Inventor: KAWAKAMI HIROSHI
IPC: C23C18/36
Filed: 2000-01-12
Abstract: PROBLEM TO BE SOLVED: To separate phosphite produced and accumulated in an electroless nickel plating solution exhaused in by plating operation as calcium phosphite therefrom and to reuse the same as a plating solution. SOLUTION: For regenerating a plating solution having a fundamental composition obtained by combining nickel hydroxide, nickel carbonate or nickel hypophosphite to form into a nickel source and hypophosphorous acid, nickel hypophosphite or sodium hypophosphite to form into a reducing agent, a calcium carbonate or calcium hydroxide is added to the plating solution. In this way, phosphite produced and accumulated in the plating solution by the oxidation of hypophosphite is precipitated and formed as calcium phosphite. At this time, the amount of calcium carbonate or calcium hydroxide to be added is controlled so that the pH of the solution upon the end of the reaction reaches 4.5 to 5.8, and moreover, hypophosphorous acid is added.
