WB200 is a low-VOC halide-free, rosin/resin-free, low solids no-clean flux which provides excellent activity for defect-free soldering. It is formulated with a proper mixture of organic activators which deliver excellent wetting and top-side hold fill, even with OSP coated bare copper boards which have undergone prior thermal excursions.
The formulation ensure to reduce the surface tension between the solder mask and the solder, thereby, dramatically reducing the tendency of solder ball generation. Also, reduce the occurrence of solder bridging.
