Abstract:
The stability of an electroless plating bath for depositing a metal (e.g., nickel) is determined by titrating a sample of the plating bath with a titrant comprising ions of a catalytic metal (e.g., palladium) and detecting hydrogen released at the titration endpoint. The quantity of titrant required to attain the endpoint provides a measure of the stability of the electroless plating bath.
