Our assembly vendor is telling us they found a number of defects on a small shipment of fabs.  Some of these are a bit odd looking, some are obvious.  BUT, two of the pictures show obvious mechanical damage.

A little background:  boards were quick turn, from a vendor we have used for 20 years with extremely good results.  Shipped to Hong Kong, where the vendor couldn't locate them for over 2 weeks.  Now they found them, said the vacuum bags were compromised, moisture indicators were pink.

We just need about 35 of these built for internal testing, we don't need long term field reliability.  Any ideas what this might be, and would you use them for engineering purposes?

BTW, this is clear soldermask, outer layers are copper planes.

Thanks,

Pete
