Connect the Dots: Designing for the Reality of UHDI PCBs—Drilling

October 30, 2025 | Matt Stevenson, Connect the Dots

Ultra 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.

Have you ever noticed how high-speed design and signal integrity classes are always packed to standing room only, but just down the hall, the session on power electronics has plenty of empty chairs? It's not just a coincidence; it's a...

The Shaughnessy Report: Watt About Power Integrity?

October 8, 2025 | Andy Shaughnessy, The Shaughnessy Report

Yes, 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...
