A test jig is an apparatus into which a printed circuit board assembly (PCBA) may be inserted, so that appropriate contacts may be made for in-circuit testing. Typically, the test jig holds the PCBA between an upper and lower test fixture. When the two fixtures are pressed together, ;spring-loaded test pins make contact with test points on the PCBA, thereby allowing test circuitry to perform an in-circuit test of the PCBA.
The Test Fixture Designer module supports designing fixtures for three different generations of test jigs: The Macaos Integrated Test Jig, the Macaos Box Jig, or a legacy jig. You will find the Box and Legacy jigs, as well as a variety of test pins, cables and other accessories, available for purchase from the Global products|Test accessories folder in the Macaos Enterprise Product Browser.
The Test Fixture Designer module imports test pin locations, if they are included in the component layer of the PCBA to be tested.
