How Environmental Stress Screening Reduces Potential Field Failures? Environmental Stress Screening (ESS) refers to a testing process involving subjecting a newly assembled or manufactured product, usually an electronic, to environmental stresses. This series of testing is important for the purpose of identifying and eliminating the latent defects of an electronic product that are usually introduced during the product manufacturing process.
 Environmental testing refers to the measurement of performance of equipment under specified environmental conditions such as large, swift variations in temperature, solar radiations, extremely high or low humidity, corrosive conditions, among others which I will focus on later in details.
 What is Thermal Shock Test?The adaptability of a product towards the rapid and extreme variation in temperature will need to undergo a test for its durability called the Thermal Shock Test.
Any kind of product or equipment could be exposed to contrasting weather conditions, either too hot or too cold.  Temperature and Humidity test chamber (which is also called environmental test chamber) is designed to evaluate the product’s quality and reliability against different environmental conditions, especially for temperature and humidity.
