Thermal Shock (TS) TST
Represents extreme temperature variations caused by vehicle day-night cycles, abrupt regional climate changes, and prolonged parking.
Test Description

AQG-324/IEC 60749-25:2003 Condition G

Test Objective

Evaluates mechanical fatigue caused by mismatches in coefficients of thermal expansion (CTE) between different materials (e.g., solder joint cracking, delamination).
