How are the patch connectors in wire-to-board connectors?

Connector types are complex, according to the shape can be divided into: circular connectors, rectangular connectors, square connectors, customized connectors and so on. According to the contact body termination: crimping, welding, winding; screw (cap) fixed; according to the articulation can be divided into: board-to-board connectors, wire-to-board connectors, wire-to-wire connectors.

-I. Wire to board connectors in the chip connector is how? Chip connector is divided into: lying paste connector (SMT) and vertical paste connector (DIP). SMT is generally mounted pinless or short-lead appearance of the assembled Yuan equipment, the need for the first printed solder paste on the circuit board, and then mounted through the chip machine, and then through the reflow soldering fixed equipment. The DIP welding is inline package equipment, through the wave soldering or manual welding fixed equipment. Chip connector over the furnace temperature of 260 ° above 3-5 s. Chip connector composition: plastic parts and pin pin, plastic parts of the raw materials are generally PA6T and PA9T, are high temperature raw materials. SMD connectors are generally used in highway cameras, stereo DC fans, intelligent electronics, air conditioning, high-definition LCD televisions, notebook computers and other fields. The raw materials of Pin are generally brass, bronze, phosphor bronze and so on. Plating is generally gold-plated (half-gold) or tin-plated, etc. The role of Pin plating is to resist oxidation, improve the conductive function, and improve the transmission speed of the signal.
