Electrical Components Connector on the gold-plated: called the golden Finger, refers to by a lot of golden conductive contacts, because its surface gilded and conductive contacts arranged like fingers, so called "golden finger." The golden finger is actually on the copper cladding through a special process and then coated with a layer of gold, because gold is extremely antioxidant, and the conductivity is also very strong. Only part of the high-function server/Workstation accessory touch Point will continue to use gold-plated practice, the price is naturally expensive. Gold-plated layer appearance is golden, with high chemical stability, gold-plated layer ductility, easy polishing, high temperature resistance, with a good anti-discoloration function. Gold plating has a low touch resistance, good conductive function, easy to weld, strong corrosion resistance, and has a certain wear resistance (refers to hard gold), so in fine instrumentation, printed circuit boards, integrated circuits, tubes, electrical contacts and other aspects have a wide range of use.
