MIL-STD-883E(4)
MICROCIRCUITS
This standard establishes uniform
methods, controls, and procedures for testing microelectronic
devices suitable for use within Military and Aerospace electronic
systems including basic environmental tests to determine
resistance to deleterious effects of natural elements and
conditions surrounding military and space operations; mechanical
and electrical tests workmanship and training procedures; and such
other controls and constraints as have been deemed necessary to
ensure a uniform level of quality and reliability suitable to the
intended applications of those devices. For the purpose of this
standard, the term “devices”includes such items as monolithic,
multi chip, film and hybrid microcircuits, microcircuit arrays,
and the elements from which the circuits and arrays are formed.
This standard is intended to apply only to microelectronic
devices. Document Date - December
