Two-Zone Thermal Shock Test Chamber – High-Speed Temperature Cycling
Compliant Standards
Our Two-Zone Thermal Shock Test Chamber meets rigorous international and industry-specific standards, including:
- GB/T 2423.22 (Chinese National Standard)
- IEC 60068-2-14 (International Electrotechnical Commission)
- MIL-STD-202 (US Military Standard for Electronic Components)
- MIL-STD-883 (US Military Standard for Microcircuits)
- JESD22-A104 (JEDEC Standard for Temperature Cycling)
- GJB 150.5 (Chinese Military Standard)
- EIA-364-32 (Electrical Connector Thermal Shock Testing)
Applications
This chamber is widely used for validating product performance under extreme temperature fluctuations in:
- Electronics & Semiconductors: PCB soldering integrity, IC packaging defects, passive components, connectors, and consumer devices (e.g., smartphones, batteries).
- Automotive: ECU, sensors, LED lights, plastic components, and other parts subjected to seasonal temperature variations.
- Aerospace & Defense: Avionics, military communication equipment, weapons systems, and material reliability under rapid descent/ascent conditions.
- Research & Quality Assurance: Material development, prototype validation, and compliance testing in certified laboratories.
Key Features
- Ultra-Fast Transition Time: Achieves temperature switching in ≤10 seconds (exceeding the ≤15s requirement per GB standards), delivering intense thermal shock effects.
- Extreme Rate of Temperature Change: Samples are directly exposed to stabilized extreme environments, ensuring a significantly higher temperature change rate compared to conventional rapid-rate chambers.
- Rapid Temperature Recovery: Both high and low temperature zones remain stable at all times, enabling quick recovery after each test cycle and ensuring high testing efficiency.
- Energy-Efficient Design: Unlike three-zone chambers, the two-zone design eliminates the need for large pre-heating/pre-cooling zones, reducing power consumption and offering a compact structure.
- Superior Testing Accuracy: A fully sealed chamber minimizes thermal exchange, ensuring exceptional temperature stability and repeatability.
- Advanced Construction:
- Inner Chamber: Fully welded SUS#304 stainless steel (1.2mm thick) for durability and corrosion resistance.
- Outer Casing: 1.5mm cold-rolled steel with anti-scratch brushed, polished, and painted finish.
- Insulation: 100mm thick polyurethane foam for maximum thermal efficiency.
- Sealing: Double-layer silicone rubber door seals.
- Observation Window: Multi-layer tempered glass with built-in heating wire to prevent frost formation.
- Safety & Control Features:
- Programmable timer, over-temperature protection, power-cut alarm, data logging, emergency stop, and test duration display.
- Customizable testing programs and optional real-time monitoring capabilities (with intermediate zone return).
