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.
