DESCRIPTION
Rosin based flux corresponding to DIN EN 29454-1 type 1.1.3, EN 61190-1-1 type ROL0 and J-STD-004 type ROL0. Stannol
500-6B is a ready-to-use flux for single-, double-wave and selective soldering processes. It can also be used for manual
soldering as it leaves very safe residues either by use in a dipping process or in a Stannol Flux-Pen.
Stannol 500-6B possesses very good wetting properties on all available lead-free and lead containing solders and permits
handling immediately after soldering because of its special resin composition. The halide-free resin residues have a high
surface insulation value. A subsequent cleaning operation can therefore be eliminated. The hard residues provide improved
adhesion properties for the application of conformal coatings of either silicone or polyurethane. Even connectors of brass or
bronze, which normally require the use of halide-activated fluxes, can be successfully soldered with the Stannol 500-6B flux.
APPLICATION
In principle, all application methods are feasible, although when foaming is employed some modification of the fluxer may
be needed. The preheating should be set in such a way that the temperature on the top side of the printed circuit board
reaches 90°-110°C. The solder temperature should be between 245°-260°C.
Evaporation of solvent can change the composition. Evaporation causes an increase of the solid content and therefore the
density increases. This can be checked with the Stannol Mini-Titration-Kit.
