Definition of Thermal Shock Test
Thermal Shock Testing is often called Temperature Shock Testing or Temperature Cycling, high and low temperature thermal shock testing.
According to GJB 150.5A-2009 3.1, the temperature shock is a sharp change in the atmospheric temperature around the equipment, and the temperature change rate is greater than 10 degrees/min, which is a temperature shock. MIL-STD-810F 503.4 (2001) holds a similar view.
Purpose of Thermal Shock Test
The purpose of temperature shock test: the engineering development stage can be used to find product design and process defects; the product finalization or design appraisal and mass production stage are used to verify the product's adaptability to the temperature shock environment, and provide a basis for design finalization and mass production acceptance decisions ; When used as an environmental stress screening application, the purpose is to eliminate early failures of the product.
