I worked for 5 years at a contract mfr for the MIL-AERO markets.
This is a configuration conrol issue. It is always NICE to have all the
documentation match revs, but not a requirement. All of the scenarios you
listed below are valid examples of why all pieces of documentation would not
be the same revision level. Any manufacturer you utilize (and your internal
system) need to have some system in place to manage configuration control,
which includes all the related items and their revisions. What is required
is that you specify which is the controlling revision, which will be the
basis for the config control, identification, Pos, etc.
Hope that helps.

Subject: [TN] Assembly Documentation Question
The company I work for is going thru some documentation change discussions.
Below are the documents that are revisable. (The parts list contains all the
IC's, cap, res. etc. and documents.) The feedback I'm getting is the the
parts list and the assembly drawing should ALWAYS be the same revision
(becasue thats the way its always been).
Everywhere I've every worked, these are independent documents.
Here are my scenerio case: (All documentation released at Rev. A)
Scenerio (Rev: B): A part number change, of a 1K, 5% resistor to a 1K, 1%
resistor.
In this case, the part list and schematic would change, but it has no effect
on the assembly (because no part number or value is on the assembly
drawing).
PL1234567-1 Rev: B Parts List
AW1234567 Rev: A Assy Dwg
DS1234567 Rev: A Drill Dwg
PC1234567 Rev: A Artwork
PA1234567 Rev: B Schematic
Scenerio (Rev: C): The length of the screw holding the stiffener bar is
changed from 3/8 in. to 1/2 in.
The change is to the parts list only, the assembly drawing stays the same.
(no 3D view or side view)
PL1234567-1 Rev: C Parts List
AW1234567 Rev: A Assy Dwg
DS1234567 Rev: A Drill Dwg
PC1234567 Rev: A Artwork
PA1234567 Rev: B Schematic
The current discussion and question is;
-Can the parts list be independently revisible, from the assembly drawing?
-What do most of the assembly houses usually like?
Thanks for any response to this question.
