摘要

Electroplating apparatus for circuit boards (12) has a conveyor (18) whose rollers have a conductive coating, allowing it to act as cathode. The anode (20) consists of sheet metal and is mounted on adjusting screws (22). This allows its shape to be changed to provide the desired current density between it and the boards at different points. An independent claim is included for a method for operating an electroplating apparatus comprising altering the shape of the anode to provide different thicknesses of coating at different positions.
