63-0000-0197

The 63-0000-0197 is a Mildly Activated Rosin Flux features homogeneous solution of high quality purified Grade WW rosin in a specially blended alcohol vehicle into which a very small amount of an extremely effective activating agent has been incorporated. Kester 197 is classified as type ROL1 flux under IPC ANSI/J-STD-004 joint industry standard. The Kester 197, under MIL-F-14256, was QPL approved as type RMA. Kester 197 flux has been developed for soldering of critical electronic and electrical assemblies where a more active flux than plain rosin is required but where highly activated flux is considered potentially conductive. Kester 197 flux is formulated for foam fluxing applications in automatic wave solder machines. The surface tension has been adjusted so that a low air pressure will produce a very uniform head of small bubbles. This flux can also be applied by dipping, brushing or spraying methods.
