A cleanroom is a controlled environment where products are processed. It is a room in which the concentration of airborne particles is controlled to specified limits. Eliminating sub-micron airborne contamination is really a process of control. These contaminants are generated by people, processes, facilities, and equipment. They must be continually removed from the air.

Humidity may affect the life expectancy of a component by creating stresses on the part materials and altering its electrical properties in a way that the component reliability is significantly diminished. Temperature Humidity Test is those performed with the aim of evaluating the properties of materials used in components and the reliability of non-hermetic packaged devices in humid environments.

The Importance of Screening in Electronic Components

Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures. Using stress testing, defects are weeded out in a product where the root causes cannot be eliminated. Removing all the defective parts (infant mortality) brings the lot to the constant failure rate (working life) phase. The screening does not increase the reliability of the components but removes those showing weakness or defects. Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures.
