[0002] Surface Mount Technology (SMT) is also called surface mounting or surface mounting technology. It is a circuit assembly technology that mounts leadless or short-lead surface mount components (abbreviated as SMC / SMD, called chip components in Chinese) on the surface of a printed circuit board (PCB) or other substrate, and assembles them by soldering through reflow soldering or dip soldering.

[0003] During the PCB processing, after one side of the PCB is processed, it is necessary to flip the PCB board to the other side for processing. If the PCB board is flipped manually each time, such operation will not only increase the workload of the staff, but also waste manpower costs. In addition, if the staff makes an error when manually flipping the PCB board, it is easy to cause the PCB board to fall during the flipping process and be damaged by impact. Therefore, it is particularly important to design a flipping machine that can automatically flip the PCB board. Utility Model Content
