SUB connector plating is divided into several categories, what is the role?
SUB Connector plating is divided into several categories, what is the role? General SUB connector plating is divided into: gold plating, silver plating and tin plating; according to the application requirements of the different thickness of the plating is not the same; and the main role of the connector plating is: ① good conductivity; ② reduce impedance; ③ improve the strength of wear; ④ anti-corrosion.
Ordinary metal plating surface covered with a layer of oxide film, to ensure that the oxide film in the waterproof usb socket with breakage, to ensure that the contact interface is no longer oxidized.
A, precious metal plating to produce interface metal contact is relatively simple, and maintain the stability of the contact interface impedance. Optimize electrical performance, build and maintain a stable socket impedance.
To a certain extent, improve the mechanical properties of the socket and enhance its wear resistance.
