Henkel Loctite has introduced a new VOC-free, no-clean liquid flux designed to reduce solder balling defects. Called Loctite Multicore MF300, this high activity flux targets tough-to-solder surfaces such as oxidized copper. Non-flammable and halide free, MF300 is a low residue flux that meets U.S. air quality legislation. This resin-free liquid flux can be used in conjunction with most commonly used surface preservative materials, and it passes stringent Bellcore electromigration and J-STD-004 surface insulation resistance tests without cleaning.
