Features: VOC-FreeLead-Free CompatibleHalide-Free Low Post Process ResidueBroad Process WindowExcellent Wetting : 270WR is a VOC-free water-based, halide-free, no-clean liquid flux formulated to offer a very wide process window allowing for extremely good wetting, even to difficult-to-wet materials. 270WR offers a broad activation range, proving to be an excellent flux for a variety of process parameters and applications, including lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper, and other alloys. 270WR offers low post-process residues and has proven to reduce preventative maintenance requirements for spray fluxing applications. In addition, 270WR offers low-fuming and fast solvent evaporation for a VOC-free flux. 270WR is designed to be a no-clean, non-visible residue flux, which can be cleaned if critical to the product application. Application: - 270WR is ready to use directly from the container for spray systems. - When spray fluxing, it is imperative that proper flux coverage and uniformity be achieved and maintained. A dry flux coating of 500 to 1500 micrograms per square inch is necessary. - When complete nitrogen sealed wave solder equipment is used, it is generally necessary to apply slightly more flux than normal as a result of excess drying due to the extended length of the equipment. Cleaning: 270WR can be cleaned, if necessary, with water, and enhanced cleaning can be achieved through the use of a saponifier. Deionized water is recommended for the final rinse. A temperature of 38C - 65C (100 - 150F) is sufficient for removing any residues. An in-line or other pressurized spray cleaning system is suggested, but is not required.
