Kat,
I have this type of damage in some BGA. However, this shared artifact
take the cake. In PCB/PWB there is a 0.030 keep out zone from edhe of card
. No too sure how that applies here. The rough edge is a sure point for
MOISTURE INGRESS into the compromised laminate edge. Very curious on what
ruling you receive for supporting document. Let me guess that the supplier
is OVERSEAS.
Victor,
