MIL-PRF-38535


MIL-PRF-38535 is a United States military specification that establishes the general performance and verification requirements of single die integrated circuit device type electronics. It is a performance-based specification document defining the general requirements, as well as the quality assurance and reliability requirements, for the manufacture of microelectronic or integrated circuits used in military applications and high-reliability microcircuit application programs.

Origins and Evolution

The specification provides the device manufacturer with the flexibility to implement best commercial practices while still providing a product that meets military performance needs. To be granted such privilege, a manufacturer must be certified pursuant to the Qualified Products List and the Qualified Manufacturer List programs. Developed in 1995 pursuant to DoD 4120.24M, the QPL/QML program moved defense procurement processes away from the use of strict detail specifications to a newer system based on industry practices.

Specification Overview

MIL-PRF-38535 allows the device manufacturer the flexibility to implement best commercial practices while still providing a product that meets military performance needs.
As a performance specification, the document provides the device manufacturers with an acceptable established baseline to support Government microcircuit application and logistic programs. The basic section of this specification has been structured as a performance specification, which is supplemented with detailed appendices. These appendices provide guidance to manufacturers on demonstrated successful approaches to meeting military performance needs. These appendices are included as a benchmark and are intended to impose performance requirements. For QML microcircuits the manufacturer developed a program plan that meets the performance detailed in these appendices. Appendix A is mandatory for manufacturers of device types supplied in compliance with MIL-STD-883 and forms the basis for QML classes Q and V. Appendix B is intended for space application and is required for V level devices. Appendix C is mandatory for devices requiring RHA. Appendix D is mandatory for statistical sampling, life test, and qualification procedures used with microcircuits.
