Example impedance-controlled traces for 2- and 4-layer ... re-working the board may be next to impossible: another reason to stick power planes in there. Routing a four-layer PCB can involve ...
In the case of a 2-layer board these just go right through and connect ... But we think the concepts can easily be translated to other PCB layout software like Kicad.
