Earl: The current OSP coatings are not based on any type of flux chemistry
such as the old Sealbrite. That was a rosin based product from London
Chemical Co.
The OSP forms an organo-metallic complex on the surface of the copper to
protect it. It does not aid or contribute to the fluxing operation. The
coating is actually broken down by the flux allowing you to solder to non
oxidized copper.

Jana,
I appreciate you are not into fluxes and the answer concerning OSP
composition. I'm sure the OSP chemistry is compatible - no kidding - with
current flux chemistries or how could it work
When we used "SealBrite" it was essentiall a flux. Does someone out there
know the answer to my question concerning flux composition in terms of
Jana's answer?
Earl
