Abstract

The invention discloses an electronic circuit hardware fault rapid judgment method, which comprises the following steps of 1, performing induction and classification on electronic component types andcommon damage reasons on an existing circuit board to form a refined classification table; and 2, in combination with the refined classification table, performing item-by-item judgment on the electronic components on the to-be-repaired circuit board to find out fault points. According to the method, the vulnerable and perishable electronic components are refined and classified, and then the traditional maintenance technology is combined, so that the problems can still be effectively maintained and found and the faults can be solved under the conditions of no circuit diagram and no technical support.

Description

Technical field[0001]The technical field of circuit board fault detection of the present invention specifically relates to a method for quickly judging electronic circuit hardware faults.Background technique[0002]The circuit board is mainly composed of a substrate and pads, vias, mounting holes and components on the substrate. The corresponding pins of the components are soldered to the pads at the corresponding positions on the substrate. After the circuit board is manufactured or in the process of using the circuit board, various faults often occur, and fault detection, analysis, and maintenance are required; traditional maintenance technicians In the case of irregular maintenance and unclear thinking, the purpose of repair is basically achieved by replacing electronic components. The objective disadvantage is that the repair time is long and the repair rate is low.Summary of the invention[0003]In view of the above-mentioned technical deficiencies, the purpose of the present inven...
