Flux-Cored Solder Wire

SN100C (030)

Low Carbonizing Lead-Free Flux-Cored Solder Wire

The flux-cored solder wire enables fast soldering with less carbonizing of soldering tips and less flux spatter providing greater productivity than existing products.

SN100C (031)

Reduced flux spattering

SN100C (031) is a general purpose flux-cored lead-free solder wire that offers improved productivity. The alloy and cored flux combination provides excellent wetting for components with poor solderability.solder wire provides fast wetting, resulting in faster soldering.

Flux Spattering Test

Solder each wire with a tip temperature of 280℃ to 380℃.
Count the number of spattered flux droplets around each soldered wire.


Flux Spattering Test Result

Dramatic reduction in Flux spattering


SN100C (551CT)

Improved flux activity and durability

With sustained activity and good separation of the solder from the tip with a consequent reduced incidence of icicles, high reliability SN100C (551CT) is Ideal for sequential soldering and rework.
