Highly Accelerated Life Test(HALT)And Highly Accelerated Stress Screen(HASS)

In this paper,the producing,development and application of the HALT/HASS technique are briefly introduced.Based on the deeply analyzing the fundamental principle of the HALT/HASS technique and the relations between the applied environmental stresses and the failure modes excited by these stresses,the method that is used to design the HALT/HASS profile is described.Moreover,the HALT/HASS characteristics are particularly explained,and the needing resource in HALT/HASS and other matters are presented in detail.
