The influence of particle size of slurry on life on BME‐MLCC

Abstract Four slurries and base metal electrode multiplayer ceramic capacitor (BME‐MLCC) samples（0603‐X7R‐50V‐104）were prepared by using different grinding ways. The particle sizes of slurries were characterized by grading analysis and the micro‐morphology of films and samples were analyzed by scanning electronic microscopy (SEM). The structure was characterized by X‐ray powder diffraction (XRD). Finally, the life of samples were tested by highly accelerated life testing (HALT). Results showed that the particle size distribution of slurry which was made using smaller grinding media by sander was narrow. The micromorphology of as‐prepared films and samples were more tightly, the numbers of particles in single dielectric were more, the initial reliability was better and the life was longer.
