5962 Microcircuits, Electronic
Note-(1) A microcircuit is defined as
follows: A small circuit having a high
equivalent circuit element density, which
is considered as a single part composed
of
interconnected
elements
placed
and/or formed on or within a single sub-
strate to perform an electronic circuit
function. The elements may be formed on
or within a semiconductor material sub-
strate; may consist of conductive film(s)
formed on an insulating substrate; or may
be a combination of one or both of these
types with discrete elements. (2) The
term
microcircuit
, as applied to circuit
devices included in this class, is delimited
to exclude items consisting solely of inter-
connected
microcomponents
(discrete
miniaturized components). Also excluded
are items fabricated in the form of mono-
lithic thick-film or thin-film structures that
in themselves are not functional elec-
tronic circuits (e.g., Capacitors, Resis-
tors, Transistors, or
arrays
thereof).

grated Circuit Modules, Integrated Elec-
tronic Devices: Hybrid, Magnetic, Mo-

Networks.
5963 Electronic Modules
Note-The term
electronic module
as
used in this class designates an elec-
tronic component designed for use in
various equipment or end item applica-
tions, and capable of controlling voltage
and/or current to produce gain, oscilla-
tion, switching, or similar integral elec-
tronic functions. It consists of a collection
of miniaturized electronic parts and/or el-
ements in a single replaceable package
with plug-in mounting which will also
complete the required electrical connec-
tions. It is not normally subject to disas-
sembly as distinguished from such items
as CIRCUIT CARD ASSEMBLY and
ELECTRONIC COMPONENTS ASSEM-
BLY. These modules conform to industry
or government specifications/standards
that define all physical dimensions and
electrical parameters required to promote
commonality and ensure proper opera-
tional performance.
