Description

technical field [0001] The invention relates to the technical field of electroless nickel plating, in particular to an electroless nickel plating solution processing device and a processing method thereof. Background technique [0002] The electroplating industry is an indispensable and important process in my country's manufacturing industry, and the electroless nickel plating process is an important branch of the electroplating industry, which has been widely used in the automobile industry, electronics industry and other industries. The fastest growing type of electroless plating, the plating solution generally uses nickel sulfate, nickel acetate, etc. as the main salt, hypophosphite, sodium borohydride, borane, hydrazine, etc. as the reducing agent, and various additives are added. Work in an acidic solution at 40-50°C or in a neutral or alkaline solution close to room temperature. According to the different reducing agents used, it can be divided into two categories: e...
