ABSTRACT:
There is disclosed electroplating apparatus in which a plurality of anodes and a twice-as-large plurality of first and second cathodes are disposed in a cell such that each anode has on its opposite sides a first cathode and a second cathode, respectively. First and second adjustable constant current sources supply current to, respectively, all first cathodes and such anodes and all second cathodes and such anodes. A plurality of current adjusting units respective corresponding to the anodes are connected on the anodic side of each such current source between that source and each respective anode. The anodes are permanently installed in the cell, while the cathodes are carried by a holder fitting over the top of the cell and removable therefrom. The cathodes may be selectively inserted into guideways in their holder and then locked in place in these guideways until removal of the cathodes is desired, when they are unlocked.
