Abstract

A specific relationship for characterizing a palladium/tin (Pd/Sn) catalyst, which is used in an electroless copper plating bath, is the comparison between Cyclic Voltammetry of a dilute catalyst bath and the palladium concentration of the same bath. An equation derived from the results provides a vehicle to predict the plating performance of a bath. The procedure for the characterization is as follows.
