The small amount of nickel in SN100C modifies its behavior so that in wave soldering the resultant alloy exhibits fluidity comparable with that of traditional tin-lead solder, AIM said in a press release. The result is that excess solder drains off the joint and bridges and icicles are avoided. The nickel also provides smooth, bright and well-formed fillets, AIM said.
SN100C contains no silver or phosphorus, and is not aggressive toward copper traces and pads or stainless-steel components of soldering equipment.
