ABSTRACT:
A copper replenishment system for replenishing copper which is depleted from a copper plating solution. The replenishment is achieved by the use of a compact filter cartridge, which is inserted into a recirculating loop for the solution. The filter cartridge contains a chemical, which when reacting with the solution replenishes the copper into the solution. The filter cartridge is a compact unit which can be easily handled and reduces the amount of contaminants that could be introduced by the presence of the replenishment chemical.
