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

It’s an easy trap to fall into—but there’s a simpler way.

If you’d like your electronics to pass EMC tests without all the back-and-forth, try picturing electromagnetic fields instead.

Here’s what’s helped me:

- What are signals when you see them as EM fields?

- How do they move through your PCB?

- How can you guide them with the stackup?

No need to overcomplicate things.

You don’t have to dig into Maxwell’s equations…

For now, at least! :)

Just start with the basics:

🔹 Electric field

🔹 Magnetic field

🔹 Impedance

🔹 Conduction current

🔹 Displacement current

Get a feel for these, and you’ll set yourself up for smoother designs and fewer headaches.

EMI isn’t black magic.
