Thermal shock test

 

Introduction to the test project

 

The thermal shock test, also known as the temperature shock test or the high and low temperature impact test, is used to assess the adaptability of the product to the rapid changes in the ambient temperature. It is an indispensable test in the identification test of the equipment design and the routine test in the batch production phase. In some cases, it can also be used for environmental stress screening tests. Electronic products, mechanical parts, and auto parts are subjected to hot and cold temperature impact tests before leaving the factory, and their reliability has been verified.

 

Test parameters

 

Test temperature range, rise/fall rate, number of cycles, exposure time, etc.;

 

Performance impact

 

Surface cracking, joint failure separation, electrical or mechanical failure, etc.;
