UDP Test Suite
The UDP Test Suite is used by design engineers, quality assurance engineers and testers to find and fix bugs in their UDP implementation. The tests help ensure that the UDP implementation is sufficiently robust so that it is not vulnerable to the wide range of attacks in today's Internet. The tests make use of the Maxwell Pro network emulation environment, so that each test sequence can intelligently impair all aspects of the UDP protocol.

Adjustable Press Plate Bed of Nails Testers
Protector Adjustable Family
Designed for testing heavy massive boards. Boards with heavy components like large transformers and inductors can destroy normal test fixtures. This design utilizes a 3 plate system where an internal lever actuated sub plate containing the test pins raises to probe the circuit board when the handle is pulled. Heavy boards can bend and break exposed test pins. Similarly large boards which need to be probed by very small delicate test pins can also benefit from this protected test fixture design. This fixture is recommended in situations where there is a high board mass to pin size ratio and pin protection is required. Front and rear panel modular inserts allow for easy updates and customizations to the user hardware interface.

Design for Test
Test Coach offers Design for Test (DFT) consulting to assist customers with design review of prototype boards prior to release for production. Design for Test analysis is extremely important in ensuring that an assembly will achieve the highest possible test coverage. For ICT, this DFT will review the board to confirm that the bed-of-nails test fixture can be fabricated to test an assembly without sacrificing test coverage. As with ICT, Flying Probe benefits from DFT analysis by reviewing test point access and mechanical challenges that may affect the potential test coverage. Completing a DFT enables Test Coach to make recommendations to our customers that may be implemented on boards during the design phase which will allow for the most comprehensive coverage at time of test.

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 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).
