Abstract

1360592 Electroless Co-plating baths RCA CORPORATION 14 Feb 1973 55533/73 Divided out of 1345868 Heading C7F An aqueous Co-plating bath comprises a Cosalt, a linear polyphosphate, ammonium hydroxide or an amine, and a substituted amine borane, e.g. monoethyl, monomethyl, diethyl-, dimethyl- or tertiary butyl-amine borane. The bath may also contain Ni, Fe, MoO 4 and WO 4 ions. Cu or Ni may be electro-plated on the Co. The substrate may be Cr, Al, Mo, Ag, Cu, Au or Pd-activated insulating substrates.
