159HF is a halide and halogen-free, neutral pH, water-soluble liquid flux. 159HF is formulated to provide excellent wetting and high-temperature tolerance. It provides excellent ionic cleanliness after water cleaning and has been formulated to minimize foaming in the wash process. 159HF is excellent for both wave and selective soldering applications. 159HF is also suitable for surface mount rework / touch-up soldering operations.
