Thermal Shock Test Chamber is developed to meet the greater demands for highly accelerated stress tests (HAST) of electrical and electronic components. The specimen transfer directly between hot and cold zone to achieve rapid product temperature change for thermal shock, also known as Environment Stress Screen test.
Features
- Air-to-air thermal shock test.
- Direct transfer between hot and cold zone vertically with Stainless Steel carrier basket.
- Energy efficient design with Japanese or German technology reduces electricity consumption by 20%.
- Compact footprint, Space saving.
- Programmable.
Standard Compliance
- IEC 68-2-1 Environmental testing – Part 2: Test methods – Tests A: Cold
- IEC 68-2-2 Environmental testing for electric and electronic products Test methods – Tests B: Dry Heat
- MIL-STD-810D Environmental test methods and engineering guidelines
