← Back to context Comment by stavros 5 days ago Excellent, thank you. I already do the plane, but not the caps. Thanks! 1 comment stavros Reply ted_dunning 5 days ago Based on seeing lots of beginners (me, too, at one time) do ground planes wrong, this video may help:https://www.youtube.com/watch?v=EEb_0dja8tE&t=746sHans Rosenburg explains some tricky concepts very clearly. The upshot isa) 4 layer boards are much easier to get rightb) you really need an unbroken ground plane for return currents. This is often incompatible with having just two layers.c) putting the ground plane much closer to the protected signals is a really good thing. Again, that means 4 layer boards.

a) 4 layer boards are much easier to get right
b) you really need an unbroken ground plane for return currents. This is often incompatible with having just two layers.
c) putting the ground plane much closer to the protected signals is a really good thing. Again, that means 4 layer boards.
