[0002] SMT connectors are patch connectors. They are divided into two types. According to the different ways of inserting the pin holder into the board, there are vertical and horizontal types. According to the packaging method, there are tape and reel packaging, which can make the connector more convenient to connect with the board end. With the development of the times, connectors have become the few remaining through-hole components on most PC circuit boards. Manufacturers have also found that by reducing or not using mixed welding technology (that is, using surface mount and through-hole components on the same circuit board at the same time), and using all SMT processes, manufacturers can improve production efficiency and reduce costs. The existing SMT connectors are not stable in plugging. When collisions and scratches occur at the joints, the SMT connector connection will be detached, which will affect its use.
