Description/Abstract
This paper presents a method for determining the accuracy lost when using different finite element “smearing” methods for electronic equipment, these methods are used to reduce modelling time and complexity by averaging the added component mass and stiffness over the PCB area. This paper presents a method to statistically quantify the accuracy lost. In addition, several important observations have been made about the general shift in accuracy for the smearing methods. The work is highly relevant for anyone wanting to create simple and quick FE models of electronics, whether in academia or industry, allowing considerable time/cost savings and improved confidence in results.
