EMI Bites: How to Reduce Crosstalk in Densely Packed PCB Designs?
The problem is that sometimes we might not have enough space to increase the distance between signal traces, but we still need to reduce crosstalk.
So, how can we tackle this?
Stackup.
Yes, to minimize the effect of fringe fields spreading outward from the signal traces, we can reduce the distance between the signal trace and the return/reference plane.
This allows for greater coupling between the layers and keeps the fields contained and channeled.
It's a simple and sometimes inexpensive fix that we can implement before even producing the board.
Because yes, EMI is not a last-minute thought, and it's definitely not black magic.
