Pin header row mother plating knowledge Introduction Most electronic connectors, terminals have to be surface treatment, generally refers to electroplating. There are two main reasons: First, the protection of the terminal reed substrate from corrosion; the second is to optimize the performance of the terminal surface, to establish and maintain the contact interface between the terminals, especially the film control. In other words, it makes it easier to achieve metal-to-metal contact. Electronic wiring harness

    1, to prevent corrosion: Most connector reeds are made of copper alloy, usually corrosion in the use of the environment, such as oxidation, curing and so on. Terminal plating is to reed and the environment isolation, to prevent the occurrence of corrosion. Electroplating materials, of course, will not corrode, at least in the application environment.

    2, surface optimization: Optimization of the terminal surface performance can be achieved in two ways. First, the design of the connector, the establishment and maintenance of a stable terminal contact interface. The second is to establish a metallic contact, requiring insertion of any surface film is not present or will rupture. No difference between the two forms of film and film rupture is the difference between precious metal plating and non-precious metal plating.
