Soldering Fluxes

Qualitek has a wide variety of soldering fluxes available for lead and lead free processes.

Flux Packaging Options
Flux is availabe in 1 gallon, or 5 gallon jugs
and 55 gallon drums.

No-Clean Fluxes
Qualitek no-clean fluxes are formulated to meet the changing requirements for today's soldering operations. Designed for wave soldering conventional and SMT circuit board assemblies, these extremely low solids content fluxes leave practically no residue after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical test probes and the expense of cleaning is eliminated. Qualitek NC fluxes are formulated to provide good activity while being halogen-free, non-corrosive and without surface insulation resistance degradation. No offensive odors are given off during soldering.

Water-Soluble Fluxes
Organic fluxes are commonly called "water soluble fluxes." Organic fluxes generally provide greater fluxing ability than rosin, but the ionizable nature of the water-soluble residue makes organic fluxes too conductive and potentially corrosive to leave on electronic assemblies. The organic fluxes are not as head stable as rosin fluxes but do provide more rapid fluxing action for high speed soldering. Because of the ability to remove organic flux residue with water and the ease of disposal of the cleaning solutions, organic fluxes are more frequently being used for electronics soldering applications. A circuit board assembly must be designed for the use of organic flux and water cleaning since all of the residue must be removed.

Rosin Fluxes
Qualitek rosin fluxes are formulated with high quality purified Grade WW rosin conforming to LLL-R-626 in specially blended solvent systems. The choice of the proper flux formula is based on the soldering application, desired rosin percentage, type of solvent and the activity level required.

Rosin Mildly Activated (RMA) Fluxes
Qualitek RMA type fluxes have high thermal stability for soldering multi-layer assemblies. Exposure to high preheat temperatures does not degrade solubility of the residue in normal cleaning solvents.

Fully Activated Rosin Fluxes
These fluxes are clear, homogeneous solutions of Grade WW rosin in special alcohol solvent systems into which have been incorporated highly efficient activating agents. The flux residues are non-corrosive and non-conductive when subjected to normal conditions where the solvent is volatilized and the residue is dry.
