As electronic products continue to evolve toward higher performance, miniaturization, and greater integration, ensuring their stability under extreme temperature variations has become a critical aspect of product development and quality assurance. The newly launched DHT® Thermal Shock Test Chamber is purpose-built for this challenge—engineered for reliability testing under harsh environmental conditions. It is especially suited for temperature-sensitive components such as circuit boards, semiconductors, and automotive electronics.
Why Is Thermal Shock Testing So Important?
In real-world scenarios, electronic products are often exposed to drastic environmental changes—from intense heat to sudden cold. If the materials or structural designs are not optimized, differences in thermal expansion can easily cause solder joint cracks, delamination, or complete component failure. Thermal shock testing simulates these rapid high-to-low temperature transitions, allowing engineers to detect potential issues early. It’s a proven and effective way to achieve higher product reliability and longer service life.
Key Advantages of the DHT® Thermal Shock Test Chamber
-
Multiple Configurations to Meet Various Testing Needs
The DHT® chamber is available in a wide range of capacities from 27L to 1000L, covering everything from miniature electronic parts to large industrial components. Users can choose the appropriate model based on the size of their products and testing frequency.
Additionally, DHT® supports Air-to-Air thermal shock systems, offering realistic thermal stress simulation along with excellent temperature control efficiency—an ideal solution for high-reliability testing.
-
Efficient Testing with Two-Zone or Three-Zone Structures
The chamber features a vertical dual-zone or triple-zone layout, enabling rapid transfer of specimens between independently controlled hot and cold chambers:
-
Dual-zone models support a basket load of up to 20 kg
-
Triple-zone models can accommodate up to 50 kg
A ball-screw-driven basket transfer system ensures smooth, stable movement, guaranteeing accurate and repeatable results without operational disruption.
-
Wide Temperature Range for Versatile Applications
-
Hot zone: +50°C to +220°C (upgradable to +250°C)
-
Cold zone: -80°C to +70°C
This broad temperature range meets a variety of industry standards and custom testing protocols, making it suitable for consumer electronics, military-grade components, automotive electronics, and more.
-
Intelligent Control System for Ease of Use
Equipped with a PLC programmable controller and user-friendly touchscreen interface, the chamber allows pre-programmed test cycles and fully automated operation. No manual intervention is required, ensuring test consistency and delivering reliable, traceable data.
-
Optimized Airflow for Uniform Temperature Distribution
The internal airflow has been carefully engineered to maintain a temperature deviation within ±0.5°C, eliminating localized overheating or overcooling and improving the accuracy of test results.
-
No Compressed Air Required—Simplified Operation
Unlike conventional models, the DHT® chamber is designed to operate without external compressed air, simplifying installation, lowering maintenance costs, and making it ideal for deployment in both R&D labs and production lines.
