Description

Technical Field

[0002] Circuit board usually refers to printed circuit board, which is a basic component used to support and connect electronic components. Its main function is to provide mechanical support and electrical connection, so that electronic components can be reliably connected and work in the whole system. In the process of circuit board production, detection equipment is usually needed to detect the circuit board.

[0003] Currently, the circuit board detection device on the market is usually composed of a base plate, a support frame, a lifting assembly and a detection needle plate. Among them, a notch with the same size as the circuit board is usually opened on the top of the base plate. The user needs to place the circuit board in the notch, and then operate the lifting assembly to move the detection needle plate downward, so that the detection needle plate can be brought into contact with the circuit board, and then operate the detection needle plate to perform detection on the circuit board. However, because the size of the notch is constant, the device cannot adapt to circuit boards of different sizes, which affects the scope of application of the device. In the production process of circuit boards, electronic components are often welded and fixed on the circuit boards. Improper temperature control may cause poor melting of the solder, which may cause problems on the surface of the circuit board.
