High Node Count In-Circuit Test Fixtures
HNC Test Fixture
Circuit Check continues to be a leading edge provider of custom engineered test solutions with our new Keysight i3070 HNC test fixture. Working with Keysight Technologies during the development of their HNC adapter in 2011, we were the first test fixture provider to offer customers with a solution to test large node count boards. High node count test fixtures can handle greater than 10,000 probes.

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.

Benchtop Test System
300 Series Benchtop ATE
The Circuit Check 300 Series benchtop ATE Test Platform with built-in professional fixturing solves the uncertainty of repeatable results that are common with bench testing. With the 300 Series Benchtop ATE, test procedures can become automatic, with test steps and go/ no-go limits easily programmable in common tabular form. Hand-probing is eliminated, replaced with accurate, repeatable tooling and reliable spring-loaded test probe fixturing.

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.

Military & Aerospace Solutions
Military and aerospace electronics spans a vast array of complex applications, including communications, vehicle control, radar, electronic warfare and countless others. Although the applications are widely varied, there are similarities in the requirements as well. Typically these electronic systems, whether COTS (Commercial Off- the-Shelf) or custom developed for the application, share similar requirements for ruggedness, reliability, and precision. Our customers don’t have room for error, mission critical hardware test systems must perform as designed. Circuit Check provides military and aerospace testing solutions for ITA’s, Self-Test Fixtures and Automated Test Systems that meet the stringent needs of this marketplace.

Wireless In-Circuit Test Fixtures
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.

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.

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.
