Leaded Chemistry RMA & RA Solder Flux

Leaded Chemistry RMA & RA Solder Flux Description:

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.
