Impedance formulas of a bond wire array with analytical method of moments (MoM)

The analytical moment method (MoM) is used to analyze the equivalence of a bond plate and an array of bond wires and some equations have been derived. To verify the validity of the proposed theory, several structures with different dimensions of bond wires have been analyzed and simulated up to 10 GHz. In case of different bond wire configurations, good agreements have been achieved between the theoretical analyses and simulation results. With the help of the proposed analytical method, the computing time of bond wires by commercial electromagnetic calculation software can be tremendously reduced.
