Abstract

PURPOSE: To obtain a thick and uniform plating of a noble metal by using a plating liquid for Au, Pd, Ag, etc., to which is added potassium acid pyrophosphate.
CONSTITUTION: A plating liquid of a noble metal is prepared from a salt of Au, Pd, Ag, etc., a potassium acid pyrophosphate (e.g., dipotassium dihydrogen pyrophosphate), and a thiocyanate. The addition of the thiocyanate is made with the intention of continuously and safely using potassium acid pyrophosphate, although they form a complex with a metal. Actually, a noble metal salt is added little by little to a potassium acid pyrophosphate-potassium thiocyanate solution while stirring. Using the plating liquid, electrolytic plating is performed.
