Example impedance-controlled traces for 2- and 4-layer PCBs ... When he noise-tested the PCB, emissions from the four-layer version were greatly reduced compared to the original design.

Explore the intricate process of multilayer PCB manufacturing, where precision and technology come together to create ...

In the case of a 2-layer board these just go right through ... But we think the concepts can easily be translated to other PCB layout software like Kicad.
