A terminal includes a contact portion and a soldering portion for being soldered to a circuit board. A metal coating is plated on the contact portion and is made of a chromium-carbon material, so that the contact portion has desirable electric conductivity and strong hardness, and has desirable corrosion resistance. Hence, a manufacturing process of the terminal uses a common chromium-carbon material to form the metal coating to replace a gold conductive layer, thereby reducing the manufacturing cost of the terminal. Further, it is unnecessary to use toxic substances during plating, which greatly reduces environmental pollution, and effectively protects the environment. |
