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.

Actuation Methods for Functional Test Systems
-
Functional test typically applies full operational power to a final product or a loaded printed circuit board in order to determine if the Product/ PCB 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 within its Signature Series functional test fixtures.

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.

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.
