Terminal wire harness is mainly composed of wires, terminals and a plastic body. The material of the terminal is generally copper, and copper is a very active metal. It will react with oxygen in the air when exposed to the air, and the surface will oxidize, so the terminal harness Surface electroplating must be done, and the more commonly used surface is gold plating.
Some companies do not make gold plating due to cost considerations when purchasing terminal wiring harnesses, and it is prone to serious problems of plating wear after use of terminal wiring harnesses, leading to poor contact. The temptation of low prices may not be a cost reduction, but may be a trap that exposes your business to huge risks! The following are some common problems and suggestions:
1. If the plating layer is 1u", the gold plating layer is too thin; the gold layer is easy to wear;
2. The gold layer will wear out due to the influence of the environment;
3. Defects in product structure can easily accumulate dust;
1. It is recommended that the plating layer of the customer is generally 3--5u" to increase the wear resistance of the gold plating layer.
