< Product > General Purpose Flux-Cored Solder Wire

Minimal Flux Spattering with Enhanced Wetting.

SN100C (033) is a general-purpose flux-cored lead-free solder wire that provides fast soldering and excellent finish after mounting. With reduced flux spattering, improved wettability, and fast melting, it is ideally suited for sequential soldering using automatic machines. Excellent wettability is provided on nickel as well as copper.

Reduced flux spattering at all temperatures

Test method
(Evaluation based on rework methods)

Tests were conducted at the temperatures of 350℃, 380℃ using the method applicable to repair of components without having a sufficient amount of solder during wave soldering.
