In this paper, the behavior of BGA solder joints microstructures was studied as a function of Ni doping in SAC solder. Three kinds of solder compositions were selected including Sn3.0Ag0.5Cu, Sn1.0Ag0.5Cu and Sn1.0Ag0.5Cu0.02Ni to value the influence the effect of Ni doping, OSP and Au/Ni pad was employed on the PCB side. Emphasis was placed on studying the effect of low level doping with Ni on the...
RF-MEMS is one of the most potential applications for MEMS products. Eutectic solder wafer bonding is one of the attractive methods for RF-MEMS wafer level packaging. A process of gold-tin hermetical wafer bonding was developed in SAIT, Korean. Different UBM systems and thin films of gold-tin were deposited on cap wafer, RF-MEMS device wafer and substrate wafer (if needed). The bonding was performed...
