Description

Technical Field

[0001] The utility model relates to the field of welding jigs, in particular to a test probe welding jig. Background Art

[0002] There are two forms of existing test probe welding. One is patch welding, that is, after printing the solder paste, the probe is manually placed so that the probe welding surface is in full contact with the PCB solder point, and welding is achieved through the reflow process. The advantage of this patch welding method is that it can be pasted in batches and reflowed uniformly, which can achieve mass production and is relatively efficient. However, during the reflow process, the solder paste often melts and becomes a liquid flow, which will shift the test probe, and it is impossible to ensure that all the test probe welding surfaces and PCB solder points are vertically welded. Another method is manual soldering with a soldering iron, that is, the operator heats the soldering iron to melt the tin wire so that the probe and the PCB solder point can be welded. This method can basically ensure that the test probe will not shift and can achieve vertical welding, but it requires the operator to manually solder one by one, and the welding efficiency is very low. At the same time, the fullness of the solder joints will also be inconsistent. Utility Model Content
