This is one area where I disagree with the IPC approach. IPC 7711 and
IPC 7721 should have never been put together. There was an expectation
that things that were done in 7711 would meet acceptance criteria
established in J-STD-001 and 610 for class 3. 7721 reflects
methodologies that exist, but are not necessarily compliant with
anything, unless you say so in your own documentation.

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
