Description

Technical Field

[0001] The present invention relates to the technical field of electroplating treatment, and in particular to an electroplating conduction jig and a preparation method thereof. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on the metal surface. It is a necessary process in wafer processing and PCB board processing. The jig used in the electroplating process needs to have clamping and conductive functions. The existing electroplating jig uses a metal frame structure to achieve the conductive function, and uses screws on the metal frame structure to fix the spring and wrap the spring with silicone to achieve the clamping function. However, since the metal main structure needs to be immersed in the electroplating solution for a long time, it will be corroded by the electroplating solution and has a short lifespan.
