Product Description

Kester 988 flux is a low solids, no-clean flux that is specially designed for excellent solderability and best-in-class through-hole fill in lead free wave soldering process. The residue left behind is evenly distributed and non-tacky so that boards are cosmetically clean as they exit the wave solder machine. The residue remaining after soldering is non-conductive and can be left on the boards without degrading the reliability of the assembly. Kester 988 is classified as Type ROM0 flux under J-STD-004A specifications.
