Isopropyl alcohol for the electronics industry
Isopropyl alcohol (also known as IPA, isopropanol or 2-propanol) is the most commonly used solvent in the electronics industry. This is because it is compatible with most materials used in electronics equipment and, unlike electronics-grade ethanol, never leaves oil traces.
Electronics-grade isopropyl alcohol dissolves a wide range of polar and non-polar soils, and is used to remove everything from fingerprints and light oils to flux residues and cutting fluids. It is also widely used for printed circuit board (PCB) assembly, cleaning and repair work, for which a minimum 99.9% grade isopropyl alcohol is advised.
And finally, because isopropyl alcohol is miscible in water and evaporates rapidly, it also works as a highly efficient drying agent.
