Expanding In-Circuit Capabilities
Circuit Check supports reading linear bar codes and 2D symbols within each of its fixture product lines.When spring-loaded probes are not practical or access is limited, Circuit Check can help you with thru-connector tests to contact connectors on any surface or edge of a circuit board. These tests can be implemented spring probes, mating connectors, sacrificial SMT connectors, and stabber cards.

Drop-In In-Circuit Test Fixtures
The Chameleon
The Circuit Check kit called the Chameleon allows easy re-use of a majority of an ICT fixture’s major components. The Chameleon includes a full size probe plate and interface alignment plate so all valuable tester resources are available. The probe plate assembly is held in place with twelve (12) screws and the vacuum box’s interchangeable push plate is easily replaced by removing four (4) shoulder screws.

Actuation Methods for In-Circuit Test Fixtures
Commonly referred to as In-Circuit Test (ICT), loaded board test can be defined as the task of measuring values of components that have been installed on a printed circuit board (PCB). A second basic category of loaded board test measures simple open and shorts on the board to verify manufacturability standards. Circuit Check supports all forms of in-circuit test strategies with its Performance Grade and Value Line test fixtures.

Functional Test Fixtures
Businesses rely on Circuit Check’s functional test fixture expertise. Functional test typically applies full operational power to a loaded printed circuit board in order to determine if the PCBA performs functions as designed. This type of test often involves custom built test equipment and custom test fixturing. Circuit Check supports all forms of functional test strategies.

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).

FEA and Strain Gauge Testing
Circuit Check began Strain Gauge Testing in 1999 when BGA/SMT technology started replacing PTH components, reducing strain levels was a reactive post fixture fabrication process. We quickly recognized that the “reactionary” process was neither efficient nor were we capable on knowing the lowest achievable strain levels. Our engineering team came up with visual tools utilized during design to easily identify areas of excessive probe force, though still not enough data was generated to identify the lowest possible strain. Finite Element Analysis software models the PCBA and test fixture and applies the pressures from test probes and board supports and indicates the micro strain level applied to the PCBA. Using the FEA software during our design process allows our engineers to modify fixture designs to attain the lowest possible micro strain before fabrication begins.

Test Fixture Adapters for In-Circuit Test Fixtures
Circuit Check test fixture adapters are utilized when the target ICT tester is not available or has been replaced with a newer technology tester. The tester adapter will often allow existing test fixtures from one test manufacturer to be utilized on another manufacturer test platform, eliminating the need for replacement fixtures. Contact Circuit Check to discuss your tester and fixture combinations for the best choice of a cost effective solution.
