  • Automatic circuit board test system and automatic circuit board test method applied therein
    Patent number: 11162997
    Abstract: An automatic circuit board test system includes at least one switch module of board under test connected with a test board, a control module and a test process module. The test board includes a first signal interface, a second signal interface and a third signal interface and a repeater. The second signal interface and the third signal interface are mutually connected by a signal cable. The first signal interface is connected with the repeater. The at least one switch module of board under test is connected with the second signal interface and the third signal interface. The control module is connected with the at least one switch module of board under test. The control module controls the at least one switch module of board under test. The test process module is connected with the control module and the first signal interface by at least two serial port buses.
