Analysis on the Deflection of Multi-Layered Ceramic Capacitors Due to High Pressure

Abstract

The deflection of multi-layered ceramic capacitors (MLCCs) due to high pressure was investigated. Classical laminated plate theory and linear elastic assumptions were adopted. Three boundary conditions are considered, such as all edges simple-supported, two simple-supported and the other two free, and all free. Four corners fixed and the elastic foundation at the bottom are added. Finite element method (FEM) with software ANSYS was used to obtain the displacements. Compared with numerical results, the analytical solutions of two cases were acceptable, such as four edges free and two edges simple-supported and the others free with the errors 0.1–6.2%.
