The VP is cleaner than other soldering processes, so we have less problems with VP. We let the boards pass a tunnel cleaner (degreaser,solvent,water)and then spray coat with Humiseal. Simply all. No specials. /Inge -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Jowan Iven Sent: tisdag 30 juni 2009 09:33 To: [log in to unmask] Subject: [TN] Conformal Coating and vapour Phase Hi all, Does anyone have some knowledge about putting conformal coating on a board that has gone through a vapour phase process? Are there any known issues? Or are there some process considerations regarding cleaning prior to conformal coating?
