Modeling of Advanced Multilayered Packages with Multiple Vias and Finite Ground Planes

Abstract

A system-level modeling approach, which combines the MoM (method of moments) and the SMM (scattering matrix method) has been presented for the modeling of advanced electronic packages (Oo et al., 2007). The focus of this paper is on addressing the problems of multilayered multiple via coupling and finite ground effects by the SMM method. Significant extensions of the SMM method facilitate the modeling of coupling among densely populated vias in multilayered packages with finite power/ground planes. The proposed approach is suitable for the signal and power integrity, and even EMI analysis of packages at system level.
