How about a relatively non-technical arguement to chew on?
For years we have procured pwb's to the mil- or ipc-d 275 rules from
several very reputable suppliers.  All the boards are delivered with a 1
to  2 inch wide manufacturing panel surrounding the board, which is
routed off after we complete assembly.  In all cases, the shops have
regarded this panelized board as "the board" and have placed the test
coupons one-half inch from the"the board", as the spec requires.  We
have always concurred with this, as we didn't particularly want our
manufacturing panel cut up to remove coupons, and we understand that
this is pretty much industry practice, and also feel that having the
coupon one inch closer to the circuitry makes no real dif.   Now,
another faction of my company with a more purist attitude tells me none
of my boards are spec compliant because of coupon placement.  We have
already gone to the needless trouble and expense of modifying drawing
notes to allow this condition, so I'm not in a panic,  but I'd still
like the decision from the jury.

Thoughts?

Thanks

Ralph
