TEMPERATURE AND HUMIDITY TESTING CHAMBERS

Temperature and Humidity Tests are designed specifically to accelerate the aging of products under test. Higher temperatures (50° C and above) and higher humidity settings (60 -95%) can be programmed using environmental chambers.

Temperature and Humidity, with Bias Tests

Common tests conditions for Temperature and Humidity testing are 30 C / 60% rH,85 C,85% rH, and 70 C to 85% rH. During these stress tests, the samples are subjected to 500,1000 and more hours of these severe environmental conditions. For extended test durations, samples may be removed every 100,250,500 and 1000 hours to undergo strict visual functional and electrical testing.

 

Failures in the factory would then be recorded (in terms of yield), and if the batch shows a major failure after these tests, the entire batch is recalled and redesigned with more resilient component materials or robust moisture resistant housing. The factory failures typically save companies 80% to 90% of costs as compared to field failures, whereby the brand of the product may be severely tarnished.

Temperature and Humidity Bias

Temperature and Humidity Bias adds electrical bias to further accelerate the failure modes in time, therefore predicting product/design failure in a much reduced time frame.Biasing for temperature humidity is normally limited to a maximum of 100V and low to negligible power dissipation.
