TLDR
In this article, the electroless nickel-plating liquid adopts a compound of a bismuth salt as a stabilizer, which easily dissolves in a high concentration of an electroless Nickel plating stock solution, and imparts excellent electrically resistive properties to a film 2 plated in the plating liquid.Abstract:
PROBLEM TO BE SOLVED: To provide an electroless nickel-plating liquid containing no lead, and to provide a plating method using the same. SOLUTION: The electroless nickel-plating liquid adopts a compound of a bismuth salt as a stabilizer, for example, bismuth ammonium citrate, bismuth potassium tartrate and bismuth sodium tartrate. Which easily dissolves in a high concentration of an electroless nickel-plating stock solution. Thus, the prepared electroless nickel-plating liquid has the bath life favorably compared with a conventional electroless nickel-plating liquid containing lead as the stabilizer, and imparts excellent electrically-resistive properties to a film 2 plated in the plating liquid.
