90% of EMC test failures come from ONE tiny mistake—and it’s hiding in your circuit board design.

For example: Run a signal line over a gap, and you’ve just made a potential EMI mess.
I missed this too until I started wondering:
🔹 What happens when the signal hits that gap?
🔹 Can the energy between the layers go wild?
🔹 What if those layers connect to cables and blast interference everywhere?
These aren’t just “what ifs”—they’re hidden problems your schematic drawings won’t show you.
Learn the fundamentals: fields, impedance, currents
and you can stop them before they cost you big time.
Passing EMC tests comes down to preparation, not chance.
