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.

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.

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.

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.

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.
