Abstract
A method and apparatus for electroplating a workpiece to achieve a uniform plating thickness includes a cathode rack having a hook from which the workpiece is suspended and spaced apart from a consumable anode. The rack includes a plurality of plates made of the same material as the anode disposed on opposite sides of the rack. The plates direct a portion of the current emanating from the anode away from the workpiece to produce more uniform plating.
