” Environmental Stress Screening System ,” also known as ” temperature and humidity chamber vibration comprehensive ” , this series of products for environmental stress screening (Environmental Stress Screening ESS to find and remove the bad parts of products, components, process defects and to prevent Early failure, a series of tests done under environmental stress. It is a type of reliability test and a process in the product manufacturing process. Studies have shown that the screening effect of high and low temperature cycles depends on four aspects: high and low temperature settings, high and low temperature retention time, temperature change rate and number of cycles. Increase the temperature change rate, the effect is better. If there are many components in the equipment, the number of cycles should be increased. The random vibration screening effect is better than the swept frequency sinusoidal vibration, and the vibration stress is stronger without causing damage to the product, so the effect is good. So it is widely used in aerospace -day products, high-speed trains, military equipment, information and electronic instrumentation, advanced composite materials, electrical, vehicles, metals, automotive electronics, electronic vitality of all kinds of products at low temperature or high humidity vibration environment Environmental stress screening test.
Environmental Stress Screening System (ESS), also known as “Temperature and Humidity Vibration Comprehensive Test Box”, is suitable for a series of environmental stress screening (ESS) tests under environmental stress to detect and eliminate undesirable parts, components, process defects and prevent early failure. It is a type of reliability test and a process in product manufacturing. The results show that the screening effect of high and low temperature cycles depends on four aspects: the setting values ​​of high and low temperature, the holding time of high and low temperature, the rate of temperature change and the number of cycles. It is better to increase the rate of temperature change. If the number of components in the equipment is large, the number of cycles should be increased.Random vibration screening effect is better than sweep sinusoidal vibration, without causing damage to the product, vibration stress is stronger, then the effect is better. Therefore, it is widely used in aerospace products, high-speed trains, military equipment, information electronic instruments , advanced composite materials, electricians, vehicles, metals, automotive electronics, and various electronic components to carry out environmental stress screening tests under high-temperature or humid-thermal vibration environment.automotive electronics, and various electronic components to carry out environmental stress screening tests under high-temperature or humid-thermal vibration environment.automotive electronics, and various electronic components to carry out environmental stress screening tests under high-temperature or humid-thermal vibration environment.
