Simplified modelling of printed circuit boards for spacecraft applications
Simplified modelling of printed circuit boards for spacecraft applications
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. This conference paper later became a journal paper of the same title.

Abstract
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. This conference paper later became a journal paper of the same title.
