<p>Reference voltages selectively calibrated in a circuit 110 to match electrolyte being processed, influence adjustment of current controller 114 and driver 106 through which plating voltages are applied to primary and secondary electrodes 26, 28, 30, 32 of a dual chamber tank assembly. The primary reference voltage is modified by feedback 122 of sensed secondary plating current from the secondary cathode (32). The reference voltages are regulated and limited to enable transfer of information between cascaded tank assemblies. <IMAGE></p> |
