Kester R520A is a lead free, organic acid,
water-soluble solder paste formula specifically
designed for use with the higher temperature
Pb-Free alternative soldering alloys such as
Sn96.5Ag3.0Cu0.5 (SAC Alloys). The solder paste
exhibits long stencil life and tack time, while still
delivering exceptional solderability to a wide variety
of metallic substrates. R520A was formulated to
release consistently from the stencil for those critical
fine pitch applications (0.5 mm/20 mils) with
anti-slump characteristics and preferred solder
deposit definition. The activator package in this
formula is extremely aggressive, providing superior
wetting to OSP coated and Immersion Gold over
Electroless Nickel (ENIG) boards. R520A is an
extremely stable water-soluble formula.
