[0002] The electroplating process is to immerse the workpiece in a metal salt solution and connect it to the cathode of a DC power supply. The anode is made of soluble or insoluble materials, and a layer of bright metal or alloy is deposited on the metal surface by electrolysis. Rack plating is a common method in the electroplating industry. It is to use a hook-like object on the production line to hang the workpiece and electroplate it in the electroplating tank. Rack plating is suitable for products of general size and a coating thickness of more than 10μm. There are many parts in life that need rack plating, such as electroplating heat spreaders.
