Description

V. Description of the invention (1). The present invention relates to a three-element synthetic electroplating method. The plating solution is synthesized by using copper, tin, and zinc metal, so that the plating layer in the electroplating process is uniform in color and wear resistance. Structure with high degree of surface smoothness. BACKGROUND OF THE INVENTION In the recording industry, due to the different needs of the finished products, several elements are placed in the electroplating process to combine with each other in order to achieve a coating with good abrasion resistance and good surface smoothness. It is a combination of nickel, tin, and metal. The nickel metal can achieve good wear resistance, oxygen resistance and corrosion resistance; however, because nickel metal can produce carcinogens after plating, nickel The use of metal and the additives required in the conventional electroplating process are cyanide-containing substances, so it is less suitable for arbitrary transportation in the work process, which causes the inconvenience in the workflow and the lack of quality of the finished product. · And when the nickel metal is electroplated on the terminal surface, the nickel metal has poor solderability, high electrical resistance and poor conductivity, and has a small amount of magnetism, which may cause interference during communication. When the nickel metal is replaced with gold or silver metal, it can reduce the various defects generated by the nickel metal, but the gold 'silver metal has poor oxygen resistance, poor wear resistance, poor corrosion resistance and cost. It is so high that it is inconsistent with economic benefits. In view of this, the inventor is based on years of experience in the industry and research and development. After a long period of research and development, he developed the plating method in this case, and hopes to improve the field of plating methods that cannot be broken in the medium and long term. And electroplating a key layer structure that meets the needs of the industry. Object of the invention

V. Description of the invention (2) The electric ore method of the present invention is a plating layer with good money after obtaining the electric boat. The invention of the inventive ore method is based on controlling and conducting the electric layer to be uniform in color and low in conductivity. The main purpose of using the effect is to make the effect of this hair easier. The main purpose is to explain the process of the pre-treatment ore in the main process by using the plating solution layering as a colored feature to confirm the characteristics. The uniform, smooth, and non-magnetic plating method. Mingzhi's use technology is understood to be: to provide a combination of three elements of copper, tin, zinc metal combination, make Zejia, and high wear hardness and smooth surface to meet the actual needs of users. The symptom is: a plating solution after the bath-building process in the electroplating process of the three elementary synthesis makes the structure of the invention good after plating, high abrasion resistance, good weldability, and electrical interference after the complete process. For a good paragraph, creative purpose, characteristics and techniques, and hand-to-hand drawings, explain them one by one: Brief description of the drawings_ The first diagram is a schematic flow chart of the plating method of the present invention. The preferred embodiment of the invention First, please refer to the first figure, which is not intended for the three-element synthesis electroplating method of the present invention. The electroplating process includes a pretreatment A, a plating process B, and a cleaning process C. , Drying process]) and-finished product; of which: pre-treatment A: the object to be electroplated is subjected to the acid washing process, and then washed and washed after the water washing process and dried to make it a dry state of the electric shovel.
