Abstract
Improved compositions and method for electrodepositing palladium and palladium alloys utilizing palladium amine compounds are described. The improvement comprises maintaining the electroplating bath at a pH ranging from about 6.5 to 9.5 during operations with a borate buffer resulting from the neutralization of boric acid with ammonia, ammonium hydroxide, and alkali metal hydroxide or an amine.
