Solder joints of Cu/Sn-3.5Ag were prepared using Cu foil or electroplated Cu films with or without SPS additive. With a high level of SPS in the Cu electroplating bath, voids tended to localize at the Cu/Cu 3 Sn interface during subsequent aging at 150 ยฐC, which was highly detrimental to the drop im
