This work quantifies how increasing levels of modelling simplifications decrease the accuracy of PCB FE models. This is achieved through a sensitivity analysis of simplification techniques for FE circuit board models. The work uses a very large range of input and output values to determine the effect of variation in boundary conditions, PCB thickness, component types, MAC, natural frequency and a range of other variables. It is an important first step in determining variation and is an essential precursor to the second more practical paper: “Sensitivity analysis of simplified Printed Circuit Board finite element models”. Also many useful practical observations are made, such as the importance of accurately determining boundary condition effects.
