MIL-HDBK-179A, MILITARY HANDBOOK: MICROCIRCUIT ACQUISITION HANDBOOK (20 JUL 1995) [S/S BY SD-18]., This handbook is intended for guidance, reference, and training for all parties involved in the selection of microcircuit devices for use in military applications. This includes those involved in the application, selection, and handling of microcircuit devices. The handbook will assist the government and associated contractors in identifying and communicating specific application requirements. The handbook is structured for use by the System Program Office (SPO), system integrator and device manufacturer. It is intended to be applied on a contract-by-contract basis. The maximum benefit of this handbook can be achieved if it is used early in contract development and allowed to impact system specifications, statements of work (SOWs), and system design considerations.
