Hello Leland, I can only agree here. Some time ago we had some PCAs that used a no-clean flux. They had some re-work using regular cleanable flux. Cleaning the PCAs resulted in the no-clean flux producing a milky residue that required further cleaning with a different solution. regards, Phil Dutton C.I.D. -----Original Message----- From: David Douthit [mailto:[log in to unmask]] Sent: Thursday, 9 May 2002 09:28 To: [log in to unmask] Subject: Re: [TN] Cleaning of No-clean Assemblies Leland, I hate to state the obvious but why are you going to use a "no-clean" flux if you are going to "clean" the PCA. Removing "no-clean" residues is problematic at best. To repeat the other posting use a clean able flux! It's much cheaper!! David A.
