In the production process of using electroless nickel plating solution, sometimes the welding performance of the coating is poor. What is the reason?
When we use the zinc plating color passivator, the passivation film of the workpiece will appear black spots. Is this due to the influence of metal impurities?
In the production process of bright copper electroplating, we can quickly obtain good brightness, filling and displacement ability by adding acid copper plating brightener normally.Sometimes we find that the consumption of brightener is much higher than usual. What is the reason?
Using acid copper plating brightener, mirror bright coating can be obtained on the surface of the workpiece, and the coating has good filling and corrosion resistance.Sometimes the filling and leveling performance of the products produced is poor. What is the reason?
In the production process of using alkaline zinc nickel alloy additive, the workpiece will be blackened at the hook, which will seriously affect the appearance quality of the workpiece.So, what causes this phenomenon?
In recent years, the tin plating process has been rapidly promoted in the electronic industry, and the requirements for the weldability of workpieces are becoming higher and higher.Some workpieces have poor welding performance of tin coating after using tin plating additives, which will greatly increase the failure rate due to welding quality problems.So what factors will affect the welding performance of the coating?
