Yes.
RA -- rosin active/activated
The rosin itself is not a problem but the activators may leave significant
amounts of halides, chlorides, etc.
HCl is a common addition that makes a flux aggressive but then requires
cleaning (CFCs work well).

Subject: [TN] Corrosion


Has anyone heard of rosin based fluxes causing corrosion?

It is on a connector with solder cup connections and the flux used is
a RA flux.  The pins and the solder is showing signs of corrosion.
Could this be caused or accelerated by the flux?

Any help is appreciated.
