Kester Lead-Free Silver-Free Solder Sn99.3 Cu.07 (K100LD) #48 Rosin / .020" dia. / 3.3% Core (24-9574-1401)

Kester 24-9574-1401• A Low Cost Alternative to SAC-305

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.

Kester "48" Activated Rosin Flux for cored solder wire was developed for lead-free applications to enable soldering of most common metals. 48 has performance characteristics far exceeding standard RA fluxes. 48 builds on the performance of its predecessor Kester 44 with “instant-action” wetting to provide fast and reliable solder joints.
