In the production process of using acid copper plating brightener, sometimes the concentration of various components in the plating solution is normal, and the workpiece with small area is uniformly bright, while the surface of the workpiece with large area is easily foggy. What is the reason?
In our production process, when the electroless nickel plating additive is added to the plating solution, but the workpiece is not plated, what is the reason?
In the production process of using acid copper plating brightener, the high current area of the workpiece is prone to scorch, which will seriously affect the quality of the workpiece coating.What causes this phenomenon?
In the process of using acid copper brightener, the appropriate amount of chloride ion in the plating solution can reduce the stress of the copper coating, improve the toughness of the copper coating, and also improve the brightness and flatness of the copper coating.However, when the chloride ion content is too high, it will lead to rough coating, dendritic stripes and loss of brightness.So how do we remove the excess chloride ion in the plating solution?
