The Signal Integrity Issue: Design007 Magazine September 2025
September 9, 2025 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute
During the dotcom boom, SI seemed a lot like black magic. Until then, PCBs ran at such low speeds, and rise and fall times were so long, that designers didn’t have to worry about “analogish” behavior. You could ballpark it and get away with it.
Today’s PCB designers have far more weapons to wield in their fight for SI than they did in 1999. That’s a good thing, because almost everything on a board is faster, smaller, and more complex than a few decades ago. As the saying goes, “If you don’t have signal integrity problems now, you will eventually.”
This month in the September issue of Design007 Magazine, our experts share a variety of design techniques that can help PCB designers and design engineers achieve signal integrity.

Connect the Dots: Designing for the Reality of UHDI PCBs—Drilling
11/04/2025 | Matt Stevenson -- Column: Connect the DotsUltra high density interconnect (UHDI) PCBs are changing the game in designing for the reality of manufacturing. With both consumer and industrial electronic devices becoming more advanced, the demand for UHDI PCBs will grow. That means we’re all likely to be designing more UHDI boards. UHDI advanced miniaturization technology challenges designers with regard to both board thickness and footprint. Designers will face more variables in every aspect of design creation. This is certainly the case with drilling.
The Shaughnessy Report: Watt About Power Integrity?
10/08/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportYes, that headline is the equivalent of a dad joke, but editors can’t pass up a chance to inject a little humor into a headline, and I had to take my shot. Power integrity (PI) problems are no joke. Current power demands are increasing, especially with AI, 5G, and EV chips, which can lead to voltage drops that kill your performance.
New Fil Arzola Class: Designing for the Future, and for Sustainability
10/07/2025 | Andy Shaughnessy, I-Connect007If you have not yet taken a class from Fil Arzola, you are missing out. In late October, Fil will be teaching the class "Building Sustainable Model-Based PCBs," speaking from the design perspective. I had the pleasure of catching this course at last year's IPC APEX EXPO, and I walked away with a lot to think about. I asked Fil to discuss his upcoming course. Registration is open now.
