Abstract
The performance of anode is of considerable importance in determining the success of an electroplating process. Usually anodes used for electroplating are of two types namely (i) soluble and (ii) insoluble. Mostly soluble anodes are used in almost all the plating electrolytes in view of maintaining the concentration of cations as required. However under certain critical conditions, it becomes a must to use insoluble anodes. Such characteristically significant anodes, behave differently in the baths when their position, size, shapes etc are changed. This aspect is not elaborately investigated and reported in the literature. Investigations were carried out in the conventional cyanide and acid copper baths using soluble as well as insoluble anodes of different shapes and sizes and the results are reported in this paper
