Cool stuff to work on. Some that I have seen get down to -85 deg C or better and can pull down from room temperature in 30 minutes.

In my corner of the electronic components industry we use temp and humidity cycling to simulate aging.
2000 hours of "85/85" testing (cycling temp and humidity up and down, hot cold, dry humid) simulates
