K100LD is a eutectic Tin/Copper alloy with controlled metallic dopants to control the grain structure within the solder joint, and to minimize the dissolution of copper into the solder pot. K100LD virtually eliminates the occurrence of common defects such as icicling and bridging.
K100LD Features:
• Prevent copper erosion and yield consistent soldering results
• Designed to give excellent wetting to through-hole and bottom side SMT components
• Dross-reducing technology results in 20% lower dross formation
• Lower cost than SAC305
• Produces shiny, smooth solder joints
Kester "331" Organic water-soluble flux is more effectivee than rosin flux when working with difficult-to-solder metals. Organic flux is more heat stable than most organic fluxes and the residue can be completely removed with a simple water rinse
