Abstract

1,243,134. Electroless nickel plating. TEXAS INSTRUMENTS Inc. June 17, 1969 [July 29, 1968], No. 30592/69. Heading C7F. An electroless nickel-hyposphosphite plating bath contains glutamic acid or a glutamate. The bath may comprise Ni ions 0À079 to 0À189 moles/l., hypophosphite ions 0À132 to 0À297 moles/1., glutamate ions at least twice that of the Ni ions, succinate ions at least twice that of the Ni ions and ammonium thiocyanate 0À3 to 0À6 p.p. m., temperature 170‹ F. to boiling and pH 4À0 to 9À0. The glutamate may be monoammonium, monosodium, monopotassium and calcium glutamates. Thiourea may be added as a stabilizer. The substrate may be Cu, Fe, Co, Ni, Pd, Pt, Ag, Au, Al, B or plastics activated with Pd. The constituents of the bath may be prepared as a dry mix which may be pelleted or packaged in water-soluble plastics bags.
