Effect of Ag-decorated MWCNT on the mechanical and thermal property of Sn58Bi solder joints for FCLED package

Research Status of Evolution of Microstructure and Properties of Sn-Based Lead-Free Composite Solder Alloys

“…They demonstrated that the IMC thickness of composite solder joints was inhibited because of the doping of Sn-MWCNT nanoparticles and the best addition was 0.1 wt% considering the mechanical properties of solder joints. Additionally, they also demonstrated that the doping of Ag-MWCNTs was effective to suppress the growth of IMC thickness of Sn-58Bi solder joint [35]. Similar phenomenon was also observed in the Sn-58Bi solder with the incorporation of Ni-coated CNTs [103] and Cu-coated CNTs [104].…”

“…Moreover, the novel carbon-based nanometer materials, such as CNTs and graphene, are also selected to adjust the Sn-Bi solders. Lee et al [35,61] investigated the influence of Sn-decorated multiwalled carbon nanotube (MWCNT) nanoparticles and Ag-decorated MWCNT on the transformation of microstructure of Sn-58Bi solder. They demonstrated that the IMC thickness of composite solder joints was inhibited because of the doping of Sn-MWCNT nanoparticles and the best addition was 0.1 wt% considering the mechanical properties of solder joints.…”

“…It was found that the tensile strength of composite solder was proportional to the doping of MWCNTs, which increased by 47.6% when the addition of MWCNTs was 3 wt%. Lee et al [35,61] investigated the influence of Sn-decorated MWCNT nanoparticles and Ag-decorated MWCNT on the mechanical properties of Sn-58Bi solder. They found that the doping of Sn-decorated MWCNT nanoparticles could improve the mechanical properties and the optimum addition was 0.1 wt% [61] and the 15 Journal of Nanomaterials fracture energy and shear strength increased by 80% and 16%, respectively, when the addition of Ag-MWCNTs was 0.05 wt% [35].…”

He et al [108] demonstrated that the bending strength of Sn-58Bi-0.03CNTs composite solder increased by 10.5% compared with the plain Sn-58Bi solder.…”

“…Consequently, trace amount of alloying elements (Ni [8][9][10], Mn [11], Bi [12], Co [13,14], Cr [15], Al [9], Sb [10], Fe [16], and rare earth (RE) [17,18]) is incorporated with Sn-based lead-free solder to enhance the comprehensive properties. Moreover, with the popularity and utilization of nanometer materials fabricating technology, the nanometer particles are doped with Sn-based lead-free solder to improve the comprehensive properties, such as nanometer oxide (Al 2 O 3 [19][20][21], BaTiO 3 [22], Y 2 O 3 [23], TiO 2 [24][25][26][27], and ZrO 2 [28,29]), nanometer carbide ( [30,31]), nanometer IMC (Cu 6 Sn 5 [32][33][34]), and carbon-based nanometer materials (carbon nanotubes (CNTs) [35][36][37], graphene [38][39][40], and fullerenes [41][42][43]). Generally speaking, the addition of nanoparticles acts as reinforcing phase in the Sn-based lead-free composite solder alloys.…”
