ABSTRACT:
A palladium electroplating process is described in which a unique compound is used to supply palladium to the electroplating bath. The procedure is particularly useful where a polyamine such as 1,3-diaminopropane is used as the complexing agent for palladium in a palladium electroplating bath. The unique compound is palladium-1,3-diaminopropanedichloride which is highly stable, can be made in pure form, and is readily soluble in water, aqueous solutions, and typical palladium baths.
