Kester 952S is a halogen-free, non rosin organic flux designed for wave soldering conventional and surface mount circuit board assemblies. The extremely low solid content (2%) and nature of activator system results in practically NO RESIDUES left on the assembly after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical testing and the expense of cleaning is eliminated.

Kester 952S exhibits improved soldering performance to minimize soldering bridges (shorts) and excessive solder defects. This non-corrosive and non conductive flux meets the strictest requirements of Bellcore TR-TSY-000078 specification. This flux is suitable for automotive, computer, telecommunications and photovoltaic applications where reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical organic water-soluble fluxes.

Ingredients: 2-propanol 88.7%-97.3%; Other 1%-8%; Activator 1.3%-2.5%; Wetting agent 0.2%-0.5%, surfactant 0.1%-0.3%
