WBF4100 is a water-based, no-clean flux designed for mass production in leaded and lead free application. This flux has no halide in its activator system, hence, reduces the possibility of corrosion and short circuits due to the presence of active ions. WBF4100 is finely tuned to offer shiny solder connection and the best solderability in electronic assemblies.
