The Microcircuit Application Handbook, MIL-HDBK-179 (ER), dated 25 October
1993 is becoming the Army guide for the determination of suitability of
a microcircuit packaging approach and the selection criteria for microcircuit
suppliers and part types. This document is based on recommendations
provided by the DoD Defense Science Board. A Multiple Entry Matrix
lists all possible DoD equipment environments, which ranges from temperature
humidity controlled to space. Parts for these application environments
include commercial and industrial grade plastic encapsulated microcircuits
(PEMs), industrial qualification of PEM approaches, and QML. By implementation
of the Microelectronic Selection Criteria Spreadsheet, the equipment developer
provides the rational for selection of the PEM supplier and the part selected.
The data required is mainly available through the supplier and should determine
if he is implementing Best Commercial Practices (BCP). This data
will assure the parts surpass the equipment quality and reliability requirements.
This approach to the use of non-military approved microcircuits is already
being implemented on several Army Programs which will be discussed.
The vision is to make the handbook a requirement for all equipment developed
at the US Army Communications-Electronics Command (CECOM).
