Connect the Dots: Designing For The Reality of UHDI PCBs - Drilling

As devices get smaller and more powerful, UHDI (Ultra High Density Interconnect) PCBs are quickly becoming part of everyday design. But with all that advanced miniaturization comes a new set of challenges—especially when it comes to drilling.

Drilling may not sound exciting, but in UHDI design, it can make or break your board. From via size and material selection to overall stack-up and thickness, every detail matters.

If you’re starting to design UHDI boards (and chances are you will be soon), this article breaks down what you need to watch for—and how to avoid the costly drilling mistakes that can derail a project.

Key takeaway: UHDI design demands precision—especially in drilling. Small choices in vias, thickness, and materials can make or break performance.
