PURPOSE: A discrete feed system for a vertical continuous plating machine is provided to improve the plating quality on a printed circuit board by supplying electricity to the printed circuit board dipped in plating liquid of a plating bath through separate electrode plates. CONSTITUTION: A discrete feed system for a vertical continuous plating machine comprises rectifiers(5), cables(6), electrode plates(7), and a plating bath(4). The rectifiers transfer specified current to the electrode plates so that electroplating takes place when a hanger holding a printed circuit board(1) continuously moves to pass through the electrode plate section. When the printed circuit board reaches the next electrode plate after passing through an electrode plate, the current supply to the former electrode plate is cut off.
