Amendments issued for two top Military Microcircuit Specifications, MIL-PRF-19500P and MIL-PRF-38535J

Thursday, May 31st, 2012

Two of our all-time best selling military specifications for the semiconductor industry have just been modified with amendments:  MIL-PRF-19500, “Semiconductor Devices, General Specification for,” and MIL-PRF-38535, “Integrated Circuits (Microcircuits) Manufacturing, General Specification for.” The new editions are available from Document Center Inc. now.

The new 171-page MIL-PRF-19500P with Amendment 1 establishes the general performance requirements for semiconductor devices. Product assurance is provided by effective screening, conformance inspection, and process controls to mitigate risk. Mission assurance and standardization of parts are the highest priorities. This specification establishes a heritage program of semiconductor devices the military and space community can rely on to be dependable and available.

It contains the performance requirement and verification methods for semiconductor devices. The main body specifies the performance requirements and requires the manufacturer to verify that their devices are capable of meeting those performance requirements.

Appendix A contains definitions of terms used throughout the specification. Appendix B contains abbreviations and symbols. Appendix C contains the Quality Management (QM) Program. Appendix D contains the quality system. Appendix E contains the standard verification system for qualified products. Appendix F has been cancelled. Appendix G contains discrete semiconductor die/ship lot acceptance. Appendix H contains critical interface and materials for semiconductor devices.

The margins of MIL-PRF-19500P with Amendment 1 are marked with asterisks to indicate modifications generated by this amendment. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations.

MIL-PRF-38535J with Amendment 1 establishes the general performance requirements for integrated circuits or microcircuits and the quality and reliability assurance requirements, which are to be met for their acquisition. The intent of this 202-page specification is to allow the device manufacturer the flexibility to implement best commercial practices to the maximum extent possible while still providing product that meets military performance needs.

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 radiation hardness assurance (RHA). Appendix D is mandatory for statistical sampling, life test, and qualification procedures used with microcircuits.

Although the document states that marginal notations are not used to identify changes with respect to the previous issue due to the extent of the changes, there are actually a number of sections with marginal notations suggesting that these are the areas when the amendment has generated changes to the text.

MIL-PRF-19500 New Revision P on Semiconductor Devices Released 10/20/2010

Thursday, October 28th, 2010

MIL-PRF-19500 (formerly MIL-S-19500) titled Semiconductor Devices, General Specification for, has just been revised. This specification is one of the top Semiconductor specs for use by the Department of Defense.

The release of new 170 page Revision P requires compliance by April 20th, 2011.  Changes from the previous Revision N are extensive and are not noted in the margins, as is sometimes the case.

This specification covers the general requirements for semiconductor devices used in electronic equipment procured by the U.S. military.  The semiconductor devices covered by it are unique due to the fact that these devices must be able to operate satisfactorily in systems under demanding conditions such as: 20 g’s vibration, 100 g’s of shock, salt atmosphere, wide temperature range (e.g. -55°C to +150°C).  In addition, these requirements are verified under a qualification system.  Commercial components are not designed to withstand these environmental conditions.

MIL-PRF-19500P establishes the general performance requirements for semiconductor devices.  Detail requirements and characteristics are specified in the specification sheet.  Revisions to this specification and it’s corresponding specification sheets are structured to assure the interchangeability of devices of the same part type regardless of manufacturing date code or conformance inspection (CI) completion date.

Five quality levels for encapsulated devices are provided for in this specification, differentiated by the prefixes JAN, JANTX, JANTXV, JANJ, and JANS. Eight radiation hardness assurance (RHA) levels are provided for the JANTXV and JANS quality levels. These are designated by the letters M, D, P, L, R, F, G, and H following the quality level portion of the prefix. Two quality levels for unencapsulated devices are provided for in this specification, differentiated by the prefixes JANHC and JANKC.

The main body of this document specifies the performance requirements and requires the manufacturer to verify that their devices are capable of meeting those performance requirements.

Appendix A contains definitions of terms used throughout the specification.  Appendix B contains abbreviations and symbols.  Appendix C contains the Quality Management (QM) Program.  Appendix D contains the quality system.  Appendix E contains the standard verification system for qualified products.  Appendix F has been canceled.  Appendix G contains discrete semiconductor die/ship lot acceptance.  Appendix H contains critical interface and materials for semiconductor devices.

The document number was changed from MIL-S-19500 to MIL-PRF-19500 during the Mid-1990′s Mil Spec Reform to designate the performance specification status of the document.
