How to create a PCB? 1. Design the PCB. This involves creating a schematic of the circuit and a PCB layout. The schematic shows the components of the circuit and how they are connected. The PCB layout shows the copper traces, pads, and holes on the PCB. 2. Fabricate the PCB. Etch the copper traces onto the PCB substrate. The PCB substrate is a material that is used to support the copper traces. The etching process removes the copper from the areas that are not covered by the solder mask. 3. Asse
