Printed circuit board (PCB) detection device and method

Abstract

The invention provides a PCB detection device and method, and relates to the technical field of PCB detection. The device comprises a central processing chip circuit, an abnormal state feedback processing circuit and sensor chip circuits arranged in different tested circuit parts of a PCB. In each sensor chip circuit, a temperature detection circuit, a voltage detection circuit and a current detection circuit are integrated; the sensor chip circuits detect operation parameters of the different tested circuit parts of the PCB; the central processing chip circuit determines whether the operationparameters are abnormal; and the abnormal state feedback processing circuit selects a preset feedback processing strategy according to the abnormal operation parameter, and controls and processes thetested circuit part, corresponding to the abnormal operation parameter, of the PCB according to the preset feedback processing strategy. Thus, automatic detection and closed-loop response processingcan be realized for the whole system.

Description

technical field [0001] The invention relates to the technical field of detection of printed circuit boards, in particular to a detection device and method for printed circuit boards. Background technique [0002] With the gradual popularization of technologies such as electronic circuits and communication networks, printed circuit boards (Printed circuit boards, referred to as PCB boards) have been widely used in the field of electronic circuits, such as computers, medical equipment, and various electronic measuring instruments. It needs to be applied to the PCB board. For example, a spectrum analyzer is a very precise electronic measuring instrument, which is mainly used in base station maintenance, electronic product research and development, production and other fields. In various application fields, spectrum analyzers have high requirements for system stability, reliability, and consistency. For some precision electronic measuring instruments such as spectrum analyzers...
