Technical Field

[0001] The utility model relates to the technical field of electronic component electroplating, in particular to a stirring device for surface treatment liquid of a mobile phone mid-plate. Background Art

[0002] Surface treatment liquid in the electroplating field generally refers to electroplating liquid, which is an indispensable part of the electroplating process. According to the different metal ions contained, it can be divided into various types such as copper, nickel, chromium, zinc, etc. These surface treatment liquids are deposited on the surface of the substrate to be plated through electrolysis to form a layer of metal (or non-metallic) coating in order to achieve the purpose of protection, decoration or improving material performance.

[0003] The surface treatment liquid needs to be stirred with a stirring device before use. The stirring action makes the components in the surface treatment liquid evenly distributed, thereby improving the electroplating efficiency and coating quality. Since the surface treatment liquid has a certain viscosity, the free energy of the ions is low. The general stirring device does not have a heating function or only has a heat source set outside the stirring device. The surface treatment liquid is not heated uniformly and the stirring effect is poor. Utility Model Content
