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.

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.

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).

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.

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.

New Generation Vacuum Box for the 3070 Test Platform
Vortex Series
-
The Vortex Series is a new generation vacuum box for the 3070 test platform that will easily revolutionize in-circuit test. The simplified and streamlined design allows for maximizing the usable testable board size of the Vortex 100 Performance Grade fixture. The rugged all aluminum design maximizes the opening angle of 85° ideal for Cobot usage, while eliminating the top plate and associated hardware and retaining our classic quick plate guided probe technology.
