A Fast Calculation Method of QFP Packaging PIN Conductor Inductance

In this paper, a simplified method for calculating inductance of multiple microstrip lines (PIN conductors) is proposed. Taking the simplified calculation method of QFP packaging PIN conductors inductance as an example, with establishing the equivalent model and calculating their inductances by dividing the smallest units in parallel, and then it compared with the equivalent model inductance extracted by the professional electromagnetic simulation software HFSS, which proves that the simplified method is effective. By comparing the errors between the inductance calculated by the algorithm and the inductance of the equivalent model, the accuracy of the inductance parameters extracted by the method is verified from the engineering point of view. This method is easy to extract the inductance of PIN conductor encapsulated in QFP, and has great practical value.
