What is Isopropyl Alcohol ?

Isopropyl alcohol (also referred to as CAS #67-63-0, IPA, isopropanol and 2-propanol) dissolves a wide range of polar and non-polar soils, including light oils, fingerprints, cutting fluids, flux residues, carbon deposits, and mold release.

For electronic printed circuit board (PCB) assembly, isopropyl alcohol is used to clean flux residues from recently soldered circuit boards and in both PCB repair and rework. IPA is also used to remove solder paste and adhesive from SMT stencils. Maintenance cleaning with isopropyl alcohol is common for removing caked-on and burnt-on flux from SMT reflow ovens, wave soldering fingers, selective soldering nozzles, pallets, and anywhere else flux tends to collect in automated soldering processes.
