JXD6-0002NL Single Port Tap Up Surface Mount 100 Base-T RJ45 Connector

RJ network interface PIN needle touch resistance and 4 major elements of reliability:
3, appearance shape
The surface shape includes the planned shape and the environmental state. The surface of the touch part may be a loose surface film formed by mechanical adhesion and accumulation of dust, rosin, and oil on the surface of the contact. This surface film is easy to be embedded because of the particulate matter. Hidden in the microscopic pits on the touch surface, the touch area is reduced, the touch resistance increases, and it is extremely unstable. The second reason is that the pollution film formed by physical adsorption and chemical adsorption is mainly chemical adsorption to the metal surface, which occurs along with the migration of electrons after physical adsorption. Therefore, for some products with high reliability requirements, such as electrical connectors for aerospace, it is necessary to have clean assembly and production environmental conditions, complete cleaning processes and necessary structural sealing measures, and the application unit must have outstanding storage and operation operations. Environmental conditions.
