Abstract: An Integrated Automatic Test Equipment that provides the test program development environments and execution of test programs for the assembled Print Circuit Boards. This test equipment includes Microsoft Windows PC executable programs, a digital/analog/SPI test controller, and a JTAG controller for boundary scan test. Both test controllers are attached to PC via USB ports for receiving test commands and replying test results. Test program development allows user to specify the rest stimulus and the expected test response for both digital test and boundary scan test. In addition to perform standalone tests, digital tester and boundary scan tester can drive and detect test signals to and from each other. The combination of digital test function and boundary scan test function can increase PCB production line test fault coverage.
