A Breadth of Projects

With the new year upon us, it is often a time for reflection on the past. Intrinsic Quality has been in the business of In-circuit test and functional test development for over 25 years. During this time we’ve completed a wide variety of projects, from small fixtures to large rack based test stations. These projects have been utilized by major manufacturers in the automotive, medical, computing and entertainment industries.

Intrinsic Quality: Teradyne and Genrad In-Circuit Testers ICT:

Our ICT projects have included development for Teradyne and GenRad testers.  With our decades of experience, Intrinsic Quality has used a wide range of In-circuit test technologies.

ICT with Opens XpressThe fixture above utilized OpensXpress (framescan) for the testing of integrated circuits and microcontrollers mounted on the PCB (printed circuit board).

Intrinsic Quality ICT 2FlashRunner Flash Device Programmer:

This fixture utilized a FlashRunner programming engine for the programming of flash devices mounted on the DUT (device under test).

Intrinsic Quality has also produced a breadth of functional test solutions, ranging from complex PC integrated test stations, to simple semi-automated testers.Video BarnOwl Functional Tester

This tester to the right utilized Intrinsic Quality’s BarnOwl, a standalone microcontroller powered functional tester. This implementation included a video camera and a small monitor for the operator to confirm that the LCD display on the DUT was functioning. A camera was positioned underneath the probe plate with an aperture cut in it. The circuit board being tested was a water softener control board.

The BarnOwl technology has also been used in high voltage testing applications, as shown below. To ensure operator safety, a thick plexi-glass enclosure was designed. High Voltage BarnOwl Functional TesterThis tester also used Feasa LED analyzers for testing the color and brightness of the LEDs on the DUT. Solenoid actuated push buttons were used to test the functionality of buttons on the DUT and pins inside of alligator clips were used to connect test resources to a block connector on the DUT. A touch-pad was implemented for the operator to enter ID codes. The device being tested was a humidifier control board.

Air Pressure Functional TesterThis tester above was used to test an air pressure transducer board. To ensure that the DUT was correctly converting the input air pressure to a set voltage, Intrinsic Quality engineered a variable air pressure input to check that the DUT responded correctly a variety of pressure ranges. Operator information was displayed with an LCD screen.

PC Based Functional Tester

Intrinsic Quality also creates PC based test stations. These functional testers are often implemented for universal testing, with exchangeable fixtures.

Semi-Automated Functional Testers:

Not all of Intrinsic Quality’s testers are this involved – Intrinsic Quality also makes simple, semi-automated functional testers as requested by our customers.Semi Automated Functional Tester

This semi-automated tester on the right used panel meters (visible along the back) to display test measurements from the DUT for the operator to make pass/fail decisions.

The convenient microcontroller powered tester below precedes through different test steps at the press of its large green button. Different LEDs displayed whether the test is in progress, has failed or passed.Convenient Sized Simple Functional
