Abstract

The invention provides a PCB-based short-circuit fault location system. The system includes a DC power source connected to a PCB under test and a thermal image processing device. The DC power source is used for performing DC power supply on a tested power supply circuit in the PCB under test. The thermal image processing device is used for monitoring the real-time thermal imaging of the PCB undertest after instant power-on, and locating a short-circuit fault through an over-temperature condition in the real-time thermal imaging. According to the invention, the short-circuit fault of the PCB can be quickly located.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a PCB-based short-circuit fault location system. Background technique [0002] With the development of electronic information technology and the popularization of the Internet, electronic equipment is closely related to our lives. Both end users and R&D manufacturers are facing the possibility of electronic equipment failure. The short circuit fault of PCB (Printed Circuit Board, printed circuit board) board still accounts for a large proportion in the fault maintenance of electronic equipment, and usually, the difficulty of repairing the short circuit fault of PCB board is very great. If it is difficult to repair, it must be scrapped and replaced with new motherboard accessories to achieve the purpose of continued use. [0003] There are many reasons for the short circuit of the PCB board, such as static electricity, mechanical damage, deformation of the motherboard body, exc...
