However, in actual production, problems of poor electrical signal transmission may occur, mainly because of virtual welding or internal empty welding problems in the welding operation. The welding defects cannot be found by visual inspection after welding is completed, but when vibration or external force pulling occurs, the welding part of the terminal and the PCB may become loose or even separated, which further affects the electrical signal transmission.
