How to Make a Printed Circuit Board (PCB) | PCB | .

Deze pagina vertalen

A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring, ... The FeCl3 reacts with the unmasked copper and removes the unwanted copper from the PCB. This process is called Etching. Use pliers to take out the PCB and check if the entire unmasked area has been etched or not.
