Rotary Table Handler
6000 Series Rotary Handler
-
Rotary table handlers are an excellent choice for PCBA or product – level test, programming, part marking, automatic part rejecting, and vision inspection in order to satisfy manufacturing applications that require high throughput. Rotary table based systems used in production can also help reduce the impact of load and unload times for the operator, because the device-under-test (DUT) automatically moves to the next cell within the station as each DUT is loaded. Circuit Check’s 6000 series handlers are modular, scalable and flexible, supporting high-mix and high-volume production needs. A common application example is to configure a 6000 series as a rotary station to perform simultaneous PCBA bar code scanning, testing, programming and marking, in a pipe-line process which improves throughput requirements. The 6000 series handlers leverage Circuit Check’s unique quick-change fixture drop-in technologies to allow for station modularity and scalability. Production line flexibility is achieved because the 6000 series handler is software and hardware agnostic, enabling adaptability to a variety of applications, and is limited only by the number of stations.

Automotive Solutions
-
One of the most challenging applications in the field of automotive testing is manufacturing electronics. With each successive model year, the number of automated features increases. Every segment of the automotive electronics plays a role in the safety and reliability. These critical applications require high dependability and low maintenance and warranty costs. Our customers don’t have room for error, hardware test systems must perform as designed. Circuit Check provides Automated Test Systems that meet the stringent needs of this marketplace.

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.

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.

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).
