Solder Flux Cleaning Solvent

Solvent based cleaning agents matched up to rosin based flux compositions and as such were the dominate cleaning technology used to clean printed circuit boards.

Solder flux cleaning solvent.

This wave solder flux is free of any halides halogens resin or rosin and is ideal for soldering high quality pcbs in pth smt and mixed technology. Need recommendation on solvent to remove solder flux i am assembling a fairly delicate tiny steel part by soldering it together i use stay brite a tin based solder that melts about 400º it comes with it s own bottle of a acid based flux. Flux residue distributed in a larger area represented by the circles a partial list of solvents with like solubility parameters to the flux residue soils in question are listed in figure 7. Rosin flux residuals may be left on the assembly or removed with a compatible solvent.

Flux residues being multi component soils require an engineered cleaning solvent to remove the soil. Cleaning solvents are used to remove oil grease solder flux and other contaminants. While this may be adequate for no clean flux where the goal is a visually clean pcb this may not be clean enough when more heavily activated fluxes are. Solvent based no clean wave solder flux superior no.

312 no clean flux is formulated for spray and foam applications in wave soldering and pcb assembly applications with a low solids content. Solvent based cleaning is a highly efficient method of cleaning by using a low boiling solvent composition to wash rinse and dry the assembly. Pcb cleaner is a cleaning chemical is suitable for the cold cleaning removal of post soldering flux residue manually by using brushes or with constant agitation. Rosin is hard not conductive and general corrosion resistant.

Rosin r flux is a combination of rosin and solvent best suited for clean and easy to solder surfaces.
