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?
Time for a Price Hike?
If you manage a fabrication facility, we don’t envy you. You’re being hit on all sides with price increases, you’re traditionally leery of raising your own prices, but you must do something. Do you raise prices, trying to squeeze out more efficiency, or is it some combination of both? We asked Prototron President Dave Ryder and I-Connect007 columnist Dan Beaulieu to share their thoughts on the current fab pricing environment, the need for greater cooperation, and some pricing strategies for fabricators who are nervously eyeing their bottom line.
Catching Up With NEXTGEN’S Ravi Kumar
Companies from India are becoming more sophisticated by providing complete engineering services as well as design, production, and assembly of printed circuits. In this conversation with Ravi Kumar, director of operations at NEXTGEN PCB, I learned that even though the company is only a few years old, it’s already making its mark in the industry. Ravi has a plan to not only expand in India, but to enter the U.S. and UK markets with his company’s services.
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.
Today’s M&A: Right on Target
In this enlightening conversation with M&A specialist Tom Kastner, Nolan Johnson learns that it’s a buyer’s market—and a seller’s market too.

Printed Circuit Boards: Past the Lobby and Onto the Floor
There has not been a time in recent memory when the U.S. legislative body is putting as much focus on the microelectronics industries. One bill, the CHIPS Act, was signed into law last year. A new bill introduced this year seeks to allocate funding for printed circuit board fabrication. In this exclusive interview, our team spoke with Travis Kelly, CEO of Isola Group and president of the Printed Circuit Board Association, and U.S. Rep. Blake Moore (R-Utah), who has co-sponsored the bill now before the House. Travis and Blake both express optimism about onshoring domestic production, but the realities of the legislative calendar may pose some risks.

With his knowledgeable insight into the business and technology of the printed circuit industry, Dr. Shiuh-Kao Chiang, managing partner at Prismark Partners, has put a global perspective on the challenges of the 2022 PCB market. His presentation at the EIPC Summer Conference in Orebro, Sweden, on June 14 was eagerly awaited by an attentive audience, keen to share his vision. From his comments, it was clear that 2022 will be an interesting year and does not appear particularly friendly for the PCB business.
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.
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.
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.
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.
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.

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.
A Primer on M&A With Tom Kastner
Tom Kastner of GP Ventures is a busy man these days. He’s been involved in several M&A deals, including a recent acquisition by Summit Interconnect. Tom spent some time with Dan Beaulieu, who often consults with PCB and PCBA companies, about what it looks like when a company is thinking of buying or selling—and how a consultant like Tom helps negotiate the best deal.
IPC Mexico Continues to Grow
IPC Mexico has been growing for the past few years, and it’s no wonder: Mexico has become a major hub in the world of PCB manufacturing, spurred in part by reshoring as companies pulled work back from China during the pandemic. As the country’s maquiladoras thrived, IPC began expanding the Mexican educational and training operations, and the group recently named Lorena Villanueva as director of IPC Mexico. Andy Shaughnessy and Barry Matties recently spoke with Lorena and IPC Vice President of Education David Hernandez about IPC Mexico’s growth, as well as the office’s plans to provide PCB manufacturers the training resources they need to succeed.
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.
Catching Up with Prototron’s Lee Salazar: Sales in the New Frontier
In the business world, salespeople arguably were the most affected by the pandemic. These professionals had to be the most creative when trying to ply their trade. They had to work from home, make phone calls in lieu of face to face, and learn how to use social media networks and newsletters. This was all to reach their customers—who also were working from home. Even when they got vaccinated and managed to hit the road, they often found that their customers’ doors were closed and they were not allowed inside, if their particular contact was there at all. Many times, they had to resort to meeting their customers in parking lots or restaurants with outdoor dining. And guess what? It’s not even over yet. So, how does a salesperson create success when so much seems to have changed? I reached out to Lee Salazar of Prototron to learn how he met the challenges, and his tips for others who are moving forward.
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.
Plating on Silver: What’s Old is New Again
About three decades ago, immersion silver, a nitrate-based process, gained a lot of market share in the world of PCB final finishes. More economical than ENIG, flat, solderable, and conductive, it had everything going for it—everything but corrosion resistance in a harsh environment, that is. Champagne voids were also an issue, along with line reduction. But the worst drawback, the characteristic that made the part short over time, was creep corrosion. A build-up of copper sulfide salt that grows in contact with a sulfur-rich environment, heat, and moisture resulted in failures in the field. This was enough to scar the process for good.
