MIL-PRF-38534 for hybrid microcircuits has been revised. The new Revision K is available from Document Center Inc. now. It’s titled Hybrid Microcircuits, General Specification for. The performance specification replaced the obsolete MIL-STD-1772 back in 1996. It’s used for meeting the requirements for hybrid microcircuits used in government procurement. If you use this specification, you’ll need to meet the new updates by May 15, 2018.
The 175-page MIL-PRF-38534 Revision K covers hybrid microcircuits, multi-chip modules (MCM) and similar devices. Verification requirements are provided so that the manufacturer can meet applicable performance requirements for U.S. military use. Appendix A authorizes the use of 1 of 2 listed quality programs to verify compliance. Also included are the requirements for QML listing (Qualified Manufacturers List). FYI: The QML information is now maintained in a database by the Department of Defense.
This is an overview document, with detailed specification requirements provided by SMDs (Standard Microcircuit Drawings) and other specifications. In order to have your products authorized for procurement and for inclusion in products sold to the military, these general requirements must be met. So Appendix C defines generic performance verifications, Appendix D is on generic performance requirements for non-hermetic device technologies, and so on.
For those of you using the publication, you’ll want to know where the changes in the specification are. Instead of the usual black lines, asterisks are provided in the margins notating where the changes have been made. As usual, the document notes that these have been provided as a convenience only. This means that if there are changes that were not marked, you’ll still be liable if you don’t meet the update.
Of course, you’re going to need this new update, since there are many changes throughout the specification. Use Document Center Inc. for your purchase.
