Problems solved by technology

[0003] The traditional PCB board debugging method mainly uses human eyes to inspect the missing soldering of the main components of the PCB board and the open and short circuits of the circuit. However, this method not only has low detection efficiency, but also has high labor intensity, error-prone, and low accuracy. And it is impossible to see the real problem in the PCB board

Abstract

The invention discloses a PCB testing device and belongs to the technical field of testing devices. The problems that a traditional PCB debugging method is low in detection efficiency, large in labor intensity, low in precision and the like are solved. The PCB testing device comprises an upper mold assembly and a lower mold assembly, wherein the upper mold assembly is arranged above an electric control box, and the lower mold assembly is arranged on an upper panel of the electric control box. Under the effect of a lifting mechanism and an XY axis moving mechanism of the upper mold assembly, a probe on the upper mold assembly is made to penetrate through a probe hole in a probe board of the lower mold assembly, so that the probe makes contact with a product to be tested on a product carrier board for testing the situations such as lack of weld and open-short circuits of main elements of the PCB. The PCB testing device is easy to operate and high in automation degree, simplifies manual operation, reduces labor intensity and improves working efficiency and testing accuracy.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for a PCB board. Background technique [0002] With the advancement of science and technology, the development of the electronic industry is advancing by leaps and bounds, the electronic system is becoming more and more complex, and the reliability and maintainability requirements of the electronic system are also getting higher and higher. As an important part of the development and production of electronic systems, the quality of PCB boards directly affects the quality of the entire equipment, and the long production cycle will affect the debugging progress and delivery time of the whole machine. Therefore, PCB board debugging is an important link related to the quality and production cycle of the electronic system. [0003] The traditional PCB board debugging method mainly uses human eyes to inspect the missing soldering of the main components of the PCB board and the open and s...
