Yes, scratches on the bond enhancement material on the copper surface of
the inner core. This is addressed by IPC-6012C paragraph 3.3.2.9, which
allows up to 10% of the conductor area.

Subject: Discoloration under the soldermask
Steve, would you be so kind to put them up on your site?....the
discoloration is underneath the soldermask. do any of you guys/gals know
what may cause this to happen?. this is across multiple date codes. I am
looking for a possible root cause so that I can decide whether or not to
reject these boards and issue a corrective action to the vendor.
Thanks!
Amol
