When to Update the Minor Rev of a Part Number
E-8: Parts and Part Numbers
The information in this section is extracted from PROC CHNGING PART REVS,
Rev B (115067-A). (See Appendix F for this document’s location.)
Programmed Parts
For single-product reporting, a minor revision change is required if the description
changes, or the raw device changes for functional reasons but stays in the
same
physical package, or for program or speed changes.
For multiple-product reporting, a minor revision if all products phase-in at the
same time
PCB Assemblies
A minor revision is required for the following types of changes. (For
multiple-product reporting, this applies if all products will phase-in any of the
changes at the same time.)
• Functional H/W changes (electrical or mechanical) that are backward
compatible.
• Bug fixes.
• Major component rev changes that need traceability.
• Description changes.
• Non-functional drawing adjustments and corrections. Assemblies never built
incorrectly due to drawing error.
• Minor component rev change on assembly that doesn’t need traceability, for
example, a change in AVL.
• BOM corrections such as quantity errors and reference designator corrections.
Assemblies never built incorrectly due to this BOM error.
• Changes to flash devices (in-circuit programmables).
• Labels, sockets, general hardware mechanics.
• BOM structure changes.
• Additions or revisions of reference documents on an BOM.
• A/W (artwork) spin, such as bury wires, that does not produce any BOM
changes or removal or addition of component footprints.
