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

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.

New ICC ANSI A117.1 2009 Edition on Accessible and Useable Buildings and Facilities has been approved

ANSI A117.1, the foremost standard on facility accessibility, has been issued as the new 2009 Edition.  First published in 1961, this standard is celebrating its 50th anniversary with this new release.  Titled ‘Accessible and Usable Buildings and Facilities’, A117.1 provides the guidelines for designers to create buildings that offer unobstructed entry and use for people with a multitude of physical challenges.

ANSI A117.1 is referenced by the International Building Code, as well as the model codes of the BOCA (Building Officials and Code Administrators) and the Southern Building Code Congress (SBCCI).  You’ll also find it in many federal documents and state accessibility laws.

The new 2009 Edition has been accepted but has not yet been released for public distribution.  Document Center Inc. will be shipping the new standard when it becomes available in November 2010.  Contact us at www.document-center.com, info@document-center.com, by phone at 650-591-7600 or by fax at 650-591-7617 to order your copy of this new release now.

New ASTM D3951 2010 Edition for Commercial Packaging released

ASTM D3951-98, Standard Practice for Commercial Packaging, has been revised with the release of the new 2010 Edition, ASTM D3951-10.  As you can see, this is the first revision of the standard in over 10 years.  It is one of Document Center’s most frequently ordered ASTM standards on packaging and is available now.

ASTM describes the standard as follows:  “(It)  covers the requirements for the commercial preservation, packaging, packing (exterior container), unitization, and marking for supplies and equipment. It provides for multiple handling and shipment by any mode, and storage periods of a minimum of one year in enclosed facilities without damage to the product. It also provides for package quantities suitable for redistribution without additional repackaging or marking. Planned storage that exceeds one year requires more than minimum requirements for physical and mechanical protection.”

You’ll want to know that this practice establishes minimum requirements for packaging of supplies and equipment as covered in Title 49 of the Code of Federal Regulations, with the exclusion of  ammunition, explosives, or hazardous materials.  It is also referenced for some Department of Defense shipments not covered by MIL-STD-2073/1.

Copies of this new ASTM D3951-10 may be purchased in paper or pdf format from Document Center Inc. at www.document-center.com, info@document-center.com, by phone at 650-591-7600 and by fax at 650-591-7617.

MIL-P-50884, one of the primary military printed wiring specs, is released with new Amendment 3

MIL-P-50884, Revision E, has a new Amendment 3 dated 9/1/2010.  The document, Printed Wiring Board, Flexible or Rigid-Flex, General Specification for, is a mainstay of the military specifications in this classification.  Inactive since 1999, the document is still available for use for replacement parts.  Compliance with the new changes is mandated by 12/1/2010.

Following the new protocol allowed by the creation of these documents in word processing programs, the amendment is interfiled within the body of the document.  While this makes using the document easier, it does present the reader with the challenge of identifying changes to the specification.  Unfortunately, there are no redline editions of the military documents available.  But this specification does at least have lines in the margins to identify areas with corrections.

MIL-PRF-31032 has been added to the referenced documents section.

In Appendix A, paragraph A.3.5.1.1 has also been modified, as has paragraph A.3.5.2.7.  There are also 5 new subclauses for A.3.5.4.  And tables A-IV and A-VI have been corrected as well.  Sections A.3.6.7.4, A3.7.4.6, A.3.7.4.8.2, A.3.7.5.1, A.4.5.2.1, A4.5.2.2, A.4.5.4.4, A.4.6.2 parts, A.4.8.1.8 and subsequent parts, A.4.8.2, A.4.8.4.1, A.4.8.4.6, A.4.8.4.9, A.4.8.6.2.1,  and A.7.3 have also been amended.  Sections A.7.18 and A.7.19 have been added.

Appendix B is untouched, but section C.6.3 has been corrected in Appendix C.  Appendix D adds the previous edition of this specification, MIL-P-50884 Revision E with Amendment 2, to the documents it replaces, understandably so.  And Appendix E has been completely deleted.

In Appendix G, Figure G-9 has been modified, as has Figure G-16.  In Appendix H, Table H-1 is also amended.  Sections H.4.3.4.1,  H.4.3.9, and Figure H-4 have corrections as well.

The new issue is 138 pages and is available from Document Center Inc. at www.document-center.com, or by email at info@document-center.com, phone at +650-591-7600 , or fax at +650-591-7617.

AAMI-ST79 – The new 2010 Edition is available for preorder now

The AAMI recommended practice ST79, Comprehensive guide to steam sterilization and sterility assurance in health care facilities, is now approved in a new 2010 Edition and public distribution is pending.

The standard consolidates 5 previous AAMI steam sterilization standards, the AAMI ST33, AAMI ST35, AAMI ST37, AAMI ST42 and AAMI ST46.  It was the first AAMI standard to be released in a binder edition, since the material covered is extensive.  The binder format facilitates easy access to the various topics, like lowering and limiting bioburden before sterilization, properly preparing items for sterilization, selecting the appropriate sterilization parameters, and establishing and implementing controls to maintain the sterility of sterilized items until they are used.

Users of this standard will find guidance to promote assurance of sterility and to guide health care personnel in the proper use of processing equipment.  The document includes functional and physical design criteria for a number of sterilization processing areas  including decontamination, preparation, sterilization, and sterile storage areas.  There are sections to assist with staff qualifications, education and other personnel considerations.  Also covered are  processing procedures,  installation, care and maintenance of steam sterilizers, quality control and, of course, quality process improvement.

The new ANSI/AAMI-ST79:2010 replaces the previous 2006 Edition with both Amendments 1 and 2, which is no longer available.  Because the new ANSI/AAMI-ST79 was only recently approved (9/3/2010), there will be a delay until the new edition is available.  Normal lag time can be from 1 to 3 months for the formatting and publishing functions to take place and the standard to become publicly available.

To purchase your copy of ANSI/AAMI-ST79, use our website at www.document-center.com, or call us at 650-591-7600, fax 650-591-7617, or email to info@document-center.com.

Your order can be placed now and shipped as soon as it is released.

IPC-A-610 New Revision E is a must-have for Electronic Assembly Quality
