Indium Corporation is quickly becoming known as one of the highest quality, full line suppliers of flux-cored wire solder. Indium Corporation uses only “conflict-free” and grade A (per ASTM B32) metals, as well as other high purity metals for its flux-cored wire. Our materials have been tested and certified to meet IPC J-STD-004B and other relevant industry specifications, including the legacy military specification QQ-S-571f. Indium Corporation’s flux-cored wire is well known for its evenly layer winding, low oxide shiny appearance over time, and non-offensive odor for the 800 series and 200 series fluxes. CW-201 Standard Activated Rosin is a traditional RA type flux as defined by the legacy Mil-Spec QQ-S-571. It uses traditional grade WW rosin and standard chloride activators. CW-201 is recommended for use with 63Sn/36Pb and 60Sn/40Pb alloys on non-sensitive oxidized copper parts, non-sensitive electrical/electronic assemblies where higher speed wetting is desired, assemblies where the residue is removed after soldering, and for soldering to moderately hard-to-solder metals such as brass and nickel.
