Description

Technical Field

[0001] The present application relates to the field of electroplating processing, and in particular, to an electroplating tank with uniform coating. Background Art

[0002] Electroplating technology is a traditional technology, which is widely used in surface decoration, surface modification (increasing hardness, magnetism, etc.), surface protection, etc. In terms of industry, it is applied in many industries, such as automobiles, mobile phone decoration, functional plastics, PCB, semiconductors, etc.

[0003] At present, people have found that an important factor affecting the surface quality of electroplating is the plating tank used for electroplating. However, the electroplating processing equipment currently used adopts bottom-type electroplating during use, but it cannot guarantee that each surface of the product to be plated meets the required smoothness requirements, and many electroplating processes are implemented by manpower, with low work efficiency and long waiting time.
