TSF-6522
No-Clean Tacky Soldering Flux
Product Description
Kester formula TSF-6522 is a no-clean tacky
soldering flux formula designed to be used
with a rotating disc, a doctor blade, or a drum
fluxer. The TSF-6522 can also be used in
dot dispensing for BGA/PGA sites or in a
rework application for surface mount
packages. TSF-6522 maintains its activity
and dispensing characteristics for up to 8
hours and can be used in a wide range of
temperature and humidity conditions. Kester
maintains the highest standards by
manufacturing the TSF-6522 under a
vacuum environment.
