Tons of electronics fail EMC tests. They’re missing this essential.

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.
