Thermal Shock also is referred to as temperature cycling in some MIL specs. In a thermal shock test, the TE cooler (not powered throughout test) is placed in a hot chamber (for example, 85°C) for a set time (for example, 30 minutes). The part is then transferred to the cold chamber (for example, -40°C) for the same time. This cycle is repeated several times depending on the requirement.
