What is a patch connector?

There are various types of connectors, which can be divided into circular connectors, rectangular connectors, square connectors, customized connectors, etc. according to their appearance. Terminate according to the contact body: crimping, welding, winding; Fix with screws (caps); According to the connection method, it can be divided into: board to board connectors (B to B), line to board connectors (W to B), and line to line connectors (W to W). Today we will talk about patch connectors in wire to board connectors.

Surface welding and mounting technology has been used by some manufacturers since the 1950s. However, the use of patch connectors has only recently begun and is gradually being taken seriously by manufacturers. This situation arises from the technical challenges faced by SMT connectors and the failure to recognize that SMT connectors can effectively save board area. As people find that the patch process can improve the production efficiency and reduce costs for manufacturers, reduce the area of the board road, improve design flexibility and other characteristics, which makes the patch connector widely used, Dongguan Lizhou Electronic Technology Co., Ltd. is a professional manufacturer of board to board, wire to board, wire to wire and other connectors.

Patch connectors are divided into: horizontal patch connectors (SMT) and vertical patch connectors (DIP). SMT generally involves surface mounted components without pins or short leads. It requires printing solder paste on the circuit board, followed by mounting through a SMT mounting machine, and then fixing the components through reflow soldering. DIP welding, on the other hand, involves direct insertion of packaged devices, which are fixed by wave soldering or manual soldering.

The temperature of the SMD connector exceeds 260 ° C for 3-5 seconds. The composition of SMD connectors: plastic parts and n pins. The materials of plastic parts are generally PA6T, PA9T, and LCP, all of which are heat-resistant materials. SMD connectors are generally used in various fields such as highway cameras, stereoscopic DC fans, air conditioners, high-definition LCD televisions, laptops, etc. The material of Pin is generally brass, bronze, Phosphor bronze, etc. The coating is generally gold (semi gold) or tin plated. The coating function of the Pin needle is to resist oxidation, improve conductivity, and increase transmission speed.
