Industry Applications and Typical Cases
1、The electronics and semiconductor industry
Chip reliability verification
The scenario involves switching IC chips from -65℃ (low-temperature chamber) to +150℃ (high-temperature chamber) within 10 seconds, repeating this cycle 1,000 times to test for solder joint cracking and delamination of the packaging material.
Standards: JEDEC JESD22-A104 (Temperature Cycling), MIL-STD-883 (Military Standard).
2、PCB Weather Resistance Test
The scenario involves subjecting the circuit board to repeated temperature shocks between -40℃ (for 30 minutes) and +125℃ (for 30 minutes) to test for copper foil fractures in through-holes and substrate deformation.
3、Testing of complete consumer electronic devices
Case: The mobile phone was rapidly raised from -40℃ to +85℃ (simulating the transition from the cold outdoors to intense heat inside a vehicle), to verify display anomalies and battery performance degradation.
Automotive and aerospace fields
1、Safety testing of power batteries
Scenario: The new energy battery pack undergoes 100 cycles of temperature shock from -40℃ (1 hour) to +60℃ (1 hour), to assess the risk of electrolyte leakage and shell seal failure.
Standard: GB/T 31467.3 (Environmental Adaptability of Lithium-ion Battery Packs)
2、Sensor accuracy calibration
Case: A 15-second switch of the automotive pressure sensor from -55℃ (low-temperature chamber) to +150℃ (high-temperature chamber) to verify whether the temperature drift error exceeds the standard (such as ±0.5% FS).
3、Limit verification of aerospace components
Application: Test the structural fatigue of satellite solar panel materials under the impact of -120℃ (in the shadow of space) to +120℃ (direct sunlight).
Material and component manufacturing
1、Research on aging of polymer materials
Scene: The rubber sealing ring is rapidly switched between -70℃ and +200℃, and the changes in elastic modulus and the phenomenon of embrittlement and cracking are observed (300 cycles).
2、Metal coating adhesion test
Case: After 50 cycles of impact between 50°C and 150°C, the area of coating peeling off on electroplated hardware parts is inspected (if it is ≤ 5%, it is qualified).
3、Phase change analysis of chemical materials
Application: Study the shift of glass transition temperature (Tg) of epoxy resin under sudden temperature changes (-30℃ ↔ +180℃).
Key points for scene selection
When purchasing equipment, it is necessary to match the specific scene requirements:
1、Temperature range:
Automotive electronics typically operate within the temperature range of -40°C to +150°C, while aerospace materials need to function in a range of -70°C to +180°C.
2、Switching speed:
Military standards require ≤ 10 seconds, while for consumer electronics, it can be relaxed to ≤ 15 seconds.
3、Volume requirement:
50L inner box for testing small PCB boards, and 1000L or larger custom-made inner boxes for automotive battery packs are needed.
4、Meet the standards:
IEC 60068-2-14 (Electronics), SAE J2638 (Automotive), GJB150.5A-2009 (Military Industry)
Usage Precautions
1、Installation Environment
The temperature should be maintained between +5℃ and +25℃, with a 50cm clearance around for heat dissipation.
2、Power Supply Requirements
Three-phase 380V ± 10% voltage, independent grounding (resistance < 4Ω), power 12 - 30kW (depending on model) .
3、Safety protection
Multiple safety mechanisms such as over-temperature protection, compressor overload protection, and leakage circuit breaker, etc.
