We have a 12 layer board with a heavy ground layer that had
three edge BNC type connectors installed using a mini wave.
The circuitry tracing away from the connectors is surrounded by
vias. There is a distinct lightening of the board material I
have typically associated with measling. This lightening
however, doesn't have any fiber crosshatching I am used to
seeing with measling, not does it look like classic
delamination. I have documented the event as delamination for
lack of a better description.
The opposing consensus is that it is "merely" soldermask
discoloration. Without classic delamination or measling
features, I don't feel I have a leg to stand on to call it
anything other than that. (Don't worry though - both sides feel
the Customer needs to review the board no matter WHAT the defect
is).
Does anyone have any opinions?
