Best to establish what type of residue is causing this problem and then stamp it out.Speak with SCOPE Labs who offer PCB extraction followed by IR and IC work. So many problems with porous resist at present and NON ionic materials that you really nee

Kev, You seem to have a very good knowledge of your process and can convey it clearly and precisely. My advise to you is to dis-regard the BS most of these guys churn out and follow your own gut. They will ask a s**t load of irrelevant Q's in some fu
