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.
Sample requirements In order to make your test data more realistic and effective,The test chamber must be used reasonably while meeting the following principles: The total mass of the load is not more than 80Kg per cubic meter of studio volumeThe total volume of the load cannot be greater than 1/5 of the working chamber volume On any section perpendicular to the dominant wind direction,The sum of the load areas should be no more than 1/3 of the cross-sectional area of the working chamber.Do not block the flow of airflow when the load is placed.
