In the production process of using acid matte tin additives, sometimes the coverage of the tin plating layer is poor, which affects the quality of the plating layer. What is the reason?
In the production process of using acid tin plating brightener, sometimes pinholes appear on the surface of the tin plating layer of the workpiece. What is the reason?
In the production process of using sulfate electroplating tin additives, sometimes there will be white fog on the tin plating layer. What is the reason?
In the production process of using sulfate tin plating additives, sometimes the corners of the workpiece appear scorched. What is the reason?
In the production process of using acid tin plating brightener, since the workpiece is easy to bring Fe2+ into the plating solution during the pickling process, the Fe2+ solution produced by the corrosion of the steel equipment is easily brought into the plating solution.So what effect does Fe2+ have on the performance of the tin plating layer?
Metal salts and reducing agents coexist in the high-phosphorus electroless nickel plating solution and are in a metastable state.Proper maintenance of the bath during use can improve the service life of the bath and the quality of the coating.So how should the plating solution be maintained?
