GROUNDED: EMC/EMI & PCB Design Nuggets

Traces get routed to redirect electrons, not EM fields.

Stackups follow the “cheapest, fewest layers” rule.

The result? Uncontrolled fields radiating chaos.

Look at the left: fields spreading everywhere, untamed.

EMC instruments spot that mess and fail you instantly.

Now check the right: fields contained, behavior predictable.

That’s what passes EMC every single time.

The fix is simple but non-negotiable.

How many engineers still think EMI is black magic?

Imagine this holding you back from the next level.

Simple fundamentals, applied all wrong.

Bad news: if you’re still failing EMC, you’re stuck in this loop.

Good news: they’re easy to fix once you know them.
