Solder Flux Cleaning Solvent

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.

Solder flux cleaning solvent.

Solvent based no clean wave solder flux superior no. 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. 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. 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.

Rosin flux residuals may be left on the assembly or removed with a compatible 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. Flux residues being multi component soils require an engineered cleaning solvent to remove the soil. 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.

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. 312 no clean flux is formulated for spray and foam applications in wave soldering and pcb assembly applications with a low solids content. Pcb cleaner 109 cleaning chemical is a mixture of high purity electronic grade polar and wax and activator residues which remains after soldering. Rosin r flux is a combination of rosin and solvent best suited for clean and easy to solder surfaces.
