Printed Circuit Board Processing Of Copper Etching

Etching Process Of Printed Circuit Board PCB

Currently, the typical process for printed circuit board (PCB) processing uses "graphic plating". That is, firstly, a layer of lead-tin resist is pre-plated on the portion of the copper foil to be retained on the outer layer of the board, that is, the pattern portion of the circuit, and then the remaining copper foil is chemically etched away, which is called etching.

Printed Circuit Board Fabrication - Etching Outer Layer

The typical PCB (Printed Circuit Board) manufacturing operation today is building PCBs using a process described as pattern (electro)plating. In this process the outerlayer panel arrives at the etching operation with an “etch resist” of Tin or Tin/Lead protecting certain areas of the Copper foil, this defines the circuit pattern that will remain after etching.
