Beyond Design: Slaying Signal Integrity Villains

September 17, 2025 | Barry Olney, Beyond Design

High-speed PCB design is a balancing act, where subtle oversights can develop into major signal integrity nightmares. Some culprits lie dormant during early validation, only to reveal themselves later through workflow disruptions and elusive performance bottlenecks. Take crosstalk, for example. What begins as a stray signal coupling between traces can ripple through the design, ultimately destabilizing the power distribution network. Each of these troublemakers operates with signature tactics, but they also have well-known vulnerabilities.

Staying on Top of Signal Integrity Challenges

September 16, 2025 | Andy Shaughnessy, Design007 Magazine

Over the years, Kris Moyer has taught a variety of advanced PCB design classes, both online IPC courses and in-person classes at California State University-Sacramento, where he earned his degrees in electrical engineering. Much of his advanced curriculum focuses on signal integrity, so we asked Kris to discuss the trends he’s seeing in signal integrity today, the SI challenges facing PCB designers, and his go-to techniques for controlling or completely eliminating SI problems.

The Shaughnessy Report: Winning the Signal Integrity Battle

September 9, 2025 | Andy Shaughnessy, The Shaughnessy Report

When I first started covering this industry in 1999, signal integrity was the hip new thing in PCB design. Conference classes on signal integrity were packed to the walls, and an SI article was guaranteed to get a lot of...

Connect the Dots: How to Avoid Five Common Causes of Board Failure

September 4, 2025 | Matt Stevenson, Connect the Dots

Boards fail for various reasons, and because I’ve been part of the PCB industry for a long time, I’ve seen most of the reasons for failure. As part of my ongoing crusade to help designers design for the reality of manufacturing,...

Rigid-flex PCBs come in all shapes and sizes. Manufacturers typically use fire-retardant, grade 4 (FR-4) materials in the rigid section and flexible polyimide materials in the flex region. Because of the small size, some rigid-flex...
