Abstract

The invention provides a testing device and an automatic testing method thereof. The testing device is used for testing a circuit board to be tested. The testing device comprises a mainboard, a detection unit and a control circuit, wherein the detection unit is used for detecting whether the circuit board to be tested is in a preset position or not; if the circuit board to be tested is in the preset position, providing a detection signal by the detection unit; and coupling the control circuit to the detection unit and the mainboard and controlling the mainboard to start up by delaying a preset time according to the detection signal so as to test the circuit board to be tested.

Description

technical field [0001] The present invention relates to a testing device, and in particular to a testing device and an automatic testing method thereof. Background technique [0002] During the production and maintenance of various boards such as display cards, it is often necessary to place them on a test machine and run these boards to check whether they can operate normally. [0003] The test machine can be equipped with a normal and good motherboard, so that the board to be tested can be inserted on the motherboard. After the board to be tested is inserted into the motherboard, the motherboard can be run to test the performance of the board. [0004] In the current technology, usually after the board is put into the testing machine, the operator turns on the power switch of the testing machine, presses the power-on switch of the testing machine, and turns on the main board. After the test is completed, the operator needs to shut down the motherboard, disconnect the powe...
