Indium CW-301

Sn63/Pb37 Halogen-Free 1.8%/2.5%/3.5% Water Soluble Flux Cored Solder Wire

CW-301 Wire Solder is cored with a high-reliability water-soluble flux that is compatible with Indium Corporation's full line of Pb-free soldering materials. It provides excellent solder spread with minimal smoking and low odor. The fast wetting speed is beneficial in minimizing rework cycle time which is typically longer with Pb-free solders.

Optimized for use with Sn63/Pb37 and Pb-free assembly and rework processes
Excellent cleanability with cold water
Fast and excellent wetting to common Pb-free surface finishes including: ImSn, ENIG, OSP, and ImAg
Minimal spattering and low odor
Resistant to charing
