QxQ's Cam-Track allows exceptional mechanical advantage when vacuum or pneumatics are not available. For ICT, this DFT will review the board to confirm that the bed-of-nails test fixture can be fabricated to test an assembly without sacrificing test coverage. In general, the advantages of FEI test fixtures include the separation of the test initialization and destruction from the testing, reusing a known state for more than one test, and assumption by the testing framework that the fixture set-up works. Completing a DFT enables Test Coach to make recommendations to our customers that may be implemented on boards during the design phase which will allow for the most comprehensive coverage at time of test. Arcan Test. For low volume or custom ICT testing, mechanical fixtures can be engineered to meet specific test requirements. This is why ReMaTek has always paid a special attention to the specific requirements of functional testing. Test fixtures also ease test code design by allowing the developer to separate methods into different functions and reuse each function for other tests. While in-line setup is the simplest test fixture to create, it leads to duplication when multiple tests require the same initial data. Another bad practice is a test setup that contains more steps than needed for the test; this is a problem seen in in-line setup. With several features including manual side access, flying leads or probing only specific test points QxQ will work with you to find the correct customized solution. This differs from delegate setup in that the overall setup of multiple tests is in a single setup method where the test fixture gets created rather than each test method having its own setup procedures and linking to an external test fixture. *Complies with IEC 61646, IEC 61215 mechanical load test specification. Tall components on either side of a circuit board, as well as multiple manual side access, is supported with our manual drive fixtures. Often customers will have us first design a single site test fixture that is manually operated. Further types of construction include eccentric roller fixtures, thread grips and button head grips and rope grips. This series of article explains how a designer should go about systematically in designing a work holding fixture. The advantage of a test fixture is that it allows for tests to be repeatable since each test is always starting with the same setup. Mechanical holding apparatuses provide the clamping force via arms, wedges or eccentric wheel to the jaws.
