No Clean Flux
Kester 922-CX is a non-rosin, organic flux designed for wave soldering conventional and surface mount circuit board assemblies. This flux eliminates defects often experienced in surface mount assembly wave soldering operations with traditional fluxes. This non-corrosive and non-conductive flux has an extremely low solids content. There is essentially no residue left on the assembly after soldering. There are no residues to interfere with electrical testing and the expense of cleaning is eliminated. A particular feature of 922-CX is the very dry appearance of PCB assemblies as they exit the wave solder machine. Although cleaning is eliminated, the flux will not harm the electrical reliability of the assembly.
