Displacement Damage is the result of nuclear interactions, typically scattering, which cause lattice defects. Displacement damage degrades minority carrier lifetime; a typical effect would be the degradation of gain and leakage current in bipolar transistors.

TID effects imply that one incident irradiation causes the ionizing of matter and it appears charge in places where it should not. TNID effects are motivated by the displacement of the atoms of the crystalline lattice from their balance sites.

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.

Performing an environmental test means subjecting the device or system to certain environmental conditions (cold, dry heat, relative humidity, etc.) in order to check if the operational parameters remain within the range defined by the applicable regulations.

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.
