                Hi Prasad:
                One possible solution is to create an in house document
(ABCXYZ) that list all the applicable documents whether internal or
external. The PWAs or any part drawing will mention this created
document and it will have a flow down to the correct drawings ( i.e.
assemble per ABCXYZ).
        Regards,
        Ramon

My opinions

1) I agree with your assessment that J-STD-001 does not reference
IPC-7711/7721, in the Rework and Repair section or in the Applicable
Documents, so "no", I do not think you have misinterpreted.

2) Rework procedures are the responsibility of the manufacturer.  As
long as they are documented, and the workmanship meets all J-STD-001
requirements, you are covered.  Repair procedures must be agreed upon by
the manufacturer and the user.  Again, they must be documented.  The IPC
7711/7721 are useful to reference for these procedures.  If you would
like them to apply as a REQUIREMENT, then listing on the drawing is not
a bad idea.

3) As long as the assy meets all workmanship requirements of J-STD-001,
and the procedures are documented (IPC-77## or otherwise) then you will
not be in violation of J-STD-001 compliance.

Subject: [TN] relationship between J-STD-001 and IPC 7711/7721: need
your help.

In a nutshell here is where i need some help:

we call out and enforce J-STD-001, Class 3 on our assembly drawings.
Very often we do repair/rework on these assemblies and we do not seem to
have a clear link between IPC 7711 and IPC 7721 wherein the how-to's and
what to control are listed and J-STD-001, Class3. The only words that
address repair/rework in
J-STD-001 have to do with the acceptance criteria for such operations.

Ques:

1. I am reading this correctly?
2. How do i ensure that the repair and rework procedures and the skill
sets are adequate? do I need to explicitly state in on the drawing the
need for repair and rework per IPC 771 and IPC 7721?

3. If i do not state that then is the compliance to
J-std-001 violated?

Thanks

Prasad Godavarti
