Wireless Fixture Technology

Circuit Check has been designing and fabricating wireless fixtures since the early 1990's and has no equal in the industry. There is no equivalent product that can match the test performance advantages, reduced debug time, ease of ECO's, reduced maintenance, the ability to probe denser smaller targets and ultra high node counts.

Higher density more complex circuit boards complicate testing requirements. Smaller more tightly spaced test pads create a wiring nightmare for the fixture fabricators, test engineers and maintenance personnel.

Wireless fixtures solve issues typically associated with the nest of wires found in long wire fixtures. For over 15 years Circuit Check has been replacing the "nest" of wires with copper traces on a multilayered printed circuit board called a Translator Board (T-Board).

How it works...  cross section of a Wireless Fixture

Circuit Check's Intelligent Automated Routing of sensative signals is controlled during our layout process so they are placed for optimal signal fidelity. This is accomplished by isolating the signal trace between ground planes, using separate power planes or adding "pull-up" resistors or "decoupling" capacitors on the signal traces.

The reduced noise from grounding and crosstalk allows faster signal rebound which is particularly inportant in low voltage applications.

Compared to standard wired fixtures virtually every aspect of the fixturing experience has been improved... a fundamental improvement in the way fixtures are designed, ECO's are performed, fixtures are duplicated and deployed.

Cleaner signals permit the test to run at a faster rate. Programming of flash memory runs exponentially faster, up to full test system speed.

Internal fixture electronics are neater, more compact and are easily designed in during T-Board layout.

For proto-type boards, the enhanced performance of wireless allows fixture anomalies to be quickly ruled out and debugging to be focused on the UUT for design issues reducing overall debug time.

Quicker turn of complex digital tests can be achieved since ground bounce has been virtually eliminated.

Fixture size is kept to a minimum with a lower profile and is up to 35% lighter in weight than conventional wired fixtures.

Wireless fixtures never block resources when compared to shortwire fixtures allowing greater test coverage,

Since there are no blocked resources larger UUTs can be placed on smaller fixtures.

Duplicate wireless fixtures provide identical test performance due to greater stability resulting in a significant cost savings!
