RSF-R39 Rosin No Clean Flux is a mildly-activated rosin ux that is considerably more active than water-white rosin. Recommended for electrical and electronic soldering applications - excellent for P.C.B repair and rework Can be safely left on the circuit board after reow without cleaning. No refrigeration necessary. "Made in USA"

Application

The active ingredients in RSF-R39 are non-ionic and non-conductive even in the presence of moisture. Like rosin, it becomes active only at elevated temperatures, reverting to an inactive state at room temperature. It is recommended for all applications where post-soldering cleaning is not feasible, and the residue must be highly insulating.
