[0001] The utility model relates to the technical field of welding jigs, in particular to a welding jig for multiple electronic components. Background Art

[0002] During the production process of PCB boards, electronic components need to be soldered on the substrate. Therefore, a soldering fixture is needed to fix the electronic components and the substrate to limit the relative movement between the electronic components and the substrate, which facilitates the soldering of the electronic components.

[0003] Publication No. CN215034815U provides an electronic component soldering jig, which has the characteristics of good fixing effect and is easy to disassemble and replace the pressing plate to adapt to different electronic components. However, in the production process, the jig needs to unscrew the clamp arm and install a new PCB board and then tighten it to clamp and fix it after each soldering. The operation is relatively complicated, resulting in a relatively low soldering efficiency of the jig. To this end, we propose a multi-electronic component soldering jig. Utility Model Content

[0011] By adopting the above technical solution, the PCB board is pushed upward by the abutting push plate passing through the jig frame and abutting the solder template to complete the clamping and fixing.

[0012] Specifically, the placement plate slides inside the jig frame through the limiting frames on both sides, and the placement plate is clamped or drawn out of the jig frame by a rotating clamp installed rotatably on the side wall against the limiting groove.

[0013] By adopting the above technical solution, the placement plate can be pulled out and fixed in position in the jig frame through the limit frame and the rotating clamp, so that the PCB board can be easily replaced.
