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.

Catching up With Kusu’s Pascal Delloue

There are other countries in Asia besides China and Pascal Delloue intends to promote them. He has many years of experience in the global marketplace and his new company, Kusu Corporation, is poised to introduce SE Asian companies and the electronics products they can provide for the rest of the world. I have to say this is an interview like no other I have ever conducted. Read on and you’ll see what I mean.

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

In case you’ve been on the beach with an umbrella drink in your hand, in industry news we saw the soft opening of a new laminate facility and more M&A activity in the PCB fab segment. And we ran some really great content from our contributors, with articles on how to save your company money and how to save yourself time in the design cycle. Plus, Editor Nolan Johnson channels his inner John Updike with his review of one of the most popular manufacturing strategy books ever, three decades after its publication.

My Ongoing Journey Toward DFM

For the past five years I have spent the first several hours of each working day communicating with a wide variety of offshore manufacturers about customer PCB design issues. I must say, it has been an eye-opening experience. Not only have I learned a lot about PCB manufacturing capabilities and challenges around the world but also about the design for manufacturability (DFM) attitude and aptitude of a wide cross-section of North American PCB designers and design engineers.

Planning and Communication—Key to Optimizing Your Design Time

How many times in our careers have we been asked, “Can we pull in the schedule?” and we can feel the hair on the back of our neck standing up on end. This type of question can be hard to hear simply because it is the wrong type of question.

PCEA Webinar: Tips and Tricks for RF Design

Dan Feinberg recently attended a remarkably interesting presentation on tips and tricks of designing for RF signals, hosted by the Printed Circuit Engineering Association. If you’re not yet familiar with PCEA, it is made up of former members of the IPC Designers Council, and it has become an international network of engineers, designers, fabricators, assemblers, and anyone else related to printed circuit development.

Why You Should Get Involved in IPC Standards Development

From a business perspective, involvement in IPC standards is incredibly important. Usage of IPC’s globally accepted standards creates a level playing field in the electronics supply chain. The playing field, however, is only as level as the participants who are involved in the development of a standard.

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

Summer is almost upon us. But it doesn’t look like there’s much of a summer vacation afoot for this industry. In the past week, we saw lots of traction with our coverage of everything from M&A activity and the supply chain shortage to challenges facing PCB designers, Spanish language training courses, and designing for semi-additive processes.

Operational Excellence from a Design Services Manager

Jesse Vaughan discusses the key aspects of continuous improvement he sees in his role as manager of design services at ACDi, and the importance of carving out communication channels—both internally and externally to help build operational excellence.

Medical, Defense Face Shortage of Multilayer Ceramic Capacitors

Industrial, medical, and military demand for high-quality, high-voltage multilayer ceramic capacitors (MLCCs) has been hit hard by a shift in production by the world’s largest MLCC manufacturers who are focusing on a seemingly insatiable demand for smaller, lower voltage—and in some way—lower-performance MLCCs.


Meeting the Challenge With Design Reuse

As project schedules get shorter and budgets get squeezed, project managers and small business owners must constantly look at ways to maximize limited funding and resources. But reusable PCB design IP allows us to investigate ways to potentially shorten design cycle time.

The Top Five Reasons Products Fail EMI Testing

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

And our industry is on the move! This week, we bring you a veritable seafood platter of articles and columns about PCB design, fabrication, and assembly.

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.

Hate PCB Respins? Five Ways to Reduce or Eliminate Respins

Redesigning a printed circuit board is a chore that no one likes. Respins of printed circuit boards cost money, delay the schedule, and just aren’t enjoyable for anyone. Yet, many companies are not taking advantage of available tools that can reduce—and in many cases eliminate—PCB respins.

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.

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.

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.


Why We Simulate

When Bill Hargin was cutting his teeth in high-speed PCB design some 25 years ago, speeds were slow, layer counts were low, dielectric constants and loss tangents were high, design margins were wide, copper roughness didn’t matter, and glass-weave styles didn’t matter. Dielectrics were called “FR-4” and their properties didn’t matter much. A fast PCI bus operated at just 66 MHz. Times have certainly changed.

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.

Benchmarking Your Process Engineering

Mark Thompson has been in bare board fabrication for over 30 years. He is now laying out printed circuit boards at Monsoon Solutions, a high-tech design bureau near Seattle, Washington. With Mark’s extensive hands-on knowledge of PCB manufacturing, he brings a unique perspective to PCB design. In this discussion with the I-Connect007 editorial team, Mark shares what’s important from a process engineer’s point of view, and how to stay on top of evaluating and benchmarking your manufacturing process, along with insights from his new role as a designer.

DFM 101: PCB Materials

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

Isola Releases IS550H Material

Nolan Johnson speaks with Michael Gay of Isola and Chris Hunrath of Insulectro about the release of their new halogen-free, high-thermal reliability material, which they hope fills the gap in the market between epoxies and polyimides.

Alternatives to Simulation

We are living in an age where the demands on electronic product designs are constantly evolving. The IC technology and operating speeds continue to pose significant challenges for teams as they work to develop their products. The increased transistor switching speeds and less forgiving compliance standards make signal integrity and electro-magnetic compliance more difficult to achieve. The status quo seems to have become, “We expect to fail EMC testing.”

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

Nolan Johnson and Happy Holden speak with Sarah Czaplewski, whose team at IBM won the Best Technical Paper award at this year’s IPC APEX for “Signal Integrity, Reliability, and Cost Evaluation of PCB Interlayer Crosstalk Reduction.”


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.

Excerpt—The Printed Circuit Assembler’s Guide to... SMT Inspection: Today, Tomorrow, and Beyond, Chapter 2

A limitation of many 3D optical inspection systems is the cycle time typically associated with processing millions of pixels to reconstruct a full 3D image using data captured from multiple channels. There should not be a compromise between 3D inspection and throughput. A successful inspection deployment should provide oversight for the process, not compromise, interrupt or slow that process.

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.

Bridging the Simulation Tool Divide

Todd Westerhoff of Siemens EDA recently spoke with the I-Connect007 Editorial Team about the divide between users of high-powered enterprise simulation tools and those who need a more practical tool for everyday use, and how Siemens is working to bridge the gap. Todd also shared his views on why so many engineers do not use simulation, as well as advice for engineers just getting started with simulation tools.

My Thoughts From the Virtual Show

Gosh, I sure missed the live event! I listened in on several technical sessions, the awards ceremony, the keynotes, and the Hall of Fame management session. I tried a couple of professional development courses but got the frownie face on my screen and didn’t go back in. I have almost 90 days(!) to browse them to my heart’s content, so what the heck. There were good points and a few not so good things about this first ever virtual conference. You probably experienced some yourself.

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

In this week’s roundup, we have news about a new DFM environment from Siemens EDA, a 2D field solver from Avishtech, and a milestone for the IPC-CFX-2591 QPL. We also have a great article by Calumet’s Audra Thurston, who points out the many advantages of a virtual trade show. And in his latest column, Denny Fritz explains why the DoD is now thinking like many U.S. OEMs—worrying about single-source components, for instance—but the stakes are much higher.

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.

Polar Instruments Driven by Customer Demand

Andy Shaughnessy recently spoke with Geoffrey Hazelett, vice president of sales for Polar Instruments, about the virtual IPC APEX EXPO and the eventual return of live trade shows and conferences. They also discussed some of the company’s newest releases, many of which came about through customer demand.

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

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.”

EIPC Technical Snapshot: 5G and Loss Minimisation

Bringing a specialised technical area into sharp focus, this month’s topic was “5G and the understanding of loss minimisation at the PCB level,” with papers on dielectric material, copper foil, and modelling solutions. The webinar was moderated by EIPC board member Paul Waldner managing director of Multiline International Europa, who admitted that he had managed to get a haircut especially for the occasion!

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.


Turning ‘Garbage In, Garbage Out' into ‘Good In, Good Out’

In the PCB design cycle, it is so easy to unintentionally introduce “garbage” into your system. Unless you have time to extensively check everything you bring in from an external source, it is very likely that something will not match up with your design data. In the end, this means you’ll have to put more work into your design and basically reverse-engineer a part that was supposed to save you time and effort.

Achieving Growth in a Difficult Year: The Benefits of Global Supply Chain Management

Jack Pattie, president of Ventec USA, discusses the growth of the business, the strengthening of the operation, quality system accreditations, the advantages of building close working relationships with OEMs, and how a well-managed global supply chain has overcome some of the challenges and frustrations encountered during the past year.

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.

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

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.
