Environmental Testing Room
Outline
GTAC offers a wide range of environmental testing chambers where the temperature and humidity can be precisely controlled to investigate the impact of various environments on electronic products and systems.
Temperature cycling tests are used to test the durability of a package undergoing extreme temperature variations over a given period of time. This test exposes the package to mechanical fatigue induced by cycles of thermal expansion. The dwell period is important because it allows the sample load to reach equilibrium and for stress relaxation to occur.
Humidity cycling and temperature-humidity cycling are used to assess the effect of swelling from moisture absorption on product reliability. The cyclic nature of these tests accelerates damage accumulation from periodic moisture absorption and desorption during changes in environmental humidity.
The bias test is used to test for moisture induced failures. The test requires the devices to undergo a constant temperature, elevated relative humidity, and electrical bias (constant or intermittent, based on device type). Voltage cycling may be required to prevent the device from heating up and preventing moisture effects from occurring.
Our vibration chambers simulate extreme vibration of all sorts of electronics, avionics, telecoms equipment, etc. to replicate the toughest of operating environments.
