Solder Flux Cleaning Solvent

Rosin flux residuals may be left on the assembly or removed with a compatible solvent.

Solder flux cleaning solvent.

Cleaning solvents are used to remove oil grease solder flux and other contaminants. 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. 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.

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

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. Flux residues being multi component soils require an engineered cleaning solvent to remove the soil. Solvent based no clean wave solder flux superior no. 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.
