Enclosures are the high-precision, close-tolerance housings which encase electronics products and assemblies. Typically constructed from various metals and plastics, enclosures are an integral part of electronics products and are critical for protection, environmental control, interconnection, compactness and multi-unit integration.

Environmental Stress Screening is a process for the detection of early life defects in which components or assemblies are tested at the temperature and voltage extremes of their normal operating conditions for extended periods.
