Current IssueRules of Thumb
This month, we delve into rules of thumb—which ones work, which ones should be avoided. Rules of thumb are everywhere, but there may be hundreds of rules of thumb for PCB design. How do we separate the wheat from the chaff, so to speak?
Partial HDI
Our expert contributors provide a complete, detailed view of partial HDI this month. Most experienced PCB designers can start using this approach right away, but you need to know these tips, tricks and techniques first.
Silicon to Systems: From Soup to Nuts
This month, we asked our expert contributors to weigh in on silicon to systems—what it means to PCB designers and design engineers, EDA companies, and the rest of the PCB supply chain... from soup to nuts.

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.”

Rules of Thumb for PCB Layout
11/21/2024 | Andy Shaughnessy, I-Connect007The dictionary defines a “rule of thumb” as “a broadly accurate guide or principle, based on experience or practice rather than theory.” Rules of thumb are often the foundation of a PCB designer’s thought process when tackling a layout. Ultimately, a product spec or design guideline will provide the detailed design guidance, but rules of thumb can help to provide the general guidance that will help to streamline the layout process and avoid design or manufacturing issues.

Flexible Thinking: Rules of Thumb: A Word to the Wise
11/20/2024 | Joe Fjelstad -- Column: Flexible ThinkingIn the early days of electronics manufacturing—especially with PCBs—there were no rules. Engineers, scientists, and technicians largely felt their way around in the dark, making things up as they went along. There was a great deal of innovation, guessing, and testing to make sure that early guidelines and estimates were correct by testing them. Still, they frequently made mistakes.
