Background

In the assembly welding process of electronic products, the welding quality directly affects the quality of the whole machine. Therefore, in order to improve the welding quality, in addition to strictly controlling the process parameters, scientific weldability tests are required to be carried out on the printed circuit board, the copper-clad plate and the components.

The solderability test equipment on the market today is generally divided into two categories: one is a simple groove body, and the device is not provided with a sample clamp. Before the test, the sample is marked with immersion scale lines piece by piece, and then is immersed into the welding bath after being clamped by using tweezers or similar tools. When the sample amount is large, the marking of the scale marks needs to be carried out for a long time, and the sample is easy to slip in the manual clamping process so that the sample slides into the welding groove, and when the situation occurs, the sample needs to be prepared again. The second type of device is equipped with a sample holder, which is more expensive than the first pure cell type device in terms of cost, and the holder is usually fixedly mounted on the device and cannot be moved. As the circuit board and the copper-clad plate have more weldability test standards and different standards have different requirements on the immersion depth, the clamp arranged on the equipment cannot meet the requirements of all standards.

Therefore, it is necessary to invent a holding jig for a solderability test sample to solve the above problems.
