Kester Ultrapure K100LD Soldering Bar

Ultrapure Soldering Bar

Kester Ultrapure K100LD Soldering Bar is a near 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. The improved grain structure also results in shinier solder joints than traditional lead-free alloy alternatives.
