I think this is a no-brainer, but here goes...  We were delivered boards in
panel form from one of our suppliers.  At Incoming Inspection, the panel was
rejected for excessive bow (>75% for SMT) and returned the supplier.  The
supplier called me and said that even though the panel exceeded the bow
requirement, the individual boards were acceptable.  When I quoted the bow
and twist requirement from IPC-6012, "Panels which contain multiple printed
boards which are assembled on the panel and later separated shall be
assessed in panel form." , he said yes, you measure the individual boards in
the panel.  I need clarification.
Thanks,
