Current IssueBreaking High-speed Material Constraints
Do you need specialty materials for your high-speed designs? Maybe not. Improvements in resins mean designers of high-speed boards can sometimes use traditional laminate systems. Learn more in this issue.
Level Up Your Design Skills
This month, our contributors discuss the PCB design classes available at IPC APEX EXPO 2024. As they explain, these courses cover everything from the basics of design through avoiding over-constraining high-speed boards, and so much more!
Opportunities and Challenges
In this issue, our expert contributors discuss the many opportunities and challenges in the PCB design community, and what can be done to grow the numbers of PCB designers—and design instructors.

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.

If you’re trying to make a PCB that stands out for being reliable, easy to manufacture, and meets all design goals, then you’re in the perfect spot. We’re here to break down the PCB manufacturing process while sharing essential tips for smooth design and production.
Elementary, Mr. Watson: Pushing Design Boundaries
05/29/2024 | John Watson -- Column: Elementary, Mr. WatsonOverconstraint: What a concept. Our first thoughts would be: What are we hurting by overconstraining a design? Isn't it better to be safe than sorry? What is meant by overconstraint? It means to apply excessive constraints. In engineering and mathematics, it's used when there are too many simultaneous equations to result in an exact solution. For example, fitting a line to many points is overconstrained because a line cannot be drawn simultaneously through all of the points. In PCB design, overconstraints always occur, including dimensional, electrical, manufacturing, and timing constraints. The list goes on.
