Abstract
Due to the Piezoelectric Characteristic of the MLCC Dielectric BaTiO3, the Multilayer Ceramic Capacitor (MLCC) Can Vibrate When the Supply Voltage Has AC Components. the Vibration of the MLCC Will Generate a Force on the Printed Circuit Board (PCB) It is Connected To, Causing the PCB to Vibrate as Well. the MLCC Vibration-Generated Force is Extracted using a Measurement-Simulation-Based Methodology in This Paper. the Force of an MLCC is First Extracted at the PCB Resonance Frequencies. Then, a Broadband Force Profile is Obtained by using the Interpolating Method. the Extraction Methodology Can Be Used in Different Boundary Conditions, on Different PCBs, and for Different MLCCs with a Good Generalization.
