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.

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!!
