This paper presents an improved PEEC model, in order to facilitate the use of scale-down techniques in the analysis of large-scale interconnect packaging structure, which describes the system state equation instead of a specific equivalent circuit for which it is the vector magnetic bit integral The expression and Lorentz standard replace the integral expressions of vector magnetic and scalar potentials and expand the integral equation, which can avoid the extraction of capacitance matrix in complex medium structure and save the calculation time greatly. This model is convenient Embedded in a larger system for hierarchical and comprehensive analysis and the use of PVL and other scale-reduction techniques.The numerical results agree well with other documents, indicating that the method has high reliability
