[0002] Connectors are also called connectors, which generally refer to electrical connectors, that is, devices that connect two active devices to transmit current or signals. Connector welding is a common way to connect electronic components. It achieves circuit connection by welding the connector to the substrate. The principle of connector welding is to connect the pins of the connector to the pads on the substrate and fix them firmly together through heat and chemical reactions. At present, when welding the connector to the substrate, the staff needs to hold the pins of the connector and align them with the pads on the substrate, and then use the welding tool to perform the welding operation, and then transfer the welded connector and substrate.
