Application of Environmental Stress Screening Chamber
Environmental stress screening chambers are widely used to accelerate the discovery of early failures that may occur in products under extreme environments. They are suitable for all types of electronic, electrical, mechanical and new energy products. By controlling variables such as temperature, humidity, and vibration, these devices can simulate environmental changes that may be encountered in reality. In the field of semiconductors and communications equipment, environmental stress screening helps engineers identify potential solder joint cracks, material aging, or seal failures. Medical device manufacturers use such tests to verify the performance of equipment under transportation, high-temperature storage, or humid environments, while the new energy industry verifies the stability and safety of battery modules by simulating repeated changes in high and low temperatures.
International Safety Standards
Zhongzhi's environmental stress screening Chamber complies with ISO9001-2015, ISO14001-2015, ISO45001-2018 and CE marking requirements based on EU directives.
