WebIn 2001, TI converted from a nickel-palladium (NiPd) lead finish for components to a nickel-palladium-gold (NiPdAu) lead finish. The NiPd finish for IC leads was first introduced in the late 1980s.[1,2] By October 2001, more than 40-billion NiPd-finished IC packages were in the field. The four-layer NiPd structure is shown in Figure 1.
