What is a return current, and how does it affect a PCB circuit?
Your prototype passes every test on the bench, but fails EMI compliance. Worse, it has intermittent failures in the field. You’ve checked every component, but the mysterious glitches and noise persist, threatening your entire project timeline. The culprit is often a misunderstood return current; let’s master its behavior to build truly robust designs.
