Balancing Anodes


Balancing anodes

When operating anodes in electrodeposition of metals such as copper, tin, nickel and zinc there is a tendency to generate an excess of metal ion species in the plating solution.  As the concentration of metal ions increase, plating quality can diminish. To minimize this, platers would typically either dummy plate or decant their plating baths in order to maintain an optimal metal ion concentration. In either case, additional costs are incurred due to lost production or supplementary waste treatment.  A third very cost -effective method for controlling metal ion growth is to replace a portion of the soluble anodes with De Nora DSA® anodes. Operating these anodes will maintain “balance” in the bath and extend electrolytic life.
