Soldering components requires plugging in one by one and one-handed operation, which is difficult, has high welding risks and low efficiency.

[0003] There are also automatic tinning machines on the market that can add tin in batches. However, since the automatic tinning machines have multiple tinning channels, they have strict requirements on the placement and fixation of the entire PCB board and components. Usually, batch tinning will cause PCB board components to collide.

[0004] For example, Chinese patent CN218217870U discloses a tinning jig for sensor production, which has magnetic pressure strips. The number of pressure strips used can be selected according to the required degree of fixation to ensure that the PCB board and the base plate are firmly fixed.

[0005] However, when producing different types of draw-wire sensors, the device needs to replace different tinning jigs, and the screws need to be removed when replacing the jigs, which is inconvenient to replace and affects the production efficiency of the draw-wire sensors.

[0006] For this reason, we urgently need to provide a tinning jig for the production of pull-wire sensors. Utility Model Content
