NICKEL ELECTROPLATING COMPOSITIONS WITH COPOLYMERS OF ARGININE AND BISEPOXIDES AND METHODS OF ELECTROPLATING NICKEL

摘要

To provide compositions enabling the electroplating of nickel deposits which have uniform bright surfaces over wide current density ranges even on irregular shaped articles such as electrical connectors and leadframes.SOLUTION: Nickel electroplating composition includes one or more sources of nickel ions, one or more compounds chosen from sodium saccharinate, boric acid and salts of boric acid, optionally, one or more sources of acetate ions, and one or more copolymers of arginine and one or more bisepoxides.SELECTED DRAWING: None
