Re: [EE] PCB design

I agree that since SMT components already have pads on the top of the
board, it makes sense to do most of the routing there. I've been using
KiCAD for four layer boards. Signals on top and bottom (most on top),
ground on layer 2, and Vcc on layer 3.

A recent 4 layer board is pictured at
