Wireless Functional Test Fixtures
-
Circuit Check’s wireless fixture technologies reduce debug time, simplify ECO’s and reduce maintenance. This allows for the highest test performance, ability to probe denser smaller targets and achieve ultra-high node counts. Higher density more complex circuit boards complicate testing requirements. Smaller more tightly spaced test pads create a wiring challenge for the fixture fabricators, test engineers and maintenance personnel. Wireless fixtures solve the challenges associated with the nest of wires found in long wire fixtures. Wireless fixtures replace the “nest” of wires with copper traces on a multilayered printed circuit board called a Translator Board (T-Board).

Drop-In Functional Test Fixtures
-
Circuit Check’s drop-in base fixture and replaceable personalized plates are the ideal solution where production volumes are lower and the need to change from one fixture and test program to another occurs quickly. Interchangeable test fixture drop-ins enable the same test system to be quickly reconfigured with different tooling and probe patterns for different products. This maximizes equipment re-use, while minimizing the cost for each new test. With Circuit Check’s base fixture and drop-ins, the wiring and test electronics are not disturbed, thus ensuring configuration consistency each time the system is re-tooled.

Cable-End Test Fixtures
-
Test Head Engineering's cable-end fixtures are used in the production of cable harnesses and in the testing of finished products. They are the long-lasting "connector" to the test system - taking the place of connectors that would quickly exceed their cycle life and produce erratic test results. Cable-end fixtures are used in the automotive and heavy equipment industries, but are also applicable wherever low cycle-life connectors are used - including RF cables.
