Thirty-some odd years ago when I was a novice designer, I was trained that
the revision level of a PCB assembly (PCBA) must match, or be greater than,
the revision level of the bare PCB fab.

We have a situation now with usable Rev 5 bare board glass that is being
populated for a different application, requiring a new part number for the
PCBA and the BOM.

I'm inclined to do the initial release of the new PCBA and BOM at Rev 5,
based on experience.  My boss wants a Rev 0 release.

I can't remember what document originally specified the form, fit and
function rules for PCB and PCBA revision level control.

Can someone provide hard copy evidence for revision level control to
substantiate, or disprove, what I was taught back in the day?

Thanks and Best Regards,
