  There are many types of connectors, which can be divided into circular connectors, rectangular connectors, square connectors, customized connectors, etc. according to their shapes. According to the contact body termination method: crimping, welding, winding; screw (cap) fixing; according to the connection method can be divided into: board-to-board connector (B to B), wire-to-board connector (W to B), Wire to wire connector (W to W). Let's talk about the patch connector in the wire-to-board connector today.

  Surface solder placement technology has been used by some manufacturers since the 1950s. However, the use of patch connectors has only recently begun and has gradually been paid attention to by manufacturers. This situation is due to the technical difficulties faced by the SMT connector and the failure to realize that the patch connector can effectively save the area of the board. As people discovered that the patch process can improve production efficiency and reduce costs for manufacturers, it can also reduce the area of the circuit board, and improve the flexibility of planning, so that patch connectors can be widely used.

  SMD connectors are divided into: horizontal paste connector (SMT) and vertical paste connector (DIP). SMT generally mounts no-lead or short-lead surface assembly element equipment. It needs to print solder paste on the circuit board, then mount it through the placement machine, and then fix the equipment through reflow soldering. And DIP welding is the equipment packaged by the direct insertion method, and the equipment is fixed by wave soldering or manual welding.

  The overheating temperature of the patch connector is over 260° for 3-5s. The composition of the patch connector: plastic parts and pin pins. The raw materials of the plastic parts are generally PA6T and PA9T, both of which are high temperature resistant materials. Patch connectors are generally used in highway cameras, three-dimensional DC fans, smart electronics, air conditioners, high-definition LCD TVs, notebook computers and other fields. In the meantime, the raw materials of Pin are generally brass, bronze, phosphor bronze and so on. The plating layer is generally gold-plated (semi-gold) or tin-plated. The function of the coating of the pin needle is to resist oxidation, improve the conductive function, and improve the transmission speed of the signal.
