Abstract

The invention is applicable to the technical field of circuit boards, and provides a circuit board detection method and device which are used for detecting whether each function module of a circuit board with a micro control unit is normal or not in function. The circuit board detection method comprises the steps of sending a detection instruction to a micro control unit of a circuit board to be detected so as to enable the micro control unit to control each function module of the circuit board to be detected to respond to the detection instruction according to the detection instruction; receiving response data sent by the micro control unit, wherein the response data is generated by each function module of the circuit board to be detected by means of responding to the detection instruction; and judging whether the circuit board to be detected is normal or not in function according to the response data. The circuit board detection method can adapt to functional detection for various types of circuit boards, and reduces the test cost. In addition, the circuit board detection method is also simple to operate, can improve the detection efficiency and has high practicability.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a method and device for detecting circuit boards. Background technique [0002] After the electronic circuit board is mounted, it is necessary to check the correctness of each main component of the circuit board to ensure the normal operation of the function of the circuit board. Traditional circuit board test methods are mainly divided into two types: the first test method is: make a set of production tooling, and then make enough connections, contacts, thimbles, test counterparts, and cooperate with the detection program of the host computer to test the electronic components. The components of the circuit board are tested, and the upper computer is used to display whether the function of the circuit board is normal; the second test method is: when the circuit board is produced, first burn the test firmware into the main control MCU for system self-test, and then cooperat...
