[0002] Currently, in the field of semi-automated PCB board soldering, the main method still relies on fixing the PCB board and then using fixtures to attach various components to the PCB board to complete the soldering of the components to the PCB board.

[0003] However, since the PCB board and each component are fixed separately, misalignment between the PCB board and the components can easily lead to ineffective soldering. At the same time, even if the components are clamped and connected to the PCB board by a fixture, the components may become loose or even fall off.

[0004] Therefore, there is an urgent need to develop a new fixing device and welding system for reflow soldering of plug-in components to solve the technical problems of inaccurate docking of PCB boards and individual components due to the separate clamps and the loosening of components during the docking process.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0029] Research has revealed that current semi-automated PCB soldering primarily relies on fixing the PCB and then using fixtures to attach components to it for soldering. However, because the PCB and components are fixed separately, misalignment can easily occur, leading to ineffective soldering. Furthermore, even when components are clamped and connected to the PCB, loosening or even detachment of components can still occur.

[0030] Based on the above research, this disclosure provides a reflow soldering fixing device and soldering system for plug-in components, which facilitates the soldering equipment to solder the PCB board and each plug-in component, and achieves precise and firm connection between the PCB board and each plug-in component.
