I-Connect007 Editor’s Choice: Five Must-Reads for the Week
April 5, 2024 | Andy Shaughnessy, I-Connect007Estimated reading time: 3 minutes
Spring has definitely sprung; it was 81 degrees last week in Atlanta, and this week it’s been in the 40s. That’s typical spring weather in Atlanta. My newly cut lawn is looking great, thanks to my “yard guy” Clive.
And now our industry’s trade show season is in full swing. I’m all checked in and heading to Anaheim to cover IPC APEX EXPO next week. There’s a lot going on there this year, especially in PCB design. The number of design-related conference classes continues to grow with each show. That’s a good thing: New designers are entering the workforce, slowly but surely, and many companies are losing their subject matter experts to retirement.
IPC APEX EXPO will be held in Anaheim for the next couple of years. The last time I attended in Anaheim was about 20 years ago, and I never did make it to Disneyland. I’m shooting for some Mouse time this year.
I need to finish packing, so without further ado, here’s my must-reads for this week. I hope to see you in California.
Tim’s Takeaways: The Art of Technical Instruction
Published April 4
Speaking of PCB design, do you have what it takes to be a design instructor? You might. As columnist Tim Haas explains, there’s a need for design instructors, and if you’re constantly doing research and reading the latest white papers, you might be a great candidate for a design instructor. He also provides a few horror stories from his design teaching days. Check it out.
Creators of SMT UHDI Test Board Vehicle Discuss this Important Project
Published April 4
Chrys Shea led the development of the SMT test vehicle a few years ago. As features continued to shrink, the industry saw a need for a UHDI test vehicle, so Chrys and Altium’s David Haboud sprang into action. In this audio interview, they discuss what it took to update the test vehicle to UHDI and why technologists working in UHDI should check it out for themselves.
Global Sourcing Spotlight: Don’t Be Afraid of Global Sourcing
Published April 3
No matter how good things are going, some of us have this nagging suspicion in the back of our minds that there’s another snafu waiting around the corner, and another supply chain shutdown probably ranks Numero Uno in that category. But as columnist Bob Duke explains, despite two shooting wars and our stressful relationship with China, global sourcing is not only looking solid—it actually might help bring nations closer together and stave off potential conflicts. As he says, “Business is all about people.”
Checking In With ICAPE Group
Published April 3
ICAPE operates in countries around the globe, from China to South Africa to the U.S., so the company has a pretty broad view of the fab industry. In this interview, ICAPE’s Erik Pedersen explains how they approach sustainability, what sustainability actually entails, and why value engineering is so critical.
IPC APEX EXPO 2024: There’s an App for That
Published April 3
If you’re heading to IPC APEX EXPO, you’ve probably noticed that there are so many classes and “special events” taking place, often at the same time. Make it easy on yourself and scan this handy-dandy APEX QR code, and you’ll be able to see each day’s events at a glance while getting alerts for the events that are most important to you.

Everyone’s Talking About Power
11/06/2025 | Heidi Barnes, Keysight TechnologiesDelivering power to a digital load is an AC function, not DC. That simple statement may be obvious, but the implications of how electricity travels to an electronic load are complicated. Dynamic loads with rapidly changing currents create electric and magnetic fields that adhere to Maxwell’s equations. Ground can be misleading and is probably better used for describing where one grows potatoes and carrots. Electrical currents have “return paths,” and the energy is traveling in the fields between the power rail and the return path.
New Podcast Episode: “Bonding Innovation: How Adhesives and Coatings Are Powering the Next Generation of Electronics”
11/05/2025 | I-Connect007I-Connect007 has released of a new episode in its Voices of the Industry podcast series, titled “Bonding Innovation: How Adhesives and Coatings Are Powering the Next Generation of Electronics.” Hosted by Nolan Johnson, this insightful discussion dives deep into the evolving world of adhesives and coatings—materials that are redefining performance, reliability, and design in modern electronics manufacturing. Dymax's Doug Katze, a leading expert in adhesive technologies, delivers what can only be described as a master class on how these critical materials are adapting to meet rapidly changing market demands.
Target Condition: Distribution of Power—Denounce the Ounce
11/05/2025 | Kelly Dack -- Column: Target ConditionHave you ever wondered why the PCB design segment uses ounces to describe copper thickness? There’s a story behind all of this—a story that’s old, dusty, and more than a little absurd. (Note that I didn’t add “Like many of us.”) Legend has it that back in the days of copper tinkers and roofing tradesmen, the standard was set when a craftsman hammered out a sheet of copper until it weighed one ounce, when its area conveniently matched the square of the king’s foot.
