MIL-PRF-38534, “Hybrid Microcircuits, General Specification for,” has just been revised. The new Revision J is available from Document Center Inc. in paper format, for pdf download, and as part of our multi-user Standards Online subscription service. This document is one of the primary U.S. military publications for microcircuits and has been one of our best sellers on the topic for many years. If you use this spec, you’ll need to comply with the changes in Revision J by September 9, 2015.
MIL-PRF-38534J was formerly called out as MIL-H-38534. It was renumbered back in 1995 as a result of Mil Spec Reform. The new Revision J is a total of 151 pages. However, the main requirements account for the first 20 pages only. The balance of the publication is a series of Appendices (A through G – but not including B which was discarded a while back) which provide the details of implementing the specification. Since the previous Edition (Revision H) was only 139 pages, you can tell there have been some updates in this issue. Appendix G has been completely re-written. Other changes are marked with asterisks in the margins for your convenience. As is usual, the document does warn you that the marking of the areas with updates are done as a convenience only and may not be complete.
As many of you know, the U.S. military is an active and major consumer of electronics. This means that the contract requirements for microcircuits, components, and so on play an important role in the industry. This publication gives device manufacturers the baseline requirements for the performance of not only hybrid microcircuits but also multi-chip modules (MCM) and similar devices. You’ll use the document if you’d like to be (or want to continue to be) included as part of the QPL (Qualified Products List) program.
You’ll find information on 7 quality assurance classes (D, E, F, G, H, K and L) in MIL-PRF-38534. There is a separate clause with the requirements for each. There’s also a Table II with an implementation summary that you’ll find to be particularly helpful. Designation formats for these devices is covered in depth, as is certification and marking.
Of course, the Appendices take up the bulk of the specification. Here you’ll find guidance on your quality management program, generic performance requirements, generic design and construction criteria, and so on. The interactive index at the end of the publication is still part of the document.
