Electroless plating requires the catalytic treatment of the surface to be plated to ensure thorough plating. A measurement of the catalytic activity is vital to ensure that the plating will be of an acceptable quality. The following method provides a direct quantitative measure of catalytic activity. (Image Omitted) The method measures the absolute catalytic toward a reducing agent of a particular system (formaldehyde in the case of electroless copper). The described method involves the substitution of an alternative reduction reaction for the metal ion reduction. The net result of this substitution is that the palladium is not masked by plated metal.
