Almit Technology has extended its range of solder materials with the addition of the SR-37 LFM-22S lead-free cored solder wire. Developed to reduce material cost, the new formulation also enhances cost-efficiency and yield through a range of tip-saving properties. The no-clean cored solder wire has been developed for manufacturers who do not require silver in lead-free materials. By removing this element from the mix, the company has substantially reduced material cost to increase the accessibility of its solder technology. The cored solder wire also incorporates the SR-37 flux to deliver a cost-efficiency for lead-free manufacture. The flux is designed specifically for use with lead-free alloys, providing fast wetting to all materials without exception. Since the LFM-22S alloy is based on a modified tin/copper formulation, its combination with the SR-37 flux slows down erosion of soldering iron tips. By ensuring that after soldering, a small amount of flux remains on the soldering iron tip, the SR-37 LFM-22S prevents further oxidation from taking place and allows the iron to transfer heat readily to the next joint. The result is fast-wetting, consistent flux content and tip-saving properties for high yield and high value.
