Test fixture board and testing method adpoted thereto

Abstract

This invention provides a test fixture board and the applicable test method therein, which can unify and simplify the PCBA testing process. The test fixture board includes an uplink connector, a downlink connector, and a programmable main control module. The uplink connector connects to a host computer. The downlink connector connects to the board under test (DUT). The programmable main control module sets up input / output interfaces and multiple communication interfaces, so that the input / output interfaces are coupled to the downlink connector and the DUT through multiple communication interfaces. The programmable main control module executes a test program based on the DUT's test information to generate test results.
