When we use electroless nickel plating solution, in theory, the workpiece as long as immersed in the plating solution at any position can obtain uniform coating.In the production process, the workpiece in the hole, slot, slot and other positions can not get good coating, mostly to deep hole, blind hole or through hole.
In the production process of using nickel plating additives, sometimes the workpiece coating appears rough and burrs.Even if the plating solution is treated with impurities, this will happen again soon, which is very troublesome.What causes this phenomenon?
When we use alkaline zinc nickel alloy plating additive for production, sometimes the coating in the high current area of the workpiece has stripes, which will seriously affect the appearance and performance of the coating. So, how can this phenomenon occur?
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?
