H+W Test Products has designed a series of fixtures for Bi-Level testing.  This system is used on combinational testers for concurrent functional/In-circuit board testing, using a single fixture.  This process lowers fixture cost, speeds testing, reduces UUT handling, and offers a 50% reduction in fixturing.  All H+W Test Products are backed with our "Test-Assured" TM one year warranty in writing and SAME DAY SHIPMENTS.
