Solder flux RSF-R39-2

Applicator: Jar Formulation: Rosin (CAS 8050-09-7), proprietary ingredients Use: Precision electrical soldering Notes: Precision soldering of electrical connections for non-clean applications. Use Soldering Flux, TYPE RSF-R80 for general soldering. KEY FEATURES: RSF-R39 Rosin No Clean Flux is a mildly-activated rosin flux that is considerably more active than water-white rosin Recommended for electrical and electronic soldering applications Excellent for P.C.B repair and rework No refrigeration necessary Can be safely left on the circuit board after reflow without cleaning BRIEF SPECS: Appearance: Smooth and tacky amber paste Viscosity (Malcom): Typically 200 – 280 at 5 rpm @ 25 C Tack strength (per IPC J-STD-004): Initial TBD 6 hr @ 50%RH TBD 24 hr @ 50%RH TBD Fineness of Grind 1011) Pass, 8.9X109, Ohms at 96 hours 2.2X1010 at 500 hours Pass/Fail = final > initial/10) Shelf life of unopened containers is nominally 12 months. If the material has been chilled, the container should be allowed to reach room Nonflammable, noncorrosive.
