TESTING

 

We have the facilities, equipment, and personnel to perform the following testing:

 

· Burn-In:

Power On or Off

Controlled Ambient Temperature

Time Controlled

Design & Fabricated Fixtures

 

· Functional Testing: 

Circuit Cards

Assemblies

Complete Units

Utilizing test procedures and test fixtures and calibrated test equipment.

 

· Environmental Testing: 

Two environmental test chambers that can produce stabilized temperatures in the range of -50 degrees to +150 degrees C.

We have a full service testing laboratory here in the local area that we use for additional testing such as vibration, humidity and altitude tests. 

 

TEST PROCEDURE / TEST FIXTURE DESIGN

 

· Our engineers have considerable experience writing test procedures for circuits that have analog, RF, and digital functions. 

· We can also design and build either manual or automated test fixtures to quickly check for proper circuit operation.
