In the production process of using acid copper plating brightener, the dispersion ability of workpiece coating is relatively poor, and the thickness difference between high and low areas is relatively large. What causes this?
In the production process of using electroless nickel plating solution, the addition of solution should be standardized.If the adding method is not accurate, which is likely to lead to instability of the plating solution, what should be paid attention to when adding the solution?
In the process of using nickel plating additive, the workpiece coating is prone to the phenomenon of concave points, which has a great impact on the appearance of the workpiece.What causes this phenomenon?
In the production process of using electroless nickel plating solution, the workpiece needs to go through a heat treatment process. What's the role of this?
In the production process of the potassium chloride zinc plating brightener we used, after the plating solution is heavily treated, the workpiece coating is prone to appear black and gray, and the Hull cell test coupon is also gray,and after adding brightener, the coating will be bright. What is the reason?
In the process of using chromium plating additives, sometimes the content of trivalent chromium in the plating solution will increase, resulting in the workpiece coating rough, dark, poor brightness and other problems.So how do we reduce the content of trivalent chromium in the bath?
