Plating layer issues
Thread Content
Burring and coarse grains in the electroplated layer are usually caused by those reasons; how to solve them?
Burring and coarse grains on the coating are mainly caused by contamination of the plating solution with suspended impurities. Its sources are: dust in the air, sludge from the anode, and the hydrolysis products of metal impurities. In addition, there are issues such as abnormal plating solution composition and substandard operating conditions. The solution is to adjust the composition of the plating solution and the operating conditions. If it is caused by suspended impurities, the plating solution should be filtered
