This question goes out to all those with No-Clean Chemistry Experience -- Especially
those who manufacture No-Clean Paste, Flux, and Cored Wire.

Once a circuit card assembly has been assembled and soldered with No-Clean
products .... Assuming (I know I know...) that the fluxes have been fully activated,
what type of results should I expect to see....Assuming....that the boards and components were
"clean" prior to assembly.

More specifically, will Alcohol "reactivate" the no-clean flux or "free" contaminants that will
register on the Omega Tester?

-Carrie

P.S.  And No smart remarks like "How clean is clean" and "You know what happens when you assume".
