Basic knowledge of connector terminal plating

Terminal plating is a metal electrodeposition process, refers to simple metal ions or complex ions through electrochemical methods in the solid (conductor or semiconductor) surface discharge reduction for metal atoms attached to the electrode surface, so as to obtain a metal layer of the process. Plated terminals not only resist corrosion and have better electrical properties, but also have durability and solderability to withstand high temperatures. When the metal is used, the connecting area is selectively plated with precious metals to reduce costs, and other parts of the terminal can be plated with tin or nickel. Tin is especially used for the soldering end area of a terminal. 1. Definition Electroplating: is a kind of metal electrostatic buildup process, refers to the process of obtaining a metal layer by electrochemical discharge of simple metal ions or complex ions on the surface of solids (conductors or semiconductors) to restore metal atoms to the surface of the electrodes, thus obtaining a metal layer. 2. Purpose Electroplating is used to modify the appearance of solids by changing their external properties and thus altering the appearance and improving corrosion resistance, wear resistance and hardness, and providing special hardness. Strengthen the hardness, to provide special light, electricity, magnetism, heat and other exterior properties. 3. Terminal plating introduction to the majority of electronic connectors, terminals have to make the appearance of the treatment, commonly referred to as electroplating. There are two main reasons: one is to maintain the terminal reed substrate from corrosion; the second is to optimize the performance of the terminal appearance, set up and adhere to the contact interface between the terminals, in particular, the membrane layer control. In other words, to make it easier to complete the metal-to-metal contact. Contact is the articulator to complete the electric connection function of the central parts. Ordinary by the positive contact and negative contact components composed of contact pairs, through the insertion of the yin and yang contact components to complete the electrical connection.-4、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | wiring harness | wire and cable product solutions that we can provide, please contact our Division below!
