Introduction to the PCB Etching Process, PCB Etching types, PCB Etching working, PCB Etching processes
Hello everyone, I hope you all are doing well. In today’s tutorial, we are going to discuss the PCB Etching process, a fundamental step in PCB manufacturing. The PCB Etching process is used to remove the unwanted copper from the PCB surface to reveal the desired circuit pattern. As we know, a PCB board has a complete copper layer in its raw form. We design our circuit in the software(i.e. Eagle, Altium, Proteus etc.) and place the pattern on the PCB board. This circuit pattern is normally protected by the tin plating, as shown in the below figure:Now, there’s a need to remove the extra/unwant ...
