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 (VOCs), 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
