Background technique

PCB circuit board is the carrier of electronic components and one of the important components of the electronics industry. After the PCB blank board goes through the SMT upper part and DIP plug-in, the electronic components are welded to the PCB blank board to obtain the PCBA. After welding is completed, it is often necessary to test the welding strength of electronic components to check whether the component welding is stable and whether the welding strength reaches the standard. If the welding strength is found to be low, the welding process should be adjusted in time to avoid producing PCBA boards with easily loose components, which will affect product quality.

In the prior art, there is already a device that can detect the welding strength of components on a circuit board. The circuit board is fixedly placed on a testing platform, and a thrust meter is used to detect the welding strength of the components on the circuit board. However, most of today's circuit boards have irregular bottom surfaces and cannot be placed flat and fixed on the inspection platform for inspection, making inspection difficult and the results inaccurate. Especially when the double-sided circuit board needs to be inspected, it not only increases the difficulty of fixing, but also easily causes damage to the components on the other side when inspecting one side, making the inspection results inaccurate, making inspection more difficult for workers, and reducing the cost of inspection. Efficiency and accuracy.
