CW-201 Activated Flux-Cored Wire (SAC305, 0.025-inch, 1 lb Spool)
Indium Flux-Cored Wire
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:
- Void-free
- Evenly layer winding
- Low oxide shiny appearance over time
- Non-offensive odor for the 800 series and 200 series fluxes
Activated Flux-Cored Wire
Indium Corporation has developed a range of flux-cored wire solutions to meet the needs of virtually every electrical and non-critical electronic assembly and rework operation. Flux-cored wire solutions are created when the desired alloy, cored wire flux, and flux percentage are combined into a void-free, perfectly layer-wound package, which can be easily used for both hand soldering and automated wire feed solder. Indium Corporation prides itself on providing the industry’s widest range of flux-cored wire solders for both standard electronic assembly as well as highly specialized needs. No application is too large or too small.
Activated Cored Wire Flux Formulations
CW-201 Standard Activated Rosin: CW-201 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/37Pb and 60Sn/40Pb alloys on nonsensitive 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.
CW-207 Activated Rosin for Lead-Free: CW-207 is similar to CW-201 except that it is formulated using a blend of heat stable clear rosins. It is the standard option for soldering with lead-free alloy cored wire when soldering non-sensitive electrical or electronic applications, or when soldering moderately difficult-to-solder metals such as brass or nickel.
CW-209 Highly Activated Rosin: CW-209 is exactly the same as CW-207 except with twice the amount of halogen activator. It is recommended for use where CW-207 or CW-201 are not active enough to solder to highly oxidized metals, or where speed of wetting is a high concern.
