Definition:  A grouping of two or more individual microcircuits mounted on a common mounting or on each other. Each microcircuit must be separable and capable of functioning in accordance with its given name. The item is generally part of an electrical/electronic subassembly and cannot be assigned a more specific item name. It excludes items containing electrical/electronic components other than microcircuits, except that when mounted on a printed wiring board it may include a connector(s). For items containing other components in additition to MICROCIRCUITS see CIRCUIT CARD ASSEMBLY and ELECTRONIC COMPONENTS ASSEMBLY. For items having a complete individual electrical/electronic function, use the applicable item name such as AMPLIFIER (as modified), OSCILLATOR (as modified) or POWER SUPPLY.

Basic Name:  MICROCIRCUIT

Description:  1. 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 substrate to perform an electronic circuit function. The elements may be formed on or within a semiconductor material substrate, 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. Excludes: CIRCUIT CARD ASSEMBLY; ELECTRONIC COMPONENTS ASSEMBLY; and PRINTED CIRCUIT BOARD.
