Electromagnetic Analysis in PINMAP Assignment Optimization Based on T-matrix Method

In this paper, the pin map scenario is modeled as a parallel-plate structure for electromagnetic leakage analysis by approximating the solder balls as cylinders. The boundary field and internal field distribution under multiple radiation coupling sources with different amplitudes and phases are analyzed by the T-matrix method based on virtual PMC cylinders. Simulations show that the calculation results are accurate and much faster than those obtained by the commercial software.
