I. How to improve the electrical performance of the connector through plating? The life of the row of pin female connector is directly linked to its electrical performance, and row of pin female connector performance performance want to get higher optimization, but also can only rely on the plating, so that the quality of plating directly determines the connector electrical performance how, 1, that is, the control of the already existing and will soon be formed is located in contact with the surface of the plating film. One of the main needs of the electrical performance of the row of pins and bushes is to establish and maintain a stable impedance of the row of pins and bushes. To accomplish this, a metallic contact interface is required to provide such inherent stability. Establishing such a contact interface requires a surface film that can be avoided or split during the contact fit. These two different choices clarify the distinction between precious or rare metals and common metals.2. To varying degrees, precious metal coatings (e.g., gold, palladium, and their alloys) are intrinsically free to the surface film. For these coatings it is relatively simple to produce interfacial metal contact, since it requires only the movement of the concomitants of the contacting surfaces during mating. This is usually easily achieved. In order to maintain the stability of the impedance of the contact interface, row of pins and row of mother design requirements should pay attention to maintain the contact surface of precious metal to prevent external factors such as contaminants, the diffusion of the base metal as well as contact wear and tear of the impact. 3, ordinary metal plating, especially tin or tin alloy, the performance of which are naturally covered by a layer of oxidized film. The role of tin contact plating, because this layer of oxide is easy to be destroyed at the time of mating, so that the metal contact is easy to be established. The need for a pin and busbar design is to ensure that the oxide film breaks down when the pin and busbar are mated, while ensuring that the contact interface is no longer oxidized during the lifetime of the electro-connecting adherent. Re-oxidizing corrosion, in the case of abrasion corrosion, is the dominant performance degradation mechanism for tin contact coatings. Pin row mother silver contact plating is better treated as a common metal plating, because the coating is vulnerable to corrosion by sulfides and chlorides. Nickel plating is also usually treated as a common metal due to the formation of valve warps.
