Why Do We Use Copper to Make PCB Traces?
A printed circuit board (PCB) is made up of several layers, including the substrate, traces, soldermask, and silkscreen. The traces are a crucial element, because they carry the electrical signals to different components across the board. Without the traces, the PCB wouldn’t function.
