The Kester 2220-VF is a high activity, organic flux designed for lead-free automated wave solder applications. The flux will provide maximum capillary wetting action up plated through holes, making it ideal for use on multilayer boards. Along with this enhanced activity, 2220-VF flux produces bright, shiny solder joints and the residue after soldering is effectively removed in standard water cleaning systems. - 2220-VF is free of volatile organic compounds (VOC), which provides optimal heat stability for the lead-free wave soldering process. The use of VOC-free solvents eliminates the use of ozone depleting chemicals which results in an environmentally friendly process.
