WebSuperior HASL-1 hot-air solder leveling flux is a non-chloride activated, water-soluble, non-flammable organic flux specially formulated for hot-air solder level soldering processes in vertical and linear PC fabrication processes. Formulated for high temperature solders, this flux is stable and active during the heat cycle to promote rapid solder wetting to metal … WebHASL is an acronym for “Hot Air Solder Leveling”. It is a widely used surface finish process in printed circuit board manufacturing. This process involves applying a layer of molten solder to the exposed copper traces and pads and then using hot air to level and smooth the surface. HASL is the second most used surface finish.
