Reliability Highly Accelerated Life Testing Highly Accelerated Stress Screening Test Chamber
HALT implementation steps
Stress exploration: Apply stresses such as temperature (cold → heat → shock), vibration (uniaxial → multi-axial →
compound vibration), and voltage fluctuation in stages, and record the failure threshold.
2. Failure Analysis: Defects are located through high-speed thermal imagers and microfocus CT, and FRACAS (Fault
Reporting and Analysis System) reports are generated.
3. Design Correction: Optimize material selection and structural redundancy design based on failure data.
