ASTM D770 (currently on revision 11) is the usual specification for isopropyl alcohol revealed by ASTM International. Isopropyl alcohol (CAS # ) can be referred to as IPA, isopropanol, 2-propanol, and even rubbing alcohol. It dissolves a extensive range of polar and non-polar soils, is it’s often used to dissolve and take away light oils, fingerprints, chopping fluids, flux residues, carbon deposits, and mould release. It can also be readily miscible in water, so can be used as a drying agent as properly. In our testing, an exact straw angle of 30o, 45o, or 60oto the board has no differing impact on the cleanliness of the board.

Fleet Maintenance

The dry time is tremendously increased as the percentage of water within the alcohol solution is increased. This could be an advantage or drawback relying on the applying. For instance, isopropyl alcohol is usually used as a flux remover to take away flux residues from round solder joints. Technicians tend to prefer a fast dry time in order that they can clear the electronics and bring them again into service as rapidly as attainable. When breaking down and removing thick, gummy, or baked-on materials, more dwell or soak time is required.
