding the issue of latent defects in stacked microvias.

DFM 101: Final Finishes ImmSn

One of the biggest challenges facing PCB designers is understanding the many cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability.

A Sneak Peak with Jim van den Hogen

Jim van den Hogen has been teaching PCB designers and design engineers about fabrication processes for decades. Twenty years ago, I had the opportunity to see a class of his at PCB West; even back then, the room was jammed with designers eager to learn more about DFM techniques. Now Jim is bringing his teaching expertise to IPC APEX EXPO 2023 this January with a similar class directed at PCB designers. I asked Jim to give us a sneak peek into his curriculum and to share what he hopes attendees will take away from his class, as well as his thoughts on how to best bridge the gap between design and fabrication.

Designing a Sustainable Future

While it may be traditionally considered a PCB fab and assembly show, IPC APEX EXPO is quickly becoming a destination for PCB designers and design engineers. Flipping through this year’s schedule, I counted 15 Professional Development and Technical Conference classes that focus on PCB design, as well as several fabrication classes that many of you should probably take. I checked in with Carlos Plaza, IPC’s senior director of educational development, to discuss the organization’s drive to present more PCB design curriculum at the upcoming show and how the show can give designers the tools they need to overcome the many challenges currently facing the industry.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

In this week leading up to Christmas, we have a little bit of everything. Pete Starkey has a review of the most recent EIPC Technical Snapshot, while Tom Kastner discusses the dwindling number of PCB companies in North America. Are we really down to 170 companies? IPC reports that North American PCB sales up 26.1% in November YOY, and the book-to-bill is dead-on at 1.00. Cybord CEO Zeev Efrat explains how his company can provide 100% component inspection. And I have an interview with a student I ran into at PCB Carolina who is working toward his “dream job” on being a technician. As Alex Barile says, he’d hate to work at a desk all day; he likes to install equipment.

Workflow Challenges in Fabrication

Paul Cooke, the senior director of business development for Ventec International Group, is presenting a class at IPC APEX EXPO 2023 that looks at workflow challenges in fabrication, and the myriad drivers that can affect yield, reliability, and cost. Here he discusses the details of this Professional Development course, what he hopes attendees will take away, and why designers and design engineers would benefit from this class.

PCB Carolina: Alex Barile Studying for His Dream Job

Visitors jammed the aisles at PCB Carolina, but I noticed someone who stood out from the crowd: Alex Barile, a student at Wake Tech, a community college in North Carolina. Alex loves the physical and mechanical aspects of machinery, but learned pretty quickly he doesn’t want to be sitting behind a desk all day. He’s found a major that fits both his personality type and professional interests.

Physics, Electrical Engineering, and PCB Design

When I was a sophomore in college, I had an amazing professor for Physics II: Electricity and Magnetism. He made a series of complex topics fun to learn, and his personality and way of teaching were almost tailor-made for the way I like to learn. He explained new concepts through practical examples, and always kept students engaged throughout the class, making sure everyone understood the lectures. Physics II was an engineering prerequisite, and I didn’t mind taking the class since I really enjoyed the material. However, I did find myself wondering a few times, “Will I ever use any physics in real life?” It turns out that the answer to the question was yes.

Tim Haag Celebrates 10 Years as a Columnist

I ran into columnist Tim Haag at PCB West, who was visiting the show with co-workers from the technical writing company First Page Sage. We discussed Tim’s years as a Design007 Magazine columnist, and some of the drivers affecting the technical writing market, such as the retirement of many PCB subject matter experts who were also go-to writers within their companies.

The First India Pavilion

For the first time, IPC APEX EXPO will host an “India Pavilion,” showcasing 16 Indian companies promoting India’s electronics manufacturing capabilities. The initiative was undertaken by the Ministry of Commerce & Industry, Government of India, and implemented by the Indian government agency, Electronics and Computer Software Export Promotion Council (ESC) India.

Taiyo: Reopening Europe for Solder Mask

Nolan Johnson and Stuart Down discuss Taiyo’s partnership with Ventec and how both companies are leveraging their expertise to blaze a trail into the European PCB market. Stuart shares his outlook on the market and the unique challenges posed by global political instability and supply chain constraints, as well as how Europe’s evolving chemical regulations have impacted solder mask formulation. With their sights set on ramping up manufacturing capabilities, Taiyo sees a secure path forward to establishing a sizeable market presence in this promising region.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The holiday season is in full swing for most of us; no matter which holiday you choose to recognize here in the second half of December, it’s almost certain that your routine has some level of interruption to it right now. Chances are, you might not be consuming as much of your usual diet of industry news and information, what with all the holiday treats and traditional meals to be consumed instead. That, gentle reader, is why we bring you this week’s Top 5 editor’s picks–your slimmed down version of the news, leaving you more time for the other delights of the season. So without further ado, we bring you the five news items you really should make room for this week.

NCAB Creating a New Culture of Success

NCAB has been one of the most active companies in the industry when it comes to growth through acquisition, building an extensive global network over time. During the electronica show in Munich recently, Nolan Johnson met up with Greg Nicol and David Grant, both managing directors with NCAB’s UK organization. Greg and David had number of interesting insights on NCAB to share.

A New Gathering Place for Designers

IPC APEX EXPO started out as a show for the PCB manufacturing community, but it’s grown beyond that. This year, there’s more design curriculum at the show in San Diego than ever before. IPC instructor Kris Moyer has been instrumental in leading the organization’s efforts around PCB design and design engineering curriculum. So, I asked him the million-dollar question.

Industry Innovation Starts Here

If it isn’t clear already, your money, time, and effort will be well spent attending IPC APEX EXPO in January. Here, we’ve outlined the top six reasons that this event will be the highlight of your year. We’ve done all we can to make the event not only memorable, but a show that allows you to connect with industry peers, learn how to enhance your skills, help advance the industry, and discover new insights on products and strategies from industry innovators.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

We’re into December, and the new year is around the corner. Things are looking pretty good for our industry. Trade show attendance is back up to pre-COVID levels, and a lot of companies are having banner years. Has the virtual trade show gone the way of the dodo bird? Let’s hope! This week, our must-reads include articles and news items on the decline of R&D, STEM education for kids, why vias do not heat up, the need for more DFT, and the lack of movement toward intelligent data transfer. Designers just love their Gerbers, but Dana Korf has a few ideas about how to make Gerbers obsolete.

Polar Instruments: Simulating PCB Potentialities

Nolan Johnson checks in with Polar’s Martyn Gaudion on the evolving needs of global PCB manufacturing markets in a post-pandemic world, where generating accurate PCB specification documentation is essential to successfully navigating today's rampant supply chain constraints. Polar has positioned itself to meet these needs through agile software product developments that allow OEMs and fabricators to simulate material interactions and end-product specifications, including in-demand features like a comprehensive "structure view" that allows users to visualize all the transmission lines on a given a PCB. Though keeping pace with the demands of a rapidly growing industry has been challenging, Polar's commitment to innovation has kept its software suite ahead of the curve.

The Test Connection: Spreading the Word About DFT

As signal speeds continue to increase and feature sizes decrease, PCB designers are beginning to pay greater attention to test and design for test (DFT) strategies. Bert Horner, president of The Test Connection in Hunt Valley, Maryland, is spearheading this drive to show designers the benefits of a solid DFT plan, as well as the downside of not having a test strategy. I met with Bert at PCB Carolina, where he was exhibiting and presenting a paper during the conference. We discussed his presentation, as well as why designers need to understand test and DFT issues, and why we need to see the PCB as one small—but very important—part of the entire system.

Electronics vs. Physics: Why Vias Don’t Get Hot

Most of are aware that when we pass an electrical current through a trace (conductor), the trace will heat up. This temperature increase is caused by the I2R power loss dissipated in the resistance of the trace. The resistance of a copper trace is mostly determined by its geometry (cross-sectional area), and there are lots of studies trying to look at the relationship between the current down a trace (of known size) and the resulting temperature of the trace. But the situation is much more complicated than this. There are physical properties that exist that result in helping to cool the trace. These properties are usually a combination of conduction of the heat away from the trace through the material, convection of the heat away from the trace through the air, and radiation of the heat away from the trace.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Normally, the holiday season is a slow(ish) news time, but this year just feels different. My opinion is that the technology industry banked up a whole bunch of innovations and new products during the pandemic disruptions, which are coming to market as quickly as possible. The November/December news is full of technology discussion, as my selections this week clearly demonstrate.

Randy Faucette Discusses PCB Carolina’s Explosive Growth

One of the fastest-growing tabletop shows is PCB Carolina, which is held at NC State University in Raleigh. Each year, the show draws more exhibitors than the venue hall can hold, pushing some exhibitors out into the lobby. And this year, the number of registered attendees broke the 1,000 mark for the first time. At PCB Carolina, I spoke with Randy Faucette, the founder of the Research Triangle Park design bureau Better Boards, which organizes this annual tradeshow and conference, and I asked him to share the secret to this show’s expansion.

The Growing Need for UHDI

Jan Pedersen of NCAB Group is deeply involved in IPC standards development surrounding ultra HDI and keeps his finger on the pulse of the industry surrounding this type of fabrication. With Asia still dominating this area, Jan sees the need for U.S. and European PCB fabricators to make the investment if they want to stay competitive.

An Opportunity to Give Thanks

I-Connect007 wants to take this opportunity to give thanks to so many people that make "the magic" happen day in and day out. Thanksgiving is a time, of course, to give thanks for the bounty that we enjoy, and that couldn't be truer each day for the support we receive in editorial, advertising, and marketing of our daily, weekly, and monthly publications. It's a pleasure to contribute to the industry—and to receive contributions. Read our Thanksgiving message and then enjoy your turkey day.

My Experience With Maxwell

I was first introduced to James Maxwell in 1967 as a college student. I had to decide whether I would take the Maxwell fields course or the switching and coding course. Being a chemical engineering major with a co-major in control theory, I had heard about the trials and tribulations of the infamous Maxwell fields course.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

We’re heading into the holiday season, and tradeshow season is in full swing. Managing Editor Nolan Johnson and technical editor Pete Starkey have spent the week in Munich covering electronica, and apparently the attendance was wunderbar. COVID still persists, but everyone is ready to return to some normalcy. There’s a lot going on in our industry. In this week’s roundup, we have articles on everything from rigid-flex to the supply chain, as well as a primer on the role of physics in PCB design. As we move into the new year, you should check out this Top 10 list of tech trends for 2023, courtesy of Gartner.

The Physics of PCB Design

In this wide-ranging interview, Dr. Eric Bogatin discusses the relationship between physics and electrical theory, and why it’s critical for designers and design engineers to understand the laws of physics. As he points out, the math is important, but designers shouldn’t let the principles of physics “hide behind the math.” Eric discusses some points of physics that designers need to understand, the physics resources available, and why it’s so important to have some understanding of Maxwell’s equations, even if you don’t have a strong math background.

DownStream Flexes in Rigid-Flex

During PCB West, I caught up with DownStream Technologies co-founder Joe Clark and Senior Product Marketing Manager Mark Gallant. We discussed some of their latest tool updates, including a greater focus on bringing post-processing functionality, such as inter-layer analysis capability, to rigid-flex circuits. Joe also offered a look at global design trends going into 2023, as more engineers take on PCB designer roles while senior designers are retiring.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The industry news cycle seems to be picking up speed lately. Of course, 30 days into the quarter is about when public companies announce their results, and in the midst of this worldwide financial situation, we’ve got all eyes on anything coming out from our counterparts in the industry. I’ve noticed that global corporate results (Nan Ya PCB and TTM, in particular) do seem to be on everyone’s radar. In addition to financial news, trade shows are popping back up around the world—Europe, India, and a special report from editor Andy Shaughnessy, who took his own road trip to Raleigh, reporting on PCB Carolina, which had its own heyday this year.

PCB Carolina Breaks Attendance Record

PCB Carolina has been growing consistently for the past decade, and this year the show reached a milestone: more than 1,000 attendees. Yesterday, the show was the busiest I’ve ever seen it; I almost had to park off the NC State University campus. Fortunately, I’m an expert at “the parking lot game.” I waited until a guy was leaving and then I sniped his spot. Bam!

IPC to Unveil New Member Magazine, ‘IPC Community’ at IPC APEX EXPO 2023

IPC, in partnership with IPC Publishing Group (I-Connect007) will unveil an exciting new publication, "IPC Community," at IPC APEX EXPO 2023, as a continuation of its commitment to better serve the electronics industry and provide additional value for IPC members.

We’re officially in show season and Managing Editor Nolan Johnson just got back from SMTA International. As he says in his review, the show drew a sizeable crowd this year. With the pandemic in the rear-view window, let’s hope our trade shows are getting back to normal.

The Printed Electronics Roundtable, Part 3

We recently conducted a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In this third and final installment of the roundtable, these experts discuss some of the differences and similarities between PEC and traditional PCB processes, the future of printed electronic circuits, and why the best way to learn about this technology is through networking with veterans of this segment who are eager to share their expertise with the next generation.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Halloween is next Monday and parties will be taking place over the weekend, I’m sure. Here in the United States, at least, the “any-holiday-is-an-excuse-for-a-party” crowd has integrated Halloween, along with Valentine’s Day, St. Patrick’s Day, and Cinco de Mayo into wide-ranging opportunities for themed revelry. The news this week has been a bit crazy as well, though certainly not alcohol-fueled. There was a lot of important news and narrowing it down to just five was thought-provoking yet ultimately rewarding. Here then, are the five top pieces of news you shouldn’t miss this week.

Sunstone’s Matt Stevenson Shares Insights From New PCB Design Book

There’s designing the “perfect” circuit board and then there’s designing a board that is “perfect for manufacturing.” While seasoned designers and design engineers understand many of the nuances, PCB fabricator Sunstone Circuits has just published a new book specifically for new designers who have the knowledge of design but are still learning what it means to get the board manufactured. Sunstone’s Matt Stevenson takes the reader through a series of situations that should help clarify what’s happening in the fabrication process and how to adjust a board design to be better suited for manufacturing.

HDI, A-SAP and mSAP: A Designer’s Point of View

HDI—high-density interconnect—designs require some different thinking on the part of the designer. One of the first things to consider is whether you need HDI, and if so, how much. The HDI option comes into play as soon as you purchase any components with 0.5 mm pin pitch. The number of these components and other specifications of your design will determine the amount of HDI you will need. Here’s a quick list of HDI options.

Forming Standards for Ultra HDI

To get the latest news about ultra high-density interconnections (UHDI), we checked in with Jan Pedersen, NCAB Group’s director of technology. Jan is co-chair of IPC D-33AP, and a great source of overall DFM expertise as well. We asked him to give us a snapshot of UHDI in the industry, where we’re headed, and what this means to PCB designers.

Sunstone and I-007eBooks Launch Book on Designing for Reality

I-007eBooks is excited to announce the release of the latest title in its series for designers, The Printed Circuit Designer’s Guide to… Designing for Reality. This book covers both written and unwritten rules for how to create a realistic, manufacturable design.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Where did the year go? I can’t believe we’re planning our January and February issues now. It was 84 degrees most of last week in Atlanta, and now it’s 31. I guess I should take my Hawaiian shirts out of rotation! This week we have quite a variety of articles for you. It’s officially show time and the industry is back in business in a major way. We have some news coming out of last week’s advanced packaging event in Washington, D.C., and an article about navigating SMTA International, which opens on Halloween this year in Minneapolis. We have a great column on avoiding EMI with good routing strategies, and an article on electrically conductive inks. To top it off, I-Connect007 has published a new book, written by Matt Stevenson of Sunstone Circuits, that posits a new “design for”: Designing for Reality. If you’re a designer, isn’t designing for reality what it’s all about?

EMA Helps Ease Designers’ Supply Chain Woes

Supply chain issues are continuing to cause disruptions in our industry, though lead times have dropped from astronomical to merely troublesome. In this interview, Chris Banton, EMA Design Automation’s director of marketing, explains how Cadence’s software has evolved as designers’ needs have changed in the past few turbulent years, including providing designers with component availability data early in the process.

Q&A: The Learning Curve for Ultra HDI

For this issue on ultra HDI, we reached out to Tara Dunn at Averatek with some specific questions about how she defines UDHI, more about the company’s patented semi-additive process, and what really sets ultra HDI apart from everything else. Do designers want to learn a new technology? What about fabricators? We hope this interview answers some of those questions that you may be having about these capabilities and what it could mean for your designs.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

I’ve been in Washington, D.C., most of this week, attending and reporting on the IPC Advanced Packaging Symposium. You’ll see more content from me in the weeks and months to come as I sort through and highlight the varied aspects of this ground-breaking event. If you’re in this industry, advanced packaging will affect you, make no mistake about it.

Ultra HDI Primer

We recently spoke with Herb Snogren, an industry veteran and consultant with Summit Interconnect tasked with leading the company’s ultra HDI efforts. Herb is co-chair of the IPC ultra HDI subcommittee, IPC D-33-AP. In this interview, Herb discusses the current state of UHDI, how designers and fabricators can get started working in this new frontier, and why the U.S. must invest in UHDI technology now to counteract Asia’s near dominance of the UHDI segment, which has left some of our critical industries vulnerable to supply chain disruptions.

Microvias Can Be Stacked in Certain Package Densities

Summit Interconnect’s Gerry Partida recently spoke with the I-Connect007 Editorial Team about his research into root causes of weak microvias. Rather than a single manufacturing process cause, Gerry suggests that microvia reliability is the culmination of several material interactions and that contrary to popular belief, microvias can still be stacked in small, tight packaging densities. He highlights the need for simulation, as well as some of his findings that he plans to publish in a paper at IPC APEX EXPO 2023.

IPC Symposium: U.S. Must Address Critical Gaps in Advanced Packaging Needs

There is a significant capability gap in advanced substrate packaging in North America, forcing all semiconductors to be packaged in Asia and leaving North America at risk in its supply chain. This was a common theme during a two-day IPC Advanced Packaging Symposium, which launched yesterday at the Kimpton Monaco hotel in Washington, D.C.

Lessons Learned: Breaking Down the Four Types of Communication

Kelly Dack and Nolan Johnson explore the silver linings from the past two years, especially the importance of good communication. These skills are—as they have always been—key to the success of the project. But how do you define the best methods for communication? Kelly breaks down four personality types and why it’s important to recognize how one person differs from another. When you better understand how a person thinks, your level of effective communication increases exponentially.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s been a busy week for I-Connect007. Managing Editor Nolan Johnson and I covered PCB West at the Santa Clara Convention Center, and, as you’ll see in my article below the place was packed. We have an article about SMTA International, scheduled for the end of October. I think the trade show season is looking good into 2023. People are done with COVID shutdowns and ready to get back to live trade shows and conferences. We’ll be in Minneapolis to bring you the latest news and technical information. We also have a news report about the European Union committing to craft its own version of America’s CHIPS Act. There’s a great interview with Dana Korf and John Strubbe about the latest innovations in materials at TUC. And columnist Paige Fiet explains why she is committed to making manufacturing “cool” again to help recruit and retain young technologists.

PCB West 2022 Draws Biggest Attendance in Years

There were more attendees at PCB West 2022 than I can remember in the time that it’s been held in this wing of the Santa Clara Convention Center. The show floor was busier than I’ve seen it in years. For the first couple of hours, the aisles were jammed with attendees, even on the outside aisles. You couldn’t walk without squeezing past other attendees. It was a topic of conversation all day: “How about this crowd? Wow.”

From the Floor at PCB West 2022

Though the organizers of PCB West had soldiered through in delivering a conference every year during the pandemic, the virtual and hybrid models just did not quite meet the requirements for a technical conference. To be fair, the limitations weren’t PCB West’s fault; the shortcomings came from the show’s virtual environments, not the host. All the more encouraging, then, that the 2022 edition of PCB West was back in bloom.

Book Excerpt: 'An Introduction to The Printed Circuit Designer’s Guide to… Stackups'

To give readers a sample of 'The Printed Circuit Designer’s Guide to... Stackups—The Design within the Design,' by Bill Hargin, we are providing the book's introduction. He writes, "Another book about stackups? If you’re asking this question, I’d like to know the book you’re thinking of, as I was looking for it a few years back. I have a pretty good PCB signal integrity (SI) library, and I’ve only found one chapter on stackup design so far."

The Chip Shortage Leads to Innovation

The chip shortage is by no means over, with estimates expecting it will last into 2023. Some could see it taking even longer, such as Intel CEO Pat Gelsinger, who expects it to see shortages into 2024 due to those now impacting electronics production equipment. But if there’s any bright spot to be had, it’s that a crisis often leads to long-term solutions. In this case, it’s the increase in government funding for semiconductor production in the United States. Once the CHIPS Act proceeds, we can significantly accelerate building semiconductor fabs in the United States and work toward preventing future chip shortages that would put us back into our current situation.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week, our five must-reads include the IPC report on the EMS industry and a report on ICs for the automotive market. Add to that Lockheed’s highest powered DoD laser yet, IPC’s APEX keynote announcement, and—for you conference and expo junkies—a calendar of upcoming industry events. I can’t help but notice that much of our news is about, well, something new. In this case, my editor’s picks for the week capture new technology, new perspectives, new ways to communicate content, and new developments that we can expect to see in our future daily life. To borrow a phrase from the TV show “Firefly,” everything is “shiny” this week. I will be at PCB West, the IPC Advanced Packaging symposium, SMTA International, and electronica. If you see me, say hello, and share something cool about the part of the industry you’re in.

DFM 101: Final Finishes—ENEPIG and IAg

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. Final finishes provide a surface for the component assembler to either solder, wire bond, or conductively attach a component pad or lead to a pad, hole, or area of a PCB. The other use for a final finish is to provide a known contact resistance and life cycle for connectors, keys, or switches. The primary purpose of a final finish is to create electrical and thermal continuity with a surface of the PCB.

Catching Up With John Johnson, New Director of Business Development at ASC

It’s always good to catch up with old friends, especially when you can start working together. I recently spoke with my friend John Johnson, who has joined American Standard Circuits as the director of business development. At ASC, John will be using the Averatek A-SAP process that he was previously involved with. He shares some of his background and provides insight on the best ways to use this semi-additive PCB fabrication process that opens the capability window for forming trace and space.

Book Excerpt: The Electronics Industry’s Guide to… The Evolving PCB NPI Process, Chapter 1

The Electronics Industry’s Guide to… The Evolving PCB NPI Process is the first book in I-Connect007’s new The Electronics Industry’s Guide to… technical series. This valuable resource is for all segments of the electronics interconnect industry. What follows is an excerpt from Chapter 1: 'How the NPI Process Has Changed and Where We're Going'.

Some Relief, But Hold Off on the Party

To help PCB designers and design engineers get a clearer picture of the stress points in the industry, particularly from a company that deals directly with EMS providers, we reached out to CalcuQuote CEO Chintan Sutaria with a list of questions. The following Q&A explores trends in the PCB supply chain and heady advice for dealing with long lead times and counterfeit parts.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s officially fall now, and in Atlanta the temperature has plummeted to the mid-80s. We’ve all bumped our air conditioners up to 74 degrees. That means it’s trade show season, and I’ve been busy looking for my suitcase. This week, we have an assortment of news about associations, education, and advocacy, as well as another installment of our Printed Electronics Roundtable. And if you’re looking for a job, you are in luck; our jobConnect007 section is chock-full of open positions at all levels in this industry.

Pack Your Bags! We’ve Got Your Trade Show Calendar Here

It’s officially fall, and that means it's time to start planning your trade show attendance. To help you make decisions about when and where to go, we’ve put together a list of industry trade shows. It has been two long years with no or few in-person trade shows, and we’ve felt it. So, now we’re back in business and ready to hit the road. Do you have a show or conference to add to our list? Let us know!

Part 2: The Printed Electronics Roundtable

We recently held a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In the first part of this roundtable, the team dispelled a variety of myths surrounding PEC. In this second part of the roundtable, the participants discuss what designers and fabricators need to know to jump into printed electronics, and some of the drivers behind this growing technology.

IPC: Companies Are Intentional About Tracking Environmental and Social Risks

Leading companies in the electronics manufacturing industry are highly intentional about their environmental, social and governance (ESG) priorities, with climate change and energy use among the most closely scrutinized issues, an IPC analysis shows. As part of IPC’s ESG for Electronics initiative, IPC is interested in developing resources for members on the most common ESG methods and priorities of leading companies across the electronics value chain. In support of this, IPC has preliminarily analyzed the ESG reports of approximately a dozen companies in selected portions of the industry.

A New Sourcing Paradigm

We’ve seen many changes over the past few years, and nowhere are they more evident than in the world of sourcing components. Sourcing has become one of the biggest challenges facing PCB designers and design engineers today. Gone are the days of procuring parts from a single source, and communication between stakeholders and distributors is critical. But as we learned in a conversation with I-Connect007 columnist Kelly Dack, PCB designers can use certain layout strategies to plan for the unexpected, such as leaving extra real estate so that smaller components can be replaced by larger, readily available parts if the originals become “unobtainium.”

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

“You are the average of the five people that you spend the most time with.” This saying is attributed to Jim Rohn, and I couldn’t help thinking of that quote as I put together this week’s listings. Hear me out: 1) There are five items on our list; 2) These items zoomed to the top based on reader interest; 3) Every single one of these news items has an “association” association—IPC, iNEMI, SMTA, and NextFlex are all represented in what you, dear reader, chose to explore this last week.

Altium’s EDDI Report Tracks Components’ Availability—Today and Historically

There’s one lesson that all designers have learned over the past few years: Components might be here today and gone tomorrow, so tracking your parts is more important than ever. Any resources that help you keep tabs on your required parts are invaluable in these days of 40-week lead times. Earlier this year, Altium released one such resource: the Electronic Design to Delivery Index (EDDI) report. Assembled from millions of bytes of data gleaned from the Octopart search engineer and the Nexar platform, the monthly EDDI report provides part availability histories going back years, as well as a real-time snapshot of global inventories.

Designing Through Supply Chain Pain

Engineers are accustomed to the demanding challenges of designing for miniaturization, cost reduction, cross platform compatibility, and harsh environments. What has proven to be the most painful experience of my career (and for many of my colleagues) is the sheer lack of components from which to build our designs. Development cycles—commercial, industrial, medical, avionics—have been severely impacted, from large enterprise corporations to small design/integration companies. Awareness of the situation is the first step to understanding the underlying problems faced by today’s design engineers industry wide. Here are a few of the situations I have faced in the last year alone.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It feels like the first day of school. It’s September, and we’re all officially back at our desks, workstations, or kitchen tables. Even Les Vacances is over. Oui, c’est vrai! But instead of facing new teachers, we have to deal with diverse market forces, supply chain issues, and technology that never seems to stop evolving. Of course, that’s what makes this industry so interesting, isn’t it?

September 2022 Issue of Design007 Magazine Available Now

Supply chain management is a dynamic situation, with a number of global forces that can create pain for PCB designers. In this issue, we speak with a variety of experts and bring you up-to-the-minute insight about designing PCBs in this ever-changing environment.

Ventec Thermal Management Book Excerpt: Chapter 1

Regarding basic principles of thermal dissipation there are three ways of dissipating energy: Conduction, convection, and radiation. The integrated metal substrate (IMS) printed circuit boards rely predominantly on heat conduction all the way through the different layers of the substrates from a hot point (the base of the component) to a cold point (the furthest surface of the metal base) and, usually, thereafter, through a dissipator.

Material Conservation: The PCB Designer's Role

During these times of supply chain uncertainty, many product developers are considering new ways to conserve materials—from laminates to components, layer reduction, and everything in between. Barry Matties and Happy Holden recently spoke with Alun Morgan, president of EIPC and technology ambassador for Ventec, about material conservation strategies for today’s PCB designers and design engineers. Alun explained why this may be the perfect time to educate PCB designers about conserving materials: When a model is broken, the people involved are much more open to new ideas.

Designing for Material Conservation Means Changing Attitudes

It makes a lot of sense: During times when the supply chain is stretched to the breaking point—and the last few years certainly qualify—what if PCB designers created boards that used fewer components and less laminate? Do PCBs still have to be 0.062" thick? Why not reduce layer count while they’re at it? Andy Shaughnessy and Nolan Johnson spoke with I-Connect007 columnist Dana Korf about the idea of designing a PCB with material conservation in mind. Is it a great new idea, or are we opening a whole new can of worms and a separate group of problems?

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week we have quite a variety of articles for you. There has been so much electronics industry news coming out of Washington, D.C., that it can be hard to keep track of what’s going on. So, Editor Michelle Te compiled a handy-dandy reference guide to recent legislation news, including our exclusive coverage. We need to keep an eye on these senators and representatives. They’ve been talking about the importance of our industry for the past year, but this is an election year, after all. They’ve been known to say one thing and do another.

I-Connect007 eBook Introduction: The Evolving NPI Process

Thanks to marketing and advances in technology, we have all come to expect that the electronic products we buy will be closely aligned to our individual and specific lifestyle or business requirements. This expected variability, in personal function and style, as well as regulatory compliance and a changing global economic landscape, has made designing and producing new products a challenging prospect. And, on top of the resulting “high-mix, low-volume” production cycles, increasingly more products contain electronic components in varying levels that heighten the complexity of design and manufacturing.

Design Tips for Lowering Costs of Fab and Assembly

This is the million-dollar question of every project: How can I cut the cost of the PCB? There are about a thousand answers to this question. There are a few simple guidelines that everyone can follow to reduce costs. I talk about them in my IPC CID and CID+ courses. Designers, fabricators, and assemblers talk about them in a variety of articles. Some professionals who have published some great articles on cost-saving strategies include Tara Dunn, Happy Holden, Chris Church, Kella Knack, Judy Warner, Julie Ellis, Lars Wallin, and many, many others.

Happy’s Design Tips for Material Conservation

For this issue, Happy Holden provided a range of options for designers who are seeking to conserve materials in their next design. He also offered an example of the relative cost index, or RCI, that he developed at HP exclusively for PCB design. With this RCI, designers can figure out the relative cost of a new design compared to an eight-layer through-hole board. We hope you can use this handy formula on your next design job.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Can it be Friday already? Seems like I’ve just barely put away my Tuesday dishes. Some weeks, I wonder where my days went as they fly by so fast I hardly even realize it. As I looked back through the news for the week, it was clear why everything went so fast: There was a lot going on. The news this week had a nice feel to it. It seems like the industry is starting to gain some traction again with shows, mergers and acquisitions, and companies getting to do those “extras” that they wanted to do before the pandemic reared its ugly head. It had a little of that “back to normal” feel, even if we aren’t quite there yet. What do you think? Are we normal yet?

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

There was some good news this week, as Republicans and Democrats managed to cooperate long enough to pass the CHIPS Act. Members of the House and Senate don’t usually act until they get worried about being voted out of office, so pardon me if I’m not ready to sing “Happy Days Are Here Again” just yet. But this is still really good news; the politicians are on the record now, and we can hold them accountable.

Cadence Provides ‘Clarity’ in Design Tool

Nolan Johnson recently spoke with Brad Griffin, product marketing director for Cadence Design Systems, about Cadence’s Matrix solver technology. They discuss its use as a multi-disciplinary field solver as well as Cadence’s focus on thermal analysis and utilizing the power of the cloud.

Myths vs. Facts: The Printed Electronics Roundtable, Part 1

We recently held a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In this first part of the roundtable, the participants dispel 10 common myths that have been floating around regarding printed electronic circuits (PEC). They also discuss the progress that’s been made in PEC development in just the past decade, and what the future may hold for this technology.

John Watson Wants You—to Sign Up for His PCB Design Class

I-Connect007 columnist John Watson is teaching an introductory class on PCB design at Palomar College this fall, but this is much more than a basic design class. But John has hit a slight snafu: He needs a few more students to sign up before Aug. 23, or the class will be cancelled. It’s an online class, so you don’t have to live in San Diego to attend. In this interview, John talks about the genesis for the class and its benefits.

Excerpt Chapter 5: 'The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Vol. 2'

Chapter 5 of the 2nd Volume from The Printed Circuit Designer's Guide to... Thermal Managment with Insulated Metal Substrates provides examples of thermally enhanced prepregs and cores now available in the market with the versatility to solve a wide variety of challenges. Included in this chapter you will find examples of simple designs and more complex hybrid assemblies that combine multilayer and single-layer areas on the same board.

August Issue of Design007 Magazine Available Now

We’re seeing all sorts of interesting tactics for dealing with 50-week lead times. One of the most basic concepts that we’ve heard about lately is material conservation—why not just design PCBs with fewer parts? As we point out in this issue, sometimes less is more. Our experts share a variety of strategies and technologies to help reduce your overall material consumption, allowing you to lower costs and add competitive advantage.

IPC's I-Connect007 Acquisition Update With John Mitchell

Editor Nolan Johnson speaks with I-Connect007 Publisher Barry Matties and IPC President and CEO John Mitchell about IPC's acquisition of the publishing company, and what this means to I-Connect007's readers.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The Top 5 list this week contains industry analysis from IPC’s Shawn DuBravac, news on the passage of the U.S. “CHIPS Plus” bill, new materials from Ventec, news about a fab for sale, and a chemistry company completing their acquisition, plus a brand new book in the I-Connect007 eBooks series.

HyperLynx: There’s an App for That

I recently spoke with Todd Westerhoff, product marketing manager for signal integrity software tools at Siemens. We discussed a new capability called HyperLynx Apps that offers a new take on traditional signal and power integrity analysis, and how that fits in with the Siemens plan to put SI and PI tools into the hands of more designers early in the design cycle.

DFM 101: Final Finishes—ENIG and ENIPIG

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. Final finishes provide a surface for the component assembler to either solder, wire bond, or conductively attach a component pad or lead to a pad, hole, or area of a PCB.

Q4 Concerns: Hold on to Your Hats

IPC Chief Economist Shawn DuBravac has plenty to share about the state of the U.S. economy and how the electronics manufacturing industry might weather the storms of high inflation, rising interest rates, and low unemployment. It’s an interesting situation to find ourselves in as the flurry of opinion on a 2023 recession starts to take shape. Does it make sense to invest in PCB fab now? And how does the rest of the world feel about it? Shawn gets to the bottom line.

Excerpt: 'The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Vol. 2'

As the second in this two-part series, The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Volume 2, by Didier Mauve and Robert Art builds on the material presented in the first book by describing up-to-the-minute products and design techniques for thermal management with IMS.

New Book from I-Connect007 Examines Evolution of Electronics Industry NPI

The Electronics Industry’s Guide to… The Evolving PCB NPI Process is the first book in I-Connect007’s new The Electronics Industry’s Guide to… technical series. This valuable resource is for all segments of the electronics interconnect industry.

Webinar Review: Thermal Integrity of High-Performance PCB Design

Electrical and mechanical engineers may be working on the same product development teams, but they speak different languages, and they have completely different objectives. As a result, these folks almost never use the same software tools. But Cadence’s new Celsius Thermal Solver is an exception to the rule. In a new CadenceTECHTALK webinar, “How Static and Dynamic IR Drop Analysis Can Help PCB Designs and Challenges,” product manager Melika Roshandell and SerDes SI/PI engineer Karthik Mahesh Rao explain how the EE and ME can both use the Celsius Thermal Solver to achieve their disparate objectives.

The Practical Side of Using EM Solvers

Electromagnetic (EM) solvers based on Maxwell’s equations have proven invaluable in the advancement of digital electronics and wireline communications. Plain and simple, electrical engineers need to know what a circuit or electrical interconnect will do when excited by a dynamic or varying signal. In the signal integrity world, an interconnect that passes a DC connectivity check can completely fail at higher frequencies. In the power integrity world, a power rail that measures the correct DC voltage could easily go into oscillation when a dynamic load is applied. Learning the basic skills to fire up an EM simulator, obtain qualitative answers in minutes, and higher fidelity answers in a few days, can be the difference between sleepless nights of product failures vs. robust designs with wide design margins.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Our biggest news this week: I-Connect007 has been acquired by IPC. Every member of the team, including founder and Publisher Barry Matties, is included in this deal. We’ve enjoyed working closely with IPC for decades, especially at events like IPC APEX EXPO, and we have four IPC columnists writing in our magazines and newsletters. This move makes sense for both parties. It enables us to take our magazine, newsletters, and book publishing to the next level, and IPC won’t have to spend years building a media company from the ground up. It really is a win-win.

IPC Acquires Media Company I-Connect007, Strengthening Relationship to Drive Growth and Innovation in the Electronics Industry

IPC, a global electronics manufacturing industry association, has acquired media company I-Connect007, a global source for news and original content serving the printed circuit design, fabrication and assembly/EMS markets.

The Great Divide in PCB Simulation Software

Today’s PCB design engineers have more layout and analysis tools at their disposal than ever before. Over the years we’ve seen layout tools become more automated, rules-driven, and more integrated. Now we even have integration between design tools from different vendors and ranging across domains, starting with basic circuit design, and spanning up to PLM and ERP integration. It really is a great time to be a designer.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s always interesting how certain groups of news emerge in our most-read content. This week, reader interest seemed focused on two distinct themes: Mexico and awards. In this week’s list, we find the inaugural award recipients from iNEMI’s Project Leadership Awards. We also bring you the award recipients from the SEMI FlexTech conference held last week in San Francisco. News from Mexico includes a new Atotech facility, and an interview with IPC’s David Hernandez and Lorena Villanueva about IPC’s expanding presence in Mexico. Metcal’s new hot air rework system also got a lot of attention, with an abundance of reader interest.

The Importance of Rigid-Flex PCB Design Guidelines

I have the tendency to try to replicate the delicacies I’ve ordered at restaurants in my own kitchen. One of my latest attempts at creating restaurant-worthy dishes was a Korean pancake that’s crispy on the outside but soft on the inside. With my amateur cooking skills, it proved to be an impossible task—I could either make only a hard pancake or one that was total fluff. While I’m still struggling to figure out the trick to bringing together the different textures of a Korean pancake, I’ve had more success in bringing together the hardboard elements and flexible PCB elements of a rigid-flex PCB. Compared to making Korean pancakes, striking the right balance of flexibility and rigidity on a rigid-flex PCB is easy if you abide by rigid-flex PCB design guidelines.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

I’m getting a lot of out-of-office replies. Are you all on the beach now? It’s 91 degrees every day here in Atlanta lately, but each afternoon it rains like we’re in a horror movie, and that drops the temperature down to the subtropical arena. Still, I’ll take heat over freezing any day. Things are heating up in our industry too, as we see from my top five choices this week. First-quarter electronic design revenue is up year-on-year, but PCB revenue barely moved the needle YOY. Editor Nolan Johnson spent the week at SEMICON West and the FLEX Conference, and he brings us a review of these conferences, co-located at the Moscone Center in San Francisco. As he notes, printed electronic circuits are beginning to gain a foothold in the market.

Surveying the Land of Field Solvers

Electromagnetic field solvers have traditionally been used by a small slice of engineers—the full-time signal integrity experts—and their use has been limited to the most demanding designs. But as design speeds increase, problems requiring field solvers are becoming more mainstream and field solvers are popping up all over the place, including free or inexpensive solvers available through an internet search. Many companies are claiming that their field solvers can be used by hardware design engineers without the SI background that solvers once required.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

In more than one conversation while discussing the industry this week, the themes have included industry turmoil, lots of business opportunities, and the urgent need to build out to meet changing demands. In fact, our July issue of PCB007 Magazine, which publishes later this month, will focus on these very topics. It’s definitely one not to be missed! These themes also emerged in this week’s top five news items as well. Top stories include an acquisition in the soldering machinery space, sales and service expansion in Mexico, industry data from SIA on semiconductor global sales data, and strong financial numbers from two China-based manufacturers. Now, with the U.S. Congress putting its focus on the PCB industry, things could really heat up. It’s going to be an interesting year.

What Happens When You Assume?

What is design with manufacturing and what does true DWM look like in operation? In this interview, I-Connect007 columnist Dana Korf explains what it will take to achieve total communication among all the stakeholders in the PCB development cycle. He also stresses the need for everyone involved in PCB design and manufacturing to stop making assumptions, even at the risk of being labeled as “that guy” who asks too many questions.

In this interview with Arjun Bangre, director of product for high-speed interface IPs for PCI Express and CXL at Rambus, the discussion revolves around new developments in CXL, PCI Express, and interoperable IP solutions that Rambus has developed.

Master the Art of Communication With Manufacturers

As mentioned in the May issue of Design007 Magazine, design is performed, at times, in a vacuum. But it doesn’t have to be that way. Whenever circumstances allow, design should be performed by communicating with all stakeholders throughout the design process, hence the emphasis on the word with in DWM. Communication can occur through personal correspondence such as email and voice conversations or through more formal design meetings—in person or through videoconferencing. No matter which means of communication you prefer, it’s important to communicate early and often with stakeholders involved in the downstream processes as you bring your project to realization.

EIPC Summer Conference 2022: Day 2 Review

Örebro, Sweden on June 15 brought a bright and early start to Day 2 of the EIPC Summer Conference for those who had enjoyed the previous evening’s networking dinner, but had resisted the temptation to over-indulge or to carry on their long-awaited catch-up conversations with old friends into the small hours. All but a few were in their seats for 9 a.m., awake and attentive for Session 4 of the conference, on the theme of new process technologies, moderated by Martyn Gaudion, CEO of Polar Instruments.

Market news was certainly big this week. While the U.S. stock market continues make some large swings, the PCB and PCBA are doing their own dance with the numbers. We’re still feeling the effects of the pandemic, but it seems to be more about playing catch up. Still, the industry is showing some instability, both in positive and negative ways.

The Survey Said: Why Don’t You Know Your Fabricator?

When we want to find out what challenges our readers are facing, we just ask. And they don’t mind sharing—the good, the bad, and the ugly. In a recent survey, we asked our PCB designer readers, “Why don’t you know who is going to manufacture your boards?” Here are some of more interesting replies we received, edited slightly for clarity. Do you see yourself in these replies?

We’re still not officially into summer yet, but Atlanta is bringing the heat, baby! It’s hit 97 degrees a few times this week, and I now have a fan aimed right at my face. At least it’s nice and humid too. I’m glad I don’t wear make-up. And it’s been a hot week in the circuit board community. This week, Eltek reported a fire at a board shop in Israel, and Flex committed to building a 145,000-square-foor facility in Jalisco, Mexico to serve the electric and autonomous vehicle segment.

Producing Diverse Designs in Concert With Manufacturing

There is a new acronym bubbling up in the design world: DWM, which stands for “design with manufacturing.” Why is this different than design for manufacturing, or DFM? With DWM, the emphasis is on integration between the design team and the manufacturers during the design process. DWM is much more than that. We are tasked with producing designs that meet various technical requirements, yet are cost-effective and manufacturable. We provide this service to hundreds of customers who have varying degrees of processes, tools, and manufacturing partners. Given this diversity, we have recognized the importance of designing with manufacturing to achieve the product development goals of manufacturability and technical excellence.

It certainly seems that our times continue to be interesting, don’t they? Just how many different flavors of supply chain disruption can we come up with? Investment on the supply side needs to increase, but the size of the labor force needs to increase even more, if we want to accomplish the task of the buildout itself, let alone running the facilities properly.

DFM 101: Solder Mask and Legend

One of the biggest challenges facing PCB designers is understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers from the PCB manufacturer’s perspective, and the design decisions that will impact product reliability.

Designing PCBs With Additive Traces

Advances in technology have been clear to see within the component packaging industry, as the ball grid array (BGA) package sizes reduce from 1.0 mm pitch to 0.8 mm, 0.4 mm, and even beyond. However, while these improvements have occurred with component packages, it has become increasingly more difficult to break out and route the dense circuitry associated with these parts. Currently, the high-density interconnect (HDI) method typically used for the breakout of such parts has been to create the smallest possible subtractive-etched traces with microvias to allow for connections and escapes on the innerlayers of your PCB.

Designing Additive and Semi-Additive PCBs

With components getting smaller and electronic devices becoming more compact, we are reaching the physical limits of the typical etched fabrication processes. To address these limits, new additive and semi-additive processes are being developed to fit into the current fabricators’ production lines without too much disruption or extra cost.

Spring has definitely sprung, and the trade show season continues to roll right along. Managing Editor Nolan Johnson just returned from DesignCon 2022, and as he says in his review, the attendance was up from last year’s event, which had been at the McEnery Convention Center in the waning days of the pandemic. I hope we’re getting back to normal, whatever that means. This week, we have a few articles about Industry 4.0, as well as a column on setting your priorities. We have a cool article about methods for measuring the breakdown of resins during multiple thermal laminations, and a conversation with an EMS company president who realized that he was actually running a data collection firm that happened to make circuit boards. Can you say the same about your own company?

DesignCon 2022: Back to Business as Usual

It was something of a homecoming as DesignCon returned to the Santa Clara Convention Center this week for DesignCon 2022. It’s been two years since the last DesignCon was held in this venue just before the pandemic began. I attended DesignCon 2021 at the San Jose McEnery Convention Center in July of last year, and I could see a big improvement in attendance as DesignCon moved back into its usual venue.

It’s been a crazy week, with lots of bad news coming out of Ukraine. (I’m a news junkie by trade, but I confess that some days I just unplug from the news completely to avoid overdosing on negativity.) And, as you might have guessed, this is all having ill effects on our electronics supply chain, which is already stretched thin. This is reflected in our IPC news item that shows an uptick in PCB sales in February, but a drop in bookings YOY, in part due to the trouble in Eastern Europe. But there’s positive news in this week’s top reads. We have a NextFlex article about an innovative flexible technology called flexible hybrid electronics (FHE) and a great interview by Dan Beaulieu. We also have a column by Travis Kelly, who discusses PCBAA’s efforts to lobby for American manufacturing in Washington. And last but not least, let’s welcome our two newest columnists, Paige Fiet and Hannah Nelson, who discuss their excitement about entering this industry.

AltiumLive 2022: Alex Sapp on How to Create a Better BOM

I recently spoke with Alex Sapp, director of API commercial strategy at Octopart, about his AltiumLive presentation, “How Resilient is Your BOM?” In this interview, Alex details the takeaways of his class, and some tips and techniques for creating more reliable BOMs and dealing with the current supply chain uncertainties.

Book Excerpt: 'The Printed Circuit Designer’s Guide to… High Performance Materials', Chapter 1

Choosing the right material for your application can be a major challenge. These are “cost to performance” decisions that need to be made to select material that will meet the expected performance requirements and the desired cost targets. Selecting a material that meets cost targets but fails to perform in prototype development testing results in costly revision spins, cost increases and delays to market. Chapter 1 of this book helps readers understand what resin choices to make for optimal electrical performance.

Planning Your Design Education: Keep an Open Mind

Rea Callender is the new vice president of education for Altium. He brings a background in business development and entrepreneurship, along with experience in K-12 education.

It’s Friday, and I’ve spent the last few days breaking in my new laptop. It’s a Mac, and it’s been a while since I used one of these. It occurred to me that the last time I used a Mac, there was no email and no internet. I was editor of my college newspaper. I had just voted for Clinton, because that’s what you did in your 20s. We had Apple Classic II monitors with screens the size of a postcard, and we were on the cutting edge of desktop publishing. Students submitted articles on 3.5” loppy disks or on notebook paper, sometimes written in pencil. That’s where I learned to edit, and to do it quickly. We won awards every year. Good times.

AltiumLive 2022: Left-Shifting Modeling and Simulation

Harry Kennedy and Sarmad Khemmoro of Altair recently spoke with Andy Shaughnessy about their AltiumLive presentations, which are now available online. They discuss the need for modeling, simulation, and verification in PCB design, and why these actions should be performed as early in the design process as possible.

Planning Your Design Education Strategy

If you’re a new PCB designer, you might be asking yourself: How do I set up an education and training plan for my career in PCB design? We asked Eric Bogatin to weigh in with his thoughts. Eric has a unique viewpoint: He’s a veteran signal integrity instructor, as well as a professor in the College of Engineering and Applied Science at the University of Colorado, Boulder. In this interview, Eric lays out some of his planning strategies and the need for a degree in electrical engineering in the PCB design world.

Happy Holden Reflects on Successful IPC APEX EXPO 2022

The attendance at this year’s IPC APEX EXPO seemed higher than I expected, so thank you all for making the necessary arrangements to attend. However, we sorely missed many of our foreign contributors and friends. One of my cherished reunions was with Pete Starkey, who fought through the red tape of government restrictions to make his way from England for the show. Both of us were able to help conduct interviews with many of the industry’s business and technical leaders. For that, I am grateful.

IPC Student Director: Three Things IPC APEX EXPO Taught Me

IPC APEX EXPO 2022 was my first in-person APEX EXPO event, and it surely did not disappoint. The show this year was packed with high quality technical courses, engaging professional development courses and, of course, an admirable show floor exhibition. This year APEX EXPO really resonated with me, and I would like to leave you with three insights I learned while attending.

In the news this week we found a synchrony of topics. Much of the world is aware of the speaking points from U.S. President Joe Biden’s State of the Union address this past Tuesday. In that speech, President Biden talked prominently about U.S. legislation in process to bring more technology manufacturing back to the states. In fact, Intel CEO Pat Gelsinger was not only an invited guest, but was referred to directly in the speech as a positive example. I can only assume that President Biden meant that moment to be a motivator for other CEOs in the industry.

The IPC STEM Event Inspires

Once again, IPC APEX EXPO featured its successful STEM event, organized by the IPC Education Foundation, and sponsored by several companies, including I-Connect007. The event had nearly 80 students in person for a hands-on introduction to our industry. After the welcoming comments, the students broke into groups for different activities. While some enjoyed a guided tour of the show floor, upstairs the other students learned how to solder. Then they rotated so that they all had the same opportunities.

DFM 101: Plating Methods

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. There are two methods of plating copper on PCBs—pattern plating and panel plating. The panel plating method eliminates most of the copper plating distribution issues, but because it adds copper thickness to the base layer, it makes maintaining fine line definition and consistency difficult.

David Pogue Keynote Opens IPC APEX EXPO 2022

There were just a few empty seats in the huge, main lecture hall of the San Diego Convention Center on January 25 as IPC APEX EXPO welcomed the opening keynote speaker, science and tech writer David Pogue. Despite the early time of 8:30 a.m., the crowd enjoyed his topic, “Disruptive technology and how it will affect your business: What’s coming by 2026?” Pogue took us on a short journey through some of the technological innovations that continue to accelerate the transformation of our lifestyles and gave us a preview of how we might succeed in a world we’ve never seen before.

AltiumLive 2022: Robert Feranec Takes Aim at 'Aha' Moments

I recently spoke with Robert Feranec, the founder and CEO of the FEDEVEL Academy. He’s a well-known hardware engineer and something of an industry “rock star” on YouTube; his channel provides tips and techniques on digital design and engineering, with some videos clocking 400,000 views. I asked Robert to discuss his AltiumLive 2022 presentation, “Aha, That’s How it Works.” As he explains, much of an engineer’s life involves making these little “Aha!” discoveries that challenge the way they look at electronics.

As soon as we got home from IPC APEX EXPO 2022 we started work on our post-show publication, Real Time with… IPC APEX EXPO 2022 Show & Tell Magazine. Now in its fifth year, Show & Tell is the best—and most exhaustive—source of in-depth information about IPC APEX EXPO. We published Show & Tell this week, and the response from industry leaders has been off the charts. Show & Tell gives the reader a taste of what it was like to be at the show, from ribbon-cutting and keynotes through the last conference classes.

AltiumLive 2022: No Shortcuts to Disciplined Library Management

I recently met with Altium’s John Watson for a discussion about his AltiumLive presentation on coping with design challenges, particularly in library management. As John explains, with library management, there’s no substitute for sitting down and doing the hard work, particularly during times like these, with a supply chain that is erratic at best. He also discusses his new job at Palomar College, teaching basic and advanced design techniques to students who are often seeking the “easy way out” in PCB design.

AltiumLive 2022: Power and Signal Integrity—Return to Sender

I recently spoke with Heidi Barnes and Stephen Slater, both engineers with Keysight Technologies, about their presentations at this year’s virtual AltiumLive. They discussed ways to avoid signal and power integrity challenges later by following simple board design practices early on, how SI and PI are interconnected, and why the return path must be more than an afterthought in high-speed designs.

Finally! A Book About PCB Stackups

‘The Printed Circuit Designer’s Guide to… Stackups: The Design within the Design’ is the latest addition to I-Connect007’s comprehensive, educational library. In this book, brought to readers by Siemens Digital Industries Software and I-007eBooks, author and stackups expert Bill Hargin discusses materials, laminate datasheets, impedance planning, and more. This book provides the reader with a broader understanding of stackup planning and material selection in an effort to comprehend what Hargin calls “the design within the design.”

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Here in the Northern Hemisphere, we’re now closer to the equinox than to the solstice; change is in the air. Where I live in the Pacific Northwest, we’ve had unseasonably mild and sunny weather, teasing us that spring might be right around the corner. Change is in the air in our news feeds, too. This week, we bring you on-the-grow news from NCAB and Aegis, some market reports on smart manufacturing, and a widely read column on cybersecurity from Mehul Davé. Now that’s something to warm up to.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

This week’s picks comprise a potpourri of published articles, a hodgepodge of helpful hints, and a brood of business news. Our collection includes several interviews from IPC APEX EXPO; we filmed over 60 of these video interviews that week, all shot with our new anti-COVID protocol. The boom microphones, selected so that we wouldn’t have to attach clip-on mics to each interviewee, gave our booth/studio an air of 60 Minutes. But unlike what we see in most news shows, almost all the news at IPC APEX EXPO was positive as companies emerge from the pandemic with even more innovative software, services, and equipment than before. It’s looking like 2022 is going to be a really good year.

Changes on the Horizon: Is Resistance Futile?

For printed circuit engineers, especially those of us who have been in the industry for some time now, change is inevitable. From customer requirements that lead to design changes and deadlines being pulled in, to decreasing budgets and resource reallocations, change is one area where we must be adaptable if we want to survive and be successful in today’s industry. Engineering change orders (ECOs), schematic/drawing redlines, component placement adjustments, and mechanical features modifications are among the changes that most of us usually deal with at one point or another during a project’s design cycle.

Real Time with... IPC APEX EXPO 2022: New Materials for Additive Manufacturing

Trevor Polidore of Rogers Corporation and I-Connect007 Guest Editor Tara Dunn discuss the introduction of the new Rogers materials designed for use in 3D printing.

Keep the Change? No, Embrace It

In a world where technology is so quickly evolving, we really shouldn’t be surprised that companies and professional events have gone virtual. Change can be daunting, but as we all master navigating life in this “new normal” (don’t you hate that term?), we realize that not much of our professional lives has changed. You still have to go to work every day, but now you just do so from the comfort of your home, and you don’t interact with people in person. Obviously, the global pandemic had a massive impact on work culture. Even though the situation with the virus is slowly improving, a lot of companies are still maintaining a flexible workplace.

High-Voltage Circuit Design Guidelines and Materials

The Hubble telescope, the Cassini-Huygens mission, and other exploratory spacecraft utilize high-voltage DC power supplies for everything from vidicon camera tubes and mass spectrometers to radar and laser technologies. NASA has experienced performance problems with the 1.5 kV supplies because—as a 2006 report stated—“designers did not take the high-voltage problems seriously in the initial design.” The report cited very narrow parts parameters, electrical insulation problems in dielectrics, ceramics, bad geometries, small spacing, the use of the wrong insulating materials, and thermal expansion as causes for the power supply failures.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

The last time I was in this space, we were busy preparing for our extensive coverage of IPC APEX EXPO, so now I have the honors of compiling the news from the week following the event. We often use the phrase “busy news week” in these compendiums, but this week I have metrics—25% more news items published this week at I-Connect007 than our weekly average. All the more reason to read the website newsfeeds and newsletters, but also all the more reason for me to bring you the best of the best from the past week.

AltiumLive 2022: Stopping Your EMC Problems Before They Start

Todd H. Hubing has been working with EMC for decades. He began as an engineer at IBM, then served as a professor at the EMC lab at the University of Missouri-Rolla (now Missouri Science and Technology), and later moved to Clemson, where he founded the Vehicular Electronics Library. Now, Todd is focusing on his most recent endeavor, LearnEMC. At AltiumLive 2022, Todd shares his thoughts on how to avoid EMC issues before they have a chance to wreak havoc on your board, simply by making smart decisions early in the design process. As he points out in this interview, this is much better than waiting until you have EMC issues later on and possibly redesigning a board until you pass EMC.

IPC runs on the contributions of its tireless volunteers, and a group of these engineers and technologists were honored at yesterday’s Awards Luncheon. The traffic on the show floor was steady most of the day, and we saw a constant stream of visitors in the I-Connect007 booth and studio.

AltiumLive 2022: Keep Your Boards From Screaming with Eric Bogatin’s EMI Tips

I recently spoke with Eric Bogatin, the “signal integrity evangelist,” about his AltiumLive keynote presentation, “How to Keep Your Boards from Screaming Like a Banshee.” Eric explains how attention to board structures during the early stages of PCB layout can keep EMI from becoming a problem in your design. He also discusses a feature of Altium Designer that some designers may not know about—a 2D field solver that's part of the Simbeor high-end electromagnetic measurement tool, but with a simple GUI that most designers can master right away.
