An improved fast method for computing capacitance

In the design of chip carriers, appropriate analysis tools can shorten the overall production cycle and reduce costs. Among the functions to be performed by such computer‐aided engineering software tools are self and mutual capacitance calculations. Since the method of moments is slow when applied to large multi‐conductors systems, a fast approximate method, the average potential method (APM), can be employed for capacitance calculations. This paper describes the improved average potential method, which can further reduce the computational complexity and achieve more accuracy than the APM.
