Research on the Failure Characteristics of Porous Ceramic Capacitor based on Numerical Simulation Technology

摘要

In the electronics industry, people has higher and higher demand for the performance of electronic products, but the requirement of volume is more and more small, it will promote the electronic products toward the direction of miniaturization. Porous ceramic capacitor is one of the most commonly used small electronic devices, but the capacitor thermal failure problem is always a difficult problem plagued capacitor design. This paper establishes the mathematical model of porous ceramic capacitors failure stress, and ABAUQS software is introduced to the failure simulation calculation process of porous ceramic capacitor, to establish the numerical simulation model of capacitor. Through the boundary conditions, the capacitor's maximum failure stress are calculated, the failure force and the relationship between the thickness of dielectric layer and ceramic layer are obtained, which provide a new computer method for the design of porous ceramic capacitor and the study.
