GROUNDED: Your PCB, EMC/EMI, and SI Nuggets

🔹 Do all signals, especially those on surface layers, have a continuous, low-impedance return path underneath them?

🔹 Have you minimized asymmetries between differential pair signals?

🔹 Have you placed filters and protections on all external I/Os?

🔹 Have you stitched all return reference planes ("grounds") to minimize plane resonance?

🔹 If you’ve used power planes, are they adjacent to the return reference plane and as close together as possible?

Will this guarantee you’ll pass EMC tests?

Not quite, there are more variables at play. But this is a great start.

Not sure if your PCB design will pass the next EMC test?
