Hi William
Yes, I have seen several occassions where "dry weave" of laminate - both core
and prepreg - have resulted in severe wicking and/or voiding that shows up as
blow holes in solder joints.

Also microsectioning techniques "can" cause gouging of glass

BUT  if dry weave is present and the microsections are examined in the as
polished condition, the presence of plating down along the bundles is pretty
obvious.
