Copper foil over-etching in PCB fabrication can be caused by changes in specifications without adjusting etching parameters, poor drying after etching, local collisions during the PCB process, and unreasonable circuit design. This can result in excessive corrosion, separation of the zinc layer, and copper wire fall-off.
