摘　　要：高加速应力筛选(HASS)技术是一种新型的试验技术,试验效率高,能有效保障产品的可靠性。介绍了高加速应力筛选的基本原理和典型的HASS过程,然后将HASS应用于某航空电子产品,提出了一种基于常规试验设备的HASS方案。根据环境应力筛选(ESS)与基于强化试验设备的HASS技术,给出了基于常规试验设备的HASS初始剖面制定过程,并从理论上验证了该剖面的有效性,筛选验证结果表明该剖面具有安全性。Highly Accelerated Stress Screening （HASS） is an emerging reliability test technology. With high efficiency, HASS can effectively guarantee reliability of product. The fundamental principle and the typical process of HASS were introduced. A HASS scheme based on routine test equipment was proposed and applied to a certain avionics. According to the technologies of Environmental Stress Screening （ESS） and HASS based on enhancement test equipment, the HASS initial profile was designed, and the validity of the HASS initial profile was proved in theory. The validation result showed that the HASS initial profile is safe.
