Solder Flux Cleaning Solvent

Solvent based cleaning is a highly efficient method of cleaning by using a low boiling solvent composition to wash rinse and dry the assembly.

Solder flux cleaning solvent.

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. Cleaning solvents are used to remove oil grease solder flux and other contaminants. Flux residues being multi component soils require an engineered cleaning solvent to remove the soil. In the snap program the cleaning solvent sector refers to substitutes for non aerosol solvents used in industrial cleaning in vapor degreasing cold batch cleaning or automated cleaning equipment.

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. The most common way to clean flux residues from a repair area is to saturate a cotton or foam swab with isopropyl alcohol or another cleaning solvent and rub it around the repair area. 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. 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.

312 no clean flux is formulated for spray and foam applications in wave soldering and pcb assembly applications with a low solids content. Rosin is hard not conductive and general corrosion resistant. Pcb cleaner 109 cleaning chemical is a mixture of high purity electronic grade polar and wax and activator residues which remains after soldering. Solvent based no clean wave solder flux superior no.

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.
