  • Line Automation Test Systems

    5000 Series - Circuit Check, Inc.

    The Circuit Check 5000 Series In-line Handler is an integrated inline solution that combines automation, fixturing and measurement hardware in addition to other in-line PCBA probe based test stations, while adding a standardized quick change fixture interface. The 5000 series in-line is a unified solution that is software and hardware agnostic, enabling adaptability to a variety of off-the-shelf lower cost ICT, flash and functional test software and hardware.

  • In-Circuit Test Fixtures

    Circuit Check, Inc.

    Circuit Check’s bi-level and multi-stage fixtures combine multiple test levels in a single fixture using controlled actuation and selected probe travels for powered and unpowered tests.

  • 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.

  • In-Circuit Test Fixtures

    Actuation Methods - Circuit Check, Inc.

    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.

  • In-Circuit Test Fixtures

    Drop-In - Circuit Check, Inc.

    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.

  • In-Circuit Test Fixtures In-Line / Board Handler

    Circuit Check, Inc.

    Circuit Check’s in-line board handler fixturing exceed the high performance requirements associated with high-volume production.  Circuit Check supports in-line fixturing for all the leading ICT handlers including Circuit Check’s AFS5500, Keysight 5i, Teradyne TSh Multi-Site, IPTE and Pematech.  Circuit Check is the go-to partner for in-line functional test fixtures to speed production throughput.

  • Test Systems Test Software

    Circuit Check, Inc.

    With many years of experience solving real world applications, Circuit Check has acquired extensive software expertise.  Our attention to code quality and optimization, as well as our internal code review process, ensures our customers receive efficient and readable code. Below is a brief description of our software expertise:

  • Test Fixture Adapters

    Circuit Check, Inc.

    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.

  • Topside Probing In-Circuit Test Fixtures

    Circuit Check, Inc.

    A patented vacuum alternative was introduced with the Performance Grade product line which incorporates attributes of the Pinnacle pneumatic drive fixture. This vacuum box uses Circuit Check’s Auto Align technology to accurately register the top side probes with the bottom side probes for repeatedly.  Top side test pads down to 0.018″ can be contacted, while bottom side test pads of 0.016″ are supported.

  • Drop-In Functional Test Fixtures

    Circuit Check, Inc.

    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.

  • FEA and Strain Gauge Testing

    Circuit Check, Inc.

    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.

  • Functional Test Fixtures

    Wireless - Circuit Check, Inc.

    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).

  • Functional Test Fixtures

    Multi-Stage - Circuit Check, Inc.

    Multi-Level fully pneumatic fixtures provide the broadest array of in-circuit testing options, allowing powered, non-powered and functional tests to be performed. Often, active component cooling is required during functional testing and Vortex cooling is suited for this style fixture. Additional testing can be achieved with insertion of interposer cards into connectors for through connector testing. Conventional probe spacing of 100 – 39mil and socket-less spacing of 75 – 31mil are available.
