Environmental Stress Screening
ESS
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.
