I have a question about how document sets are structured, in particular
comparing the 6010 series with others like 2220 or 2610 series.

IPC-2222 specifically incorporates all of the generic IPC-2221 with this
statement:

1.1 Purpose The requirements contained herein are intended to establish
specific design details that shall be used in
conjunction with IPC-2221

IPC-2614 (for example) incorporates everything in the generic IPC-2611

3 REQUIREMENTS The requirements of IPC-2611 are a mandatory part of this
standard.

What this says to me is that the documentation only needs to call out the
specific standard to get the requirements of BOTH the specific and the
genericl standards.

Logically I assume that the same holds true for IPC-6011 and IPC-6012, but
in my latest copy of 6012C (PROPOSED STANDARD FOR BALLOT – JANUARY 2010) I
don't see any wording like this. Am I losing my mind? Do I have to call out
BOTH of them on my fabrication drawing?

onward thru the fog,
Jack
