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

Many engineers still think electricity flows like water.

If that were true, ESD would be easy.

Just add conductors.

Direct the discharge to the ground.

Problem solved, right?

Wrong.

Tried fixing ESD this way?

You’ve learned the hard way.

The Grounding Lie:

Many believe earth ground stops EMI.

It doesn’t.

In fact, it can make things worse.

Much worse.

The Right Approach?

To fix ESD, think in energy.

Start with fields and propagation.

Yes, you need to understand displacement current.

Then it all clicks.

Simple. Not Easy.
