LIYI Ramp Rate ESS Test Chamber Environmental Stress Screening Chamber
During the ESS Stress Screening Test ,the product are subjected to precisely stressed so that defects in electric components and PCBs can be detected before leaving the manufacturer's plant. Detecting the weak points considerablely improve the robustness of the product because unreliable products are filtered out before they reach the customers and end users.
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.
