How to improve the performance of the row of pins and row of female connectors

1. i.e., the control of existing and impending thin films located on the surface of the contact plating. One of the major requirements for the electrical performance of a pin and busbar is the establishment and maintenance of a stable pin and busbar impedance. To accomplish this, a metallic contact interface is required to provide this 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 precious metal to prevent the influence of external factors such as contaminants, the diffusion of the substrate metal, as well as the contact wear and tear. 3. ordinary metal plating, especially tin or tin alloy, the performance of which are naturally covered by a layer of oxidized thin film. Tin contact plating works because this oxide layer is easily destroyed during mating so that metal contact is easily 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 Z main performance degradation mechanism for tin contact coatings. The silver contact plating of the needle and busbar Z is preferred to be treated as an ordinary metal plating, because the plating is susceptible to corrosion by sulfides and hydrides. Nickel plating is also usually treated as a common metal due to the formation of valve warps.-3、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
