Environmental Stress Screening (ESS) is the process of exposing a newly manufactured product to environmental stresses in order to identify and eliminate latent defects introduced during the
Typical Stress LevelsScreening StrengthHalt / HassComponent Level ScreeningTo quantify and refine the above starting point guidance, "screening strength" models have been developed to assess the impact of varying stress levels, screening durations and defect detection approaches. These models were developed by the Air Force (RADC-TR-86-149, Environmental Stress Screening) and are implemented in the Quanterion Automated Re...See more on quanterion Delserro Engineering Solutions

Environmental stress screening (ESS) is also known as Burn-in, AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), or HASS (Highly Accelerated Stress Screening). Whatever the name, the idea is the same: create a test program that allows you to eliminate the infant mortality of your product.
3.1.5 Stress screening is a closed-loop process and relies upon information from monitoring to improve processes and screens; that is, it is an iterative process. Only through this can ESS be effective in terms of latent defect removal, and hence be cost effective.
5.4.1 Highly Accelerated Stress Screening (HASS) differs from HALT in that it is applied during the Production stage to precipitate and detect relevant defects. The same testing equipment is used as HALT but the testing is not as rigorous and is initially applied to 100% of items off the production line.
7.6.2 At unit and equipment level the application of thermal stress may not be possible in those cases where the thermal mass of the test item is large and the required rates of change temperature (>6o/min) cannot be achieved. In such cases it is important to apply vibration stressing with functional monitoring as the stress screening test.
