PCB short circuit inspection method and device

The invention discloses a PCB short-circuit inspection method and device, and the method comprises the steps: (1), extracting the information of all designed short-circuit devices, and enabling the information of the short-circuit devices to comprise the information of a network connected with the short-circuit devices; (2) acquiring the total number of networks connected by all designed short-circuit devices, and acquiring the total number of designed short-circuit categories, and physically defining one short-circuit category by all networks connected into a whole by using the short-circuit devices; (3) comparing the total number of the designed networks and the total number of the designed short circuit types with the total number of the networks and the total number of the short circuit types in an actual short circuit detection report of the PCB; and (4) determining whether the PCB has a non-design short circuit according to a comparison result. According to the invention, the non-design short circuit on
