Background

Wave soldering equipment has been invented for over 50 years, and has the advantages of high production efficiency, high yield and the like in the manufacture of circuit boards of through hole components, so the wave soldering equipment is the most main welding equipment in the automatic mass production of electronic products. However, there is also a limitation in its application, namely, the welding parameters are different. The soldering parameters required for different solder joints on the same circuit board may be quite different due to their different characteristics (e.g., heat capacity, pin spacing, solder penetration requirements, etc.). However, the wave soldering is characterized in that all welding spots on the whole circuit board are welded under the same set parameters, so that different welding spots need to be mutually connected, and the wave soldering is difficult to completely meet the welding requirement of the high-quality circuit board. In order to solve the technical problem, selective wave soldering technology has been developed, and selective wave soldering is realized by utilizing a numerical control principle through selective wave soldering.

In the welding process, the workpieces such as the circuit board and the like need to be clamped by using the jig, but the traditional jig generally consists of a frame and bolts, and the circuit board is fixed by using the bolts, so that the circuit board or the workpiece is very troublesome to replace each time. Therefore, we propose a selective wave soldering work piece clamping fixture.
