초록
The demand for reliable multilayer ceramic capacitors has significantly increased in automobile, aerospace, and 5G networkindustries. Therefore, the utilization of Ag-epoxy electrodes for the development of highly reliable MLCCs has becomeessential. In this study, the changes in mechanical and thermal stress caused due to the utilization of Ag-epoxy electrodes wereanalyzed using 3D finite element analysis. Subsequently, the reliability of the MLCC was evaluated using the board flex,thermal shock, and temperature-humidity-bias test. A comparison between the simulation results was performed and it wasobserved the bending resistance of the soft termination type multilayer ceramic capacitor with Ag-epoxy electrode wasincreased. Additionally, solder deterioration due to thermal shock was prevented, and it had excellent moisture resistance
