“…Our current research included fabricating and using Ni foam reinforced Sn composite solder foils to solder Cu alloy and Al alloy, and it revealed that the use of Ni-skeletons and Ni-Sn reactants significantly increased the strengths of joint [6] , [7] . The analysis results show that continuous reticular structure inhibits the aggregation of the reinforcing phase and improves the combination between Sn solder and reinforcing phases [8] .…”
