ESS-600-1000温湿度振动综合试验箱又叫做环境应力筛选系统(environmental stress screening（ESS）)，为发现和排除产品中不良零件、元器件、工艺缺陷和防止出现早期失效，在环境应力下所做的一系列可靠性试验，也可以做为产品制造过程中的一道工序。高低温循环的筛选效果取决于高/低温的设定值、保持的时间、温度变化速率和循环的次数这四个方面。可以对温度进行调到需要的高度来观察温度的变化速率，这样的试验效果较好。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.

ESS-600-1000环境应力筛选系统在操作说明书对3C电子设备做温湿度试验中，如果设备中的元器件数量多，则循环次数应该相应的增加。在保证不会对产品造成损坏的情况下，可以适当地增强振动，这样测量的效果也很好。因此，也广泛应用于航空航天产品、高速列车、器械、资讯电子仪器仪表、高级复合材料、电工、 车辆、金属、汽车电子、各种电子元器件在高低温或湿热振动环境下对产品进行环境应力筛选试验。 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.
