Halogen Free Products

Recent increasing consciousness about ecology on a global scale has started considerations for the restriction of certain elements within soldering materials used within the electronics industry.
Ever since it has been reported that dioxins can be generated when specific kinds of halide are combusted, there have been moves afoot to eliminate halogens from soldering materials.
Koki research and development team have been working on this Halogen free issue for many years, and offers true Halogen free solder pastes.
