Electronic Rosin-Based Fluxes

Amerway 100 Non-Activated (R) -- The Amerway 100 Type "R" is a pure water white rosin flux in an alcohol solvent system meeting the requirements of J-STD-004, flux type LO, designated as a liquid based soldering flux.  This flux contains no activators or halide making this the least corrosive type of rosin flux available.

Application:  Amerway 100 Type "R" can be used for critical electronic assemblies where current leakage is extremely sensitive and where flux removal is not necessary.  The Amerway 100 Type "R" flux can be applied by wave, foam, spray and dip application.  The Amerway Type "R"  can be used on the following metal provided the surfaces are not heavily oxidized.  

     Cadmium Plate:          Tin dipping

     Copper:                     Tin Plate electrolytic

     Gold:                          Tin/Zinc plate

     Silver:                        Solder dipped

Benefits:  

• Amerway 100 Type "R" is formulated with a high quality grade of water white rosin which meets the test requirements for flux activity classification LO Type for Joint Industry Standard J-STD-004

Residue Considerations:  The Amerway 100 Type "R" flux residues are non-conductive and non-hygroscopic and are not considered to be corrosive.  While it is recommended that flux residue be removed from the assembly after soldering, no corrosion or current leakage will occur if residue remains.

Residue Removal:  For effective removal of flux residue, the Amerway 900 Enviro-Clean-25 can be used in an aqueous cleaning system.

Flux Control:  During use of the flux most fluxes tend to increase in viscosity and thicken because of solvent evaporation.  For best results, it is recommended that the evaporation losses be replaced by the addition of Amerway 105 Thinner until the proper specific gravity is achieved.  The specific gravity can be determined by using a hydrometer, taking into consideration the temperature effect.
