接线端子做电镀处理，一方面是为了保护端子簧片基材不受腐蚀；另一方面则是为了优化端子表面的性能，建立和保持端子间的接触界面。那么接线端子要怎么做电镀处理呢？

　　Electroplating terminal, on the one hand, is to protect the terminal reed substrate from corrosion; On the other hand, to optimize the performance of the terminal surface, establish and maintain the contact interface between terminals. So how do wiring terminals do electroplating?

　　端子表面性能的优化可以通过两种方式实现，一是在于接线端子的设计，建立和保持一个稳定的端子接触界面；二是建立金属性的接触，要求在插入时，任何表面膜层是不存在的或会破裂。

　　The optimization of terminal surface performance can be realized in two ways: one is the design of terminal, to establish and maintain a stable terminal contact interface; The second is to establish a metallic contact, which requires that at the time of insertion, any surface film layer is not present or will break.

　　没有膜层和膜层破裂这两种形式的区别也是贵金属电镀和非贵金属电镀的区别。贵金属电镀，如金、钯、及其合金，是惰性的，本身没有膜层。因此，对于这些表面处理，金属性的接触是“自动的”。

　　The difference between the two forms of no film layer and broken film layer is also the difference between precious metal plating and non-precious metal plating. Precious metal plating, such as gold, palladium, and their alloys, is inert and has no film of its own. Therefore, for these surface treatments, the contact of metallic properties is “automatic”.

　　为了确保菲尼克斯端子表面的性能不受外来因素，如污染、基材扩散、端子腐蚀等的影响。非金属电镀，特别是锡和铅及其合金，覆盖了一层氧化膜，但在插入时，氧化膜很容易破裂，而建立了金属性的接触区域。

　　In order to ensure that phoenix terminal surface performance is not affected by external factors, such as contamination, substrate diffusion, terminal corrosion, etc. Non-metallic electroplating, particularly tin and lead and their alloys, covers an oxide film that is liable to rupture when inserted, creating a metallic contact area.

　　另外，对于附着性较差的金属，电镀前通常要打铜底用以增强附着性；原素材如铁，磷铜的导电率通常都在20％以下，对于低阻抗要求的连接器无法满足要求，故在表层电镀金等高导电率金属后可降低其阻抗。

　　In addition, for the poor adhesion of the metal, usually before electroplating copper bottom to enhance the adhesion; The conductivity of the original materials such as iron, phosphorus and copper is usually below 20%. The connector with low impedance requirements cannot meet the requirements. Therefore, the impedance can be reduced after the surface electroplating and other high conductivity metals.
