Indium WF-9942 ORL1 No-Clean Wave Solder Flux

Physical Properties

WF-9942 is almost colorless, indicating that it is rosin-free. The solvent blend ensures even distribution of flux solids both during storage and during spray flux deposition. The specific gravity of WF-9942, 0.828 @ 25°C, is measurably higher than that of pure isopropyl alcohol. However, in contrast to higher solids content fluxes, specific gravity is not the best method to control the quality of WF-9942. This is because flux solids content is relatively low and small amounts of water contamination can confuse specific gravity measurements. While in-process quality control of WF-9942 is not generally required, the best method is to ensure both solids content and activity level is by acid value titration.
