Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment production, in particular to a welding jig. Background Art

[0002] In the production of electronic equipment, welding jigs are one of the essential tools. Welding jigs can fix electronic components to prevent them from moving and ensure that the position of components will not shift during the welding process. At the same time, welding jigs can help the welding gun align with the pad to ensure accurate alignment during welding, thereby improving welding quality and production efficiency.

[0003] Since the components of electronic equipment are relatively small, it is difficult to position them quickly and accurately during manual soldering. Therefore, during the soldering process, different components are usually soldered together one by one manually, which is time-consuming and labor-intensive, and cannot achieve soldering consistency, which is not conducive to improving the pass rate and product quality standards.
