Microelectronic Interchangeability Demonstration - Interchangeability of
microelectronic elements shall be demonstrated as follows:
(1) For the interchangeability at the MIC level, it shall be demonstrated
for each type of functional MIC from one source, as used in the
system, that it is mechanically and electrically interchangeable with
that from another source. (see 6. 12).
(2) For the interchangeability at the maintenance module level, it shall
be demonstrated that modules typical of those to be used in the sys-
tem composed of MICS from one source are mechanically and elec-
trically interchangeable with modules composed of MICS from
(3) For the completed equipment, it shall be demonstrated that modules
composed of MICS from one source are interchangeable with corres-
pending modules composed of MICS from another source. When
interchange has been effected, no degradation shall take place in
system and subsystem performance.
