摘要： An electroless nickel plating solution and a method of using the same to produce a nickel deposit having a phosphorus content that remains at about 12% throughout the lifetime of the electroless nickel plating solution is disclosed. The electroless nickel plating solution comprises (a) a source of nickel ions; (b) a reducing agent comprising a hypophosphite; and (c) a chelation system comprising: (i) one or more dicarboxylic acids; and (ii) one or more alpha hydroxy carboxylic acids. The electroless nickel plating solution may also comprise stabilizers and brighteners.
