I just the middleman for the sales of this PCB, now I am in dilemma
whether to reject this Analysis to the Supplier or claim it back to
Customer.
From what I see, this paint should happened before the components is being
mounted since there isn't any trace of paint on those components surface.
But who did it? haha

Yes, it a multi-layer board but the delamination area have not pose an
issue so far.
