AIM will highlight its lead-free soldering materials, including the
SN100C lead-free alloy. A live lead-free selective soldering
demonstration with the alloy is in booth 5437. SN100C, created by Nihon
Superior in Japan, is comprised of tin, copper and a small amount of
nickel. The nickel modifies its behavior so that in wave soldering it
exhibits fluidity comparable with tin-lead solder. Excess solder drains
easily off the joint, so bridges and icicles are avoided. Provides
smooth, bright, well-formed fillets which make inspection easy. Does
not contain silver or phosphorus, is less aggressive toward the copper
of traces and pads or the stainless steel components of soldering
equipment. Has a low dross rate.
