Take Sn/Cu as basis jointing a trace of Ni and P becoming lead-free Sn/Cu/Ni alloy to improve solder’s wettability and liquidity. It is able to reduce IMC formation rate and has marvelous solder joint performance in wave soldering and HASL process than Sn/37Pb alloy. Meanwhile its solder joint performance in lead-free wave soldering is smoother and brighter than high silver content alloy such as SAC305.
