PRODUCT DESCRIPTION
Rosin based flux corresponding to J-STD-004B type ROL0. Stannol 500-6B UV 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 UV 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.
The Stannol soldering flux 500-6B UV contains a small amount of UV tracer to make the residues visible after soldering
using UV light.
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 for wave soldering should be between 245-270°C. The temperature for selective
soldering should be between 260-310°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.
