Synthesis Of TiO2 Nanoparticles And Characterization Of Sn-3.0Ag-0.5Cu/TiO2 Via Nanoindentation And Selective Electrochemical Etching

Distributions of incorporated TiO2 nanoparticles in the Sn-3.0Ag-0.5Cu (SAC305) solder alloy were investigated by nanoindentation and selective electrochemical etching. Optimum size of the TiO2 reinforcement particles were obtained by the sol-gel centrifuge precipitation method. The SAC305-TiO2 comp...
