In the Aerospace arena, with all the Configuration Management
Requirements on the Engineering side versus the mantra of outsourcing
from the Integrated Supply chain, who can't even spell requirement; do
yourself a favor and demand they be the same revision. Anyone who thinks
they can manage their data bases with all the new need to know
information about parts ( Lead-Free, ESD, Thermal, RoHS, Moisture )in
the BOM without maintaining the configuration and revision regimen,
deserves their own special place in Configuration Hell.
P.S. I've already checked with the few people in Hell,AZ to make sure
they weren't offended by that comment.

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.
