Starr, regardless of specs. why would you accepet any de-wetting that compromises attachment? Without guessing at possible causes of the problem, why don't you just re-work the parts in question? If you have no recourse through your supplier, contact an experienced service bureau such as; Solder Station One (714) 558-1019.
