Ken Wyatt: Think of Circuit Traces as Wave Guides

We spoke with Ken Wyatt of Wyatt Technical Services during DesignCon 2021. In this interview, Ken discusses his DesignCon tutorial and how proper stackup planning can help in the fight against radiated emissions. He also points out that many PCB designers lack a true understanding of EMC and radiated emissions in general, and why some knowledge of physics is so important to today’s PCB designers.

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

Well, William Shatner finally did the field research for his role as Captain James T. Kirk this week, going sub-orbital on the Blue Origin launch platform. No, I’m not making fun of Shatner’s flight, quite the contrary. He’s the first actor in the entire Star Trek franchise to go into space while still living. And at 90 years old, he’s now the oldest person to make the trip as well!

Tribal Knowledge and Design Data Formats

I recently began to investigate “tribal knowledge” in PCB and PCBA operations. My goal was to determine whether anything of value would be lost if it were not recorded or preserved for future industry technologists. In the face of modern material science and industry standards, the descriptive title “tribal knowledge” suggests that one must determine what is fact, what is fiction, and what may just be plain embellishment, coincidence, or even magic. In many cases, tribal knowledge seems to be composed of memories of problems solved due to trial and error, coupled with observations of resulting causes and effects.

Sunstone Circuits: Use the Design Data Format That Gives You Best Results

To get some feedback from a PCB prototype manufacturer about design data formats, we asked Matt Stevenson, Sunstone’s VP of sales and marketing, to weigh in. As Matt explains, his company is equally at home using Gerber or ODB++, but it’s not the fabricator’s job to convince customers to use one data format over another. In the end, you should use the format that gives you the best results.

Excerpt: The System Designer’s Guide to… System Analysis, Chapter 2

In Chapter 2 of this book, the subject involves the challenges in the design and development of data center systems.

Applying DFM Analysis to Flexible PCBs

Flex circuit designs have unique properties and materials that separate them from rigid printed circuit boards. The flex circuits’ thinness makes them more delicate, and they are more susceptible to accidental damage during manufacturing. This negatively affects the yield, increasing the per-item cost. Let us explore why running concurrent DFM is even more important with flexible circuitry than for rigid PCBs.


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

He also discussed the company’s increased efforts creating design education modules for customers who hire inexperienced PCB designers.


The Power of Designer and Manufacturer Collaboration

Whether you are beginning board layout, building the first run of a prototype, or you’re making a change to a mature product several years into its life span, there is no incorrect time to consult your PCB manufacturer. Circuit boards today are dense with features that push the limits of manufacturing technology, and as designers employ these technological advances it’s easy to venture off the well-documented path of standard manufacturing.

From DesignCon: Rogers’ Products at the Right Place and Time

Nolan Johnson recently spoke with Dean Marquart, product manager at Rogers Corporation about his role in managing parts so that customers are getting what they need—and when they need it.

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

The kids and grandkids are back in school, and fall is on the way. During this busy week, we published a variety of articles, covering everything from trade shows to mergers. It’s hard to argue with IPC’s plans to require proof of vaccine or a negative COVID test to enter IPC APEX EXPO; you can expect other trade shows to follow suit in the future. We’d hate for a show to become a super-spreader event.

Collaboration: The Key to Streamlining Your Design Process

We recently spoke with Patrick Davis, product management director of Cadence Design Systems, about the benefits of collaboration between PCB designers and fabricators—and the drawbacks to throwing designs “over the wall.” Patrick explains why designers and fabricators often seem to be talking past each other, the role that EDA software companies can play in facilitating collaboration, and why IPC-2581 may be the right means for connecting all of design’s stakeholders.

Seeking Out Design Education Resources

I’ve been doing PCB design for about 15 years. I started in high school, drawing out simple circuits in an image editor and raiding the local Radio Shack for ferric chloride and copper-clad boards for toner transfer etching. The results were crude, and often didn’t work, but the process was fascinating—and truthfully still is. For as empowering as it can be, PCB design has a shockingly low barrier to entry.

How to Use Panelization Planning to Save Money and Resources

My PCB Design Education: A Continuous Process

Being under pressure to deliver functioning boards, on time, made me aware of what could go wrong, and it forced me to employ a systematic approach to every design I work on. I started keeping notes of the tricks I learned along the way and because of that, I ensured that I wouldn’t make the same mistakes again. Here are some of the design practices that I’ve been following while designing boards.

Design Education and Training for Today and Tomorrow

PCB design and design engineering are evolving constantly, and design education and training must also evolve to meet the needs of tomorrow’s young designers—yes, there are young designers again. The I-Connect007 Editorial Team recently spoke about this issue with design instructor Susy Webb, CID. We asked Susy to discuss how design and training have changed in the last few decades, where design education is headed, and how today’s crop of new designers differs from the “graybeards” who are planning their retirements. She also recommends design education resources from a variety of media formats.

Ask the Experts: Why Are Fabricators Reluctant to Share Capabilities with Designers?

Q: No offense to your experts; I love your publication. But wouldn’t designers be better off posing questions to fabricators’ CAM departments? But they won’t answer them anyway! Which begs a question: Why don’t most fabricators share their capabilities, Valor settings, etc., with designers? And then they complain?

Siemens Webinar: Rigid-Flex Design Without Respins

Rigid-flex circuits have become almost ubiquitous over the past decade; most personal electronic devices contain at least one rigid-flex circuit. But there’s a downside to rigid-flex: Respins are almost a given with rigid-flex designs. And rigid-flex respins can be quite expensive, since this technology costs quite a bit more, on average, than flex or rigid boards.

Ask the Experts: Tying Vias

Q. What is the best method for tying vias to ground and power planes for bypass capacitors when using multiple caps of different values for one component power pin?

Anaya Vardya Discusses ASC’s Move into Additive Processes

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

This may be a global industry, but the effect is very real: holidays in the U.S. will drive the industry news cycle. In fact, I can even (unscientifically) rank the major U.S. holidays by their silencing effect on the news. Christmas leads the way, of course, followed by New Year’s, Thanksgiving, Independence Day, Memorial Day, and Labor Day. Here's a wrap-up of the biggest stories of the past week, starting before Independence Day weekend.

Ask the Experts: Crosstalk Solutions

Question: Crosstalk is getting worse, after we had it under control. It’s not just transmission lines anymore. It’s almost laughable, but it’s costing us money. What can be done?

It’s FR-4, Jim, But Not as We Know It!

As Star Trek was responsible for adding terms such as photon torpedo, dilithium crystal, and warp drive to our language, so NEMA were responsible for the terms G-10, FR-4, and FR-5. “FR” was the NEMA abbreviation for “flame retardant” and materials so classified were marked with a red manufacturer’s logo.

Star Trek: Laying a Path for Technology of Tomorrow, Today

In 1966, when Star Trek first aired, PCBs were in their infancy. A handful of components mounted to a double-sided board with 6-mil traces was on the leading edge of electronics. Since then, much of electronic innovation has been driven by PCB technology. Could the trends in PCB innovation have been predicted at that time? Perhaps through science fiction like Star Trek we can boldly explore our own final frontier.

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

Optimism is on the rise. This week, we saw signs of increased confidence in the PCB industry, but this was tempered by the realities of supply chain issues and 50-week lead times for some components. We saw some M&A activity and a bit of really interesting news from Stanford University about flex. Cherie Litson brought us a story of her life in PCB design, against a backdrop of Star Trek. IPC also announced an introductory PCB design class. Isn’t it nice to have new designers again?

This week, Nolan Johnson's top five includes two popular press releases on equipment purchases, plus a case study that details another company’s ROI from new equipment. We also bring you Pete Starkey’s latest EIPC webinar writeup, and a bit of historical controversy from Clyde Coombs.

Hewlett-Packard’s Adoption—and Controversy—of Plated Through-Holes

I believe that it is instructive to remember just how close Hewlett-Packard—and likely the entire industry—came to adopting eyelets instead of plated through-holes in the early 1960s. That there was ever a controversy over the use of plated through-holes as an acceptable printed circuit interconnection process seems almost impossible to consider, let alone take seriously today. But in the late 1950s and early 1960s, the PTH was not just a controversial idea; serious product designers considered eyelets a preferred technology.

EIPC Technical Snapshot Review: Microvia Reliability Issues

Since the mid-1990s, when they were developed for mass production in the mobile phone industry, microvias have become principal enablers for high-density designs, and have evolved from single-level to complex stacked and staggered structures. They are fundamentally robust interconnects, although some aspects of their reliability are still under investigation.

Star Trek, the Original Series: An Homage from a Fan

It’s fun to think back to the days when I first saw Star Trek on TV. In September 1966, I was a sophomore in college in chemical engineering. Being a science fiction fan for many years, I was looking forward to this new show, so I would go over to the student union building early in order to get a seat in the TV room. I got interested in science fiction from a few good movies like 20,000 Leagues Under the Sea (1954) and Forbidden Planet (1956). Then I took up reading the magazine Scientific American at the library.

The three top product failures that Ken Wyatt sees constantly in his consulting practice are radiated emissions, radiated susceptibility, and electrostatic discharge. After reviewing and testing hundreds of products over the years, he's come to the conclusion that products fail these tests for five common reasons. Read on!

PCB Design Challenges: Designing With DDR

Longtime signal integrity experts Rick Hartley and Barry Olney join the I-Connect007 Editorial Team for a discussion around DDR and the complications board designers inevitably face when they design for DDR. If, as Rick and Barry explain, the DDR design process is not that much more complicated than that of a typical high-speed board, why does DDR cause design engineers so much grief? Much of this comes down to following the process, running simulation, and not relying on reference designs.


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

Arlon President Discusses Acquisition by EMC

Arlon President Brad Foster updates Nolan Johnson on EMC’s acquisition of Arlon in December 2020. Foster shares the basic structure of the agreement, the long-term stability built into the merger, and outlines how this brings EMC, Arlon and Technica together as a team. Foster also hints at what we can expect to see from Arlon and EMC in the coming months.

A Tribute to Dieter Bergman

In 1962, while at Philco Ford, Dieter became the company’s official representative to the IPC. Dieter tag-teamed with his friend and co-worker Gerald Ginsberg on the development of a prolific run of technical publications including a multilayer design standard and the massive binder known as the IPC-D-330 IPC Design Guide. For his standards contributions, Dieter received the IPC President’s Award in 1968, the same year he assumed chairmanship of the IPC Design Committee.

Show & Tell Magazine Now Available on Demand

IPC APEX EXPO 2021 is in the history books now. But as the paperboys used to say in the 1930s, you can still “read all about it” in Real Time With… IPC APEX EXPO 2021 Show & Tell Magazine! It’s all right here in one convenient publication: interviews with award winners, coverage of keynote speeches, show notes from our technical staff, thoughts from IPC Emerging Engineers, and much more

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

This week’s biggest news came in the form of industry briefings—there were a lot of them and the news was universally positive. The news you need to read for this week includes three reports from IPC detailing: the strength and risks in the global economic recovery; a strong EMS book-to-bill ratio; and strong North American PCB sales. Zeroing in on a single company, Apple reported a significant jump in revenue.

IPC-2581 Revision C: Complete Build Intent for Rigid-Flex

With the current design transfer formats, rigid-flex designers face a hand-off conundrum. You know the situation: My rigid-flex design is done so now it is time to get this built and into the product. Reviewing the documentation reveals that there are tables to define the different stackup definitions used in the design. The cross-references for the different zones to areas of the design are all there, I think. The last time a zone definition was missed, we caused a costly mistake.

PCEA Expands in Its Sophomore Year

Andy Shaughnessy recently spoke with PCEA’s Scott McCurdy and Tomas Chester about the organization’s plans for its second year. They explained that they plan to add new chapters and members, especially younger engineers like Tomas.

Meet Chris Young, one of our newest I-Connect007 columnists! Chris’ columns will take a lighthearted (sometimes humorous) and informative view of the aerospace and defense industry.

A Show Full of Opportunities

Looking back to my notes from IPC APEX 2020, I noticed one of my comments: There were so many interesting sessions that I often found myself in the position of choosing between several that I wanted to attend in the same timeslot. This year was not any different in that regard. I am purposely glossing over the fact that I, like many of my friends, missed the camaraderie and opportunity to catch up in person while attending these technical sessions, and I look forward to being able to do that next year.

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

I’m sure it’s just me being hyperaware, but I can’t shake it: Mars is where it’s at right now. Is it just me, or do you get the same feeling from the news? There are the Mars rovers—three generations of them still rolling, now—and a drone helicopter winding up for a maiden flight any day now. But that’s not all. There’s SpaceX’s StarShip, rapid-prototyping its way into a manned flight to Mars. And NASA’s whole “return to the Moon” project is simply a shakedown for the U.S. government contractors’ Mars flight hardware, too.

Overcoming Component Selection and Sourcing Challenges

Most PCB designers know precisely how Captain James T. Kirk felt because we often feel the same way when starting a new design. We are launching into something that we ultimately don't know how it will turn out. We don't know the difficulties we'll face or problems we’ll need to fix. While we can control the design process and use our skills to make reasonable decisions, there are often huge hazards awaiting us in the "unknown." One worsening problem for all designers is component procurement.

Barry Olney’s High-Speed Simulation Primer

The I-Connect007 editorial team recently spoke with Barry Olney of iCD about simulation. Barry, a columnist for Design007 Magazine, explains why simulation tools can have such a steep learning curve, and why many design engineers are still not using simulation on complex high-speed designs.

Technical Conference—Balancing Conventional and Disruptive Technologies

I thought the three keynotes given by IPC President and CEO John Mitchell, Industry Week Editor-in-Chief Travis Hessman, and IPC Chief Economist Shawn DuBravac, were spot on. They all spoke to the fact that the way products are conceived, designed, manufactured, and used is changing rapidly. While the keynotes had different focus areas, I noted an important similarity—they all underscored the need for increased industry collaboration to help bring the factory and supply chain of the future to life.

With Flex, Sometimes You Gotta Break the Rules

Sometimes in life, we need to break the rules. For example, in junior high I had a curfew but to have my first kiss, I had to break curfew. I got grounded, but it was worth it! My last article was about reasons to follow IPC design and inspection rules. This time, we are discussing instances where, due to complex requirements, customers are not always able to follow the rules. I will also discuss some design options that will hopefully keep you from “getting grounded.”

Rising Star Award Winner: Radu Diaconescu

Last year’s IPC APEX EXPO, which took place in sunny San Diego, seems to have taken place in a different world. This was a world where talks were held in front of a large crowd, not a monitor, and travelling to the other side of the world wasn’t considered a reckless risk. By February 2020, however, we were starting to grasp the seriousness of the situation. Back then, there were a lot of things that we didn’t know, and more importantly, there were a lot of things that we had no clue that we didn’t know. The concept of “knowing what you don’t know” or figuring out the areas where one lacks knowledge is probably as important as acquiring the knowledge itself.

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

The Top 5 is labeled as “editor’s choice,” which is a good thing this week because if I were limited to just posting the five most viewed news items, this week’s list would be full of our own coverage for IPC APEX EXPO. Judging from the metrics, that content has been extremely popular.

Rooting Out an 'Us vs. Them' Mentality: An Interview with Laura Kriska

Earlier this year, I-Connect007 columnist Dan Beaulieu submitted a book review on "The Business of WE: The Proven Three-Step Process for Closing the Gap Between Us and Them in Your Workplace." As a follow up to that review, Dan has interviewed the book's author, Laura Kriska.

Happy’s Play-by-Play of IPC APEX EXPO

This was the first time IPC had a virtual APEX EXPO. It went well, but I missed seeing everyone. On the other hand, all this material being available for 90 days certainly allows it to fit anyone’s schedule. I spent all week intently listening to the presentations.

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

This week, we have a round-up of stories from around the industry, including a Real Time with… IPC APEX EXPO interview with Ventec, an article by Tamara Jovanovic about eliminating “garbage in, garbage out,” a review of an EIPC webinar by Pete Starkey, and news about another trade show going virtual this summer. And last but certainly not least, we bring you our one-minute video salute to all the fantastic people in this industry who we’ve worked with for decades. Enjoy!

Eliminating ‘Garbage In, Garbage Out’ With Checks and Balances

The proverbial saying “garbage in, garbage out” holds true in the electronic product development world. PCB designers stand squarely in the middle of a busy information intersection flowing with inputs and outputs. Missing or bad information at the beginning of a design project will undoubtedly lead to board re-spins, increased costs, and most importantly, a delayed product release. The same can be said about the PCB designer who doesn’t provide a fully checked and comprehensive data package to the downstream manufacturers, i.e., “throwing it over the fence.”

Averatek Offers Updates on ASAP Progress and Online Resource Site

Averatek’s Mike Vinson and Tara Dunn provide an update on Averatek’s ASAP progress. Mike shares the results from his presentation on reliability and signal integrity, while Tara details the newly announced ASAP Community of Interest web resource site.

I-Connect007 Video: A Salute to The Industry

I-Connect007 has produced this new one-minute video to acknowledge nearly 35 years of sharing your stories. In 1987 we launched our first industry publication and we have been dedicated to covering this industry ever since. We did not start out as publishers: in fact, our background was in printed circuit board fabrication. In 1987 there were still nearly 3,000 PCB shops in North America. At the time, profits were goods, trade events included giant industry parties (remember the extravagant hospitality suites in Anaheim?), and the industry was in a state of change.

DownStream Focused on Rigid-Flex and Embedded Component Support

Editor Kelly Dack and Joe Clark, co-founder of DownStream Technologies, discuss trends in PCB design and how this has led to the company's introduction of rigid-flex design support for their tools.

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

There was a lot going on in the industry this week, and most of it happened at the virtual IPC APEX EXPO. Sure, it wasn’t the same as being in San Diego, but the show went pretty well, especially for a first-time event. There were a few technical snafus, but the IPC technical staff was responsive and took care of most of the issues right away. As I said a few months ago, how would you like to be in trade show management during a pandemic? So, without further ado, here are my top five stories from the past week.

Elmatica Offers Unique Thank You for Dieter Bergman IPC Fellowship Award

This is how Norwegian PCB broker Elmatica said “thank you” to IPC for selecting Jan Pedersen for the Dieter Bergman IPC Fellowship Award. And you think you've had a cold winter! The Elmatica team definitely has a great sense of humor. Let's all congratulate Jan for his work with IPC, including updating PCB standards and helping to streamline the design data process.

Karen McConnell: Recipient of the IPC Raymond E. Pritchard Hall of Fame Award

"I heard about IPC when I started a new job at UNISYS after graduating college. I moved from ASIC design to printed circuit boards," said Karen McConnell after being inducted into the Raymond E. Pritchard Hall of Fame. "At the time, in the late ’80s and early ’90s, there were rumors going around that printed circuit boards were going to disappear, and ASICs were going to take over the world. But something in printed circuit boards fascinated me. I minored in robotics in college as an electrical engineer and the data used to fabricate, assemble and test the boards is actually all robotic language. I was hooked."


IPC APEX EXPO 2021 Keynote: Travis Hessman on ‘The Great Digital Transformation’

Wednesday’s Premier Keynote at IPC APEX EXPO 2021 came from Travis Hessman, editor-in-chief of IndustryWeek, “a website and magazine dedicated to manufacturing leadership, operational excellence and the technologies that make it possible.” An energetic and animated presenter, a powerful storyteller and visibly passionate about digital manufacturing, Hessman made it clear at the outset that his goal was not to hype an already over-hyped industry, nor to focus on the technologies themselves, but to walk-through the process of transformation.

Bonding Hybrid Multilayer Constructions at Rogers Corporation

John Ekis, Rogers Corporation's market segment director for aerospace and defense, discusses the SpeedWave family of low-dielectric constant, ultra-low-loss prepreg materials with excellent filling and bonding characteristics for hybrid multilayer constructions. SpeedWave prepreg is also compatible with FR-4 fabrication processes and lead-free PCB assembly processing.

In this presentation, Barry Maybank along with Naim Kapadia, MTC technology manager, explains the background of the MTC, one of seven high-value-manufacturing technology catapult centers established in the UK.

IPC APEX EXPO Keynote: John Mitchell on the State of the Industry

IPC President and CEO Dr. John Mitchell was the Monday keynote for the 2021 edition of IPC APEX EXPO. Delivered via video conference as a part of this year’s virtual format, Mitchell made good use of a panel approach. After opening remarks, Mitchell anchored an around-the-horn series of reports from IPC experts.

The Key to Eliminating Bad Design Data: Constant Vigilance

The I-Connect007 editorial team recently met with Jen Kolar and Mark Thompson of Monsoon Solutions to discuss ways to eliminate bad data from the design process, whether that be from CAD libraries, parts vendors, chip makers, or customers themselves. They key in on some problems and obstacles that allow incorrect data into the design cycle, and then highlight possible solutions.

IPC APEX EXPO 2021: The Complete Agenda

IPC APEX EXPO week kicks off today in a first-ever virtual format. The 24-page IPC APEX EXPO program of courses and conference events details the events, technical program, keynotes, and much more.

Virtual IPC APEX EXPO Kicks Off Today

There will be no long TSA lines, late flights, Uber rides, noisy hotel rooms, missing luggage, or aching feet...all things that we long for. Instead, we will be attending our first-ever online IPC APEX EXPO 2021 starting today. One key benefit with this year’s IPC APEX EXPO is your ability to choose what session you will see or not see, as the IPC will have the sessions available for 90 days after the show so that you can catch up on whatever you missed. Also, those on your team who normally do not travel to the event will now be able to take part.

The Magnitude of Stackup Considerations

When I was asked to write about stackup creation, I paused at the magnitude of this subject. It is similar to the framework used to pour concrete cement—you need to get the framework right because the framework has such a big impact on the final outcome. Such is the case with shaping the success or failure of our circuits. In writing the newest training manual due out early this year, I observed that the longest chapter in the textbook was dedicated to this subject.

Altium Introduces New Subscription Model

Andy Shaughnessy chats with Lawrence Romine about Altium’s new subscription model for their Altium 365 platform. They discuss what this means for existing and future Altium customers, and some of the drivers leading to this development, including evolving use patterns among customers during the pandemic.


Predicting a ‘Roaring Twenties’ Innovation Boom

The 2020s have not started as anyone would have wished. The COVID-19 pandemic has exposed weaknesses in supply chains and in global manufacturing, yet this could still be the most innovative decade ever.

Managing Footprints With Integrated EDA Tools

Electronics companies are always under great pressure to continually grow and innovate. In addition to navigating ever-accelerating design cycles, they must also address and overcome generational complexities associated with their products, the underlying components they use, and the human capital accountable for delivering on time and on budget. Electronics firms can ill afford the time and resource inefficiencies associated with manually correcting design errors, poor library data integrity, or other inconsistencies leading to missed deadlines or even costly re-spins.

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

I’m following the landing procedures for NASA’s Perseverance Mars lander as I’m finishing my Top 5 list for the week. The successful landing of the lander seems a nice highlight for this week. Our global aerospace programs, both national and private enterprise, make these missions seem almost, almost routine. They are, as we all know, anything but routine. No surprise, then, that aerospace-related news percolated to the top of mind for our readers this week.

Footprints: A Distributor’s Perspective

No issue on footprints and library management would be complete without input from a component distributor. I recently interviewed Geof Lipman of Octopart; as director of operations for part data, he’s one of the brains behind the entire site. Geof explains how Octopart functions and manages millions of component data points, and he also discusses the current landscape of electronic components.

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

We Are Stronger by What Unites Us

PCEA President Stephen V. Chavez and SMTA Global Executive Director Tanya Martin co-wrote this letter to the editor in response to a recent PCB007 column.

Joe Fjelstad's Book Review: The Innovators

"The Innovators: How a Group of Hackers, Geniuses, and Geeks Created the Digital Revolution" by Walter Isaacson is the best technology history book I have ever read, and at the same time one of the most engaging and entertaining. It is a forte of Isaacson to write biographies of great people. I have read his other books on DaVinci, Steve Jobs, Ben Franklin and Albert Einstein and found them equally brilliant. Isaacson has a number of other titles I have yet to get to in the future. He is a singularly great storyteller.

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

Another active news week in the electronics industry! February is launching with a high-G burn, to be sure. And if you’re a fan of The Expanse, like I am, then you’ve probably already watched through to the Season 5 finale; this means you have attention to spare for industry news all of a sudden. And if you haven’t reached the current end of the line for The Expanse, then today’s list is just what you need while you catch up.

Catching up With Nano Dimension

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

This week, we have a variety of news and articles to share, and it’s all positive. We have a new president, and he’s pledging to help American businesses. December PCB sales were up 4.5% over the same period a year ago. Atotech is just about ready to launch an IPO. Sunstone has tweaked its free CAD tool, PCB123, to make it even easier for designers to receive their Gerber files. And columnist John Watson breaks down what we all learned during the chaos that was 2020.


Book Review: The Timeliest Read of 2021—The Business of WE

It’s only January, but this may be the timeliest book of the year, as well as the most important. Why? Because it deals with the issues that we are facing right here now. The gap that Kriska refers to is the one between black and white, men and women and as the title suggests “we and them.”

IPC’s Alicia Balonek Talks Trade Show News

Nolan Johnson discusses IPC APEX EXPO 2021 with Alicia Balonek, senior director of trade shows and events at IPC. Alicia provides an update on how IPC APEX EXPO will be structured in a virtual format, overviews the programming changes, and new additions designed to make IPC APEX EXPO the best virtual event possible.

Book Excerpt: ‘Thermal Management: A Fabricator's Perspective,' Chapter 3

Conceptually, a metal-core board is exactly like it sounds—the metal is in the middle of the PCB sandwiched between layers on both sides. Just about any PCBA that will contain active heat-generating components can benefit when designed on a metal-core PCB. On a conventional PCB, the standard FR-4 layers are relatively poor thermal conductors, and heat is normally dissipated from active components using vias and thermal pads, as discussed earlier.

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

This week’s news gave off every indicator that we’ve started a new calendar year. The news channels were busy with changes in leadership—both corporate and governmental—and changes in ownership. Changes in representation, too. Honestly, it was hard to sort out the news to just five top items. Be that as it may, here are five things we think you ought to read, even if you read nothing else about the electronics manufacturing industry this week: tradeshow coverage, strategic acquisitions, market discussion, and governmental advocacy.

Your Greatest Competition is Yourself

It really doesn’t matter who you think your external competitors are, because the only competitor that really matters is you. Of course, you will look externally to stay on top of latest trends, but when it comes to competition, just competing with yourself is a win. When you look at yourself as your greatest competitor you will start with a huge advantage: you already have great intel on how “your competition” thinks. Ask yourself, “What can I do to displace my ‘competitor’ and create something much better?”

What’s Driving Price Increases for CCL and Prepreg?

Demand for copper foil is increasing from both PCB and battery production for e-mobility, leading to an upward price pressure for copper foils as post lockdown pent-up demand starts to exceed capacity. Lead times are stretching and prices increasing, particularly for heavy copper foils (2 oz./70 micron and above) as capacity is repurposed to maximize square-meter output for lightweight foils to increase capacity for lithium battery production.

Book Excerpt: Thermal Management With Insulated Metal Substrates, Part 5

The following is an excerpt from Chapter 5 of "The Printed Circuit Designer's Guide to... Thermal Management With Insulated Metal Substrates," written by Ventec International Group’s Didier Mauve and Ian Mayoh. In this free eBook, the authors provide PCB designers with the essential information required to understand the thermal, electrical, and mechanical characteristics of insulated metal substrate laminates.

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

Hard to believe that a year ago, I was getting ready to attend DesignCon and IPC APEX EXPO and wondering if this Novel Coronavirus was going to cut into attendance from the Pacific Rim. Now, we’re accustomed to virtual trade shows. They’re not ideal, but they’re the best we can do while meeting in person is not possible. We’ve learned to adapt.

TTM’s Approach to Stackup Design: Train the Customer

In this interview with the I-Connect007 Editorial Team, TTM’s Julie Ellis and Richard Dang drill down into stackup design, detailing some of the common stackup challenges that their customers face when designing for both prototype and volume levels, and offering advice to designers or engineers who are struggling with stackup issues. They also discuss why having too many different prepregs in a stackup can be asking for trouble, and how proper stackup design can optimize both the fabrication and assembly processes.

CES Dispatches: Opening Day at Pepcom

On Monday, January 11, I attended the launch of the CES 2021. Well, more precisely, I attended the Pepcom program, one of the multitude of ways to connect with CES in the virtual environment. Pepcom is a regular at CES, functioning a bit like a show-within-a-show.


CES 2021: Just How Different Will It Be?

CES 2021 starts today and this year there is no need for an overpriced hotel room in Vegas, no long lines to get a taxi or board a bus, and no crowded exhibit halls (one good thing this year). On the other hand, you must decide ahead of time what you want to see and make a reservation or appointment if you wish to have time and access assured.

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

It’s a new year, and time for new resolutions and new beginnings. “New year, new you” certainly is reflected in this past week’s news. We saw several announcements regarding mergers, acquisitions, and organizational changes, plus some government legislation to help kick off the new year. Based on viewing activity, readers were keen to keep up on the changes under way.

Cutting Respins: Journey to the Single-spin PCB

PCB design is more than a short sprint to the finish line; it is a journey best suited for the prepared adventurer. According to a study by Lifecycle Insights, the average PCB design project requires 2.9 respins. These respins can cost anywhere from tens of thousands to millions of dollars—each! As an engineer/business owner, I find respins frustrating because I would rather spend my time and money applying scientific principles inventing, improving technology, and solving problems. I am not an advocate for perfectionism, but rather I focus on becoming a better adventurer. Sometimes I get to taste the sweet wine that is a single spin PCB. As fellow adventurers, let’s discuss some topics that influence unnecessary return trips on our PCB design journey: simulation, technical reviews, and interest in PCB design.

IPC CEO and President John Mitchell Discusses New Membership and Dues Structure

In this video, IPC CEO and President Dr. John Mitchell discusses the organization’s move from a site-based and enterprise membership dues structure to a company revenue-based model. Mitchell explains that this change will go into effect upon each member company’s renewal in 2021, and he points out that many of the existing member discounts will remain unchanged.

Just Ask Heidi: The Most Rewarding Part of the Job

First, we asked you to send in your questions for Happy Holden, Joe Fjelstad, Eric Camden, John Mitchell, and Tara Dunn in our “Just Ask” series. Now, it’s Heidi Barnes’s turn! Today: the most rewarding part of a design engineer's job.

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

We always hear that the PCB industry is “mature,” full of people past their prime who don’t know how to change with the times. I think 2020 puts the lie to that idea. I’m honored to be a journalist covering such an amazing group of people. In the words of U2, “I will begin again.” Happy New Year!

I-Connect007 Wishes You a Happy New Year

Could there be a more welcome year in recent memory than 2021? If there’s one thing most of us can agree on, it’s that we want 2020 squarely in our rearview mirror as we speed ahead with a fresh, new start. This past year has brought with it much reflection, change and even some consternation. Thank you for taking this journey with us!

Just Ask Heidi: Attracting New Designers and Engineers

First, we asked you to send in your questions for Happy Holden, Joe Fjelstad, Eric Camden, John Mitchell, and Tara Dunn in our “Just Ask” series. Now, it’s Heidi Barnes’s turn! Today's question: How can we attract more young designers and design engineers to this industry?

Happy Holden Discusses His Favorite Career Moment

Managing Editor Nolan Johnson recently buttonholed Happy Holden and asked him to discuss the favorite moment of his career. To know Happy is to understand the full weight of his quiet influence on this industry. We’re delighted to share with you Happy’s reminiscence about spending time with his family at David Packard’s ranch while re-engineering the tank controls at the Monterey Bay Aquarium. As Happy explains, Packard may have been a billionaire and an ex-secretary of defense, but he still cleaned all of the fish that Happy’s kids caught on the ranch.


Lee Ritchey on Reducing Respins by One

I-Connect007 recently spoke with Lee Ritchey about the subject of continuous improvement with a focus on DFM, specifically looking at the benefits of reducing the number of respins by just one. A longtime instructor and one of the authors of Right the First Time: A Practical Handbook on High-Speed PCB and System Design, Lee has spent decades preaching the value of solid DFM practices, so we asked him to discuss why so many OEMs accept multiple respins with each design project and what designers could do to eliminate just one spin. He also shares some of the lessons in reducing respins that he learned in the early days of Silicon Valley.

Happy Holidays from I-Connect007

The I-Connect007 team would like to wish you and your loved ones the happiest holiday season. Continue to stay safe and healthy as we head into 2021. Happy Holidays!

IPC Addresses Critical Industry Skills Gaps With Electronics Workforce Training

Over the past three decades, IPC standards and certification programs have played a critical role in protecting public safety and promoting excellence by ensuring the quality, reliability, and consistency of electronic products. In 2019, IPC worked with its global network of certification centers to certify over 108,000 individuals across 200 countries and 21 languages to seven IPC standards. The ubiquitous adoption of these programs speaks to the strong partnership forged between IPC and the electronics industry.

Chapter 2 Excerpt from the Book ‘Thermal Management: A Fabricator's Perspective’

Insulated metal PCBs (IMPCB) or metal-clad PCBs (MCPCB) are a thermal management design that utilizes a layer of solid metal to dissipate the heat generated by the various components on the PCBs. When metal is attached to a PCB, the bonding material can either be thermally conductive but electrically isolative (IMPCBs or MCPCBs), or in the case of RF/microwave circuits, the bonding material may be both electrically and thermally conductive. The reason that RF designers usually have the bonding material thermally and electrically conductive is that they are using this not only as a heat sink but also as part of the ground layer. The design considerations are quite different for these different applications.

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

Some years, the middle of December is marked by a distinct lack of news in PCB design, fabrication and assembly. Much of the industry often takes off around this time to get a head start on the holidays, or to squeeze in a much-needed vacation. But 2020 is not one of those years. Most of us aren’t traveling anywhere farther than the refrigerator this year, and everyone seems to still be working, albeit from their home offices. And companies in the PCB community continue to make news.

Cadence’s Celsius: Don’t End up Holding the Hot Potato!

I was just thinking about the party game Hot Potato. It reminded me of today’s increasingly competitive marketplace: Accurate thermal analysis must be performed, and any potential issues have to be identified and addressed as early as possible in the design cycle. Otherwise the system will run into problems, market windows will be missed, and someone will be left holding the hot potato. Trust me, you do not want to be that someone.

Happy Holden: ECWC15 Virtual Event a Success

This is the first Electronic Circuits World Convention that I have not attended in person since 1978. To refresh your memory, these are held every three years on a rotating basis. The HKPCA hosted this year’s conference and they kept up the fine tradition of collecting outstanding keynotes, nearly 60 technical presentations and myriad poster papers. HKPCA was also kind enough to provide English slides and translations. It is still possible to sign up and view the presentations. I have listened to 20 of the presentations, and hope to attend even more in the coming days as they are all worth watching.

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

This week’s mainstream news was dominated—well, my personalized online news feed was, at least—by ballistics. SpaceX was in the news daily for lobbing multiple pieces of iron, even as their CEO took his household suborbital, leaving California and touching down in Texas. Pandemic numbers charts continue their skyward trajectory worldwide. The ever-present military tests and technology demonstrations, seemed a bit more commonplace this week as well. Worldwide political news, in general, seemed to follow parabolic curves like an Australian boomerang, veering off in unexpected ways only to suddenly cut a curving path and return.

Chapter 1 Excerpt from the Book ‘Thermal Management: A Fabricator's Perspective’

Heat cannot be efficiently exchanged with stagnant air surrounding a hot device; however, it can be transferred away from the electronic component to the PCB using thermal vias. A thermal via is a good conductor of heat that runs between the top layer and bottom layer of the PCB, dissipating heat through simple conduction. In simple terms, thermal vias are plated holes located under, or electrically connected to, a surface-mounted heat source on a PCB that allows heat transfer through the hole.

Documenting Your Flex Circuit Design

As a flex circuit applications engineer, when I receive an RFQ, the first thing I do is look at the customer’s data and review their manufacturing notes. Quite often, I find notes that supersede IPC specifications in manufacturing documents, as customers often believe these added notes and associated specifications will make the circuit more robust. However, these non-standard IPC manufacturing specifications/notes can wreak havoc on the manufacturing process and can actually lead to a less robust circuit.
