Materials interaction during soldering and isothermal ageing of Sn-Pb and Sn-Ag-Cu solders on electroless Ni/Au surface finish

In flip chip interconnection an under bump metallurgy (UBM) is required to provide a diffusion barrier, an adhesion and a solderable surface. Among the various UBM systems available the electroless nickel / immersion gold (ENIG) has received greater attention in recent years due to its low cost and...
