  • Wireless In-Circuit Test Fixtures

    Circuit Check, Inc.

    Higher density more complex circuit boards complicate testing requirements while 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 standard long wire fixtures. Wireless fixtures replace the “nest” of wires with copper traces on a multilayered printed circuit board called a Translator Board or T-Board®. Circuit Check’s wireless fixture technologies reduce test program debug and maintenance times while easing the ECO process. Thus allowing for the higher level of test performance, the ability to probe smaller denser targets and achieve ultra-high node counts.
