REQUIREMENTS
3.
Preproduction - This specification makes provision
3.1
for preproduction testing.
Parts and Materials - In the selection of parts and
3.2
materials~ fulfillment of major design objectives shall be the prime
In so doing the following shall govern:
consideration.
(1) Microelectronic technology shall be considered and
microelectronic items shall conform to the require-
ments specified herein.
(2) Other parts and materials requirements shall
conform to MIL-E-5400.
(3) Non-repairable subassemblies, as outlined in
MIL-E-5400, shall be used when practicable.
The general size of the subassembly and the
amount of circuitry to be included therein
shall be approved by the procuring activity.
Non-repairable subassemblies must be reliable
(See 6.4).
(4) When previously produced models of this equipment
did not use non-repairable subassemblies, the
design shall not be changed to employ non-repairable
subassemblies without the approval of the procuring
activity.
Nonstandard Parts and Materials Approval - Approval
3.2.1
for the use of non-standard parts and materials (including electron
tubes, transistors, and diodes) other than micro-electronic devices
shall be obtained as outlined in MIL-E-5400. Microelectronic devices
shall be approved as outlined in AR-5.
Microelectronic Module Assemblies - When used, micro-
3.2.2
electronic modular assemblies shall meet the requirements of AR-5.
Modules, Maintenance - The electronic portions of the
3.2.3
equipment shall be divided into maintenance modules. Maintenance
modules shall normally be considered repairable.
