When your products are exposed to sudden temperature changes-whether in aerospace launches, automotive start-stop cycles, or military-grade electronics-they must survive without structural or functional failure.
LIB's innovative thermal shock test chambers bring precision, repeatability, and international standards compliance into one system, giving R&D, QA, and certification teams full confidence in their data.
【What Makes LIB Air to Air Thermal Shock Chamber Exceptional for Thermal Durability Testing from –70 to 200 °C】
LIB's air-to-air thermal shock chambers use a two-zone basket transfer system for rapid hot–cold switching.

Standards Compliance
IEC 60068: Thermal shock test procedures
JESD22 : Semiconductor and aerospace components
ISO 16750: Road-vehicle electrical endurance testing
...
With independent hot and cold chambers held at steady preset values, samples experience true environmental shock. This setup precisely simulates outdoor-to-indoor, altitude-change, or launch-stage conditions without manual intervention.
【LIB Air to Liquid and Liquid to Liquid Thermal Shock Chambers Providing Fast, Accurate, and Reliable Temperature Cycling Tests】
When ultimate speed or conductive heat transfer is required, LIB's liquid-based systems immerse or circulate fluids for instant thermal exposure.

Why Fluid-Assisted Shock?
Ultra-Fast Ramp Rates: Heat transfer by fluid (water or liquid ) outpaces air, reaching extreme deltas in seconds.
Dual Tank Configurations: Independent hot (up to +150 °C) and cold (down to –75 °C) baths pre-stabilized for continuous cycling.
Use Cases: Micro-solder reliability, aerospace hydraulic components, polymer composite testing, high-density PCB evaluation.
Standard Support: IEC, JIS, ASTM and other globally recognized methods.
Liquid-to-liquid cycling reveals failure modes such as micro-cracking, delamination, or rapid fatigue that air-based tests may miss-especially valuable in high-density, thermally sensitive electronics.
【LIB Wide Range of Two-Zone and Three-Zone Thermal Shock Test Chambers for Your Needs】
Not every test requires the same approach - that's why LIB designs both two-zone and three-zone thermal shock chambers, giving you a tailored solution for every application. Here's how they compare:
|
|
|
|
|---|---|---|
| Feature | Two-Zone Thermal Shock Chamber | Three-Zone Thermal Shock Chamber |
| Design | Basket-style transfer between independent hot & cold zones | Fixed test area with pneumatic dampers cycling hot & cold air |
| Temperature Switching | Ultra-fast air-to-air transfer within ≤ 3 seconds | Rapid air circulation through pre-heated & pre-cooled zones |
| Temperature Range | –70 °C to +200°C | –70 °C to +200 °C |
| Recovery Time | ≤ 5 minutes | ≤ 5 minutes |
| Chamber Volume | 162 L / 340 L / 500 L / 1000 L | 100 L / 210 L / 300 L / 500 L |
| Best For | Automotive, aerospace, military-grade, PCB stress testing | Large samples, electronics, rubber, plastics, advanced communication equipment |
| Advantages | • Realistic extreme thermal shock • Simulates outdoor–indoor or flight conditions |
• No sample movement • Easier loading for big or delicate products |
| Standards Compliance | IEC 60068-2-14, JESD22-A104... | IEC 60068-2-14, ISO 16750, IEC 61730... |
