Defects of Base Metal Electrode Layers in Multi-Layer Ceramic Capacitor

摘要: An ultra-thin Ni-based metal used as the electrode layer in multilayer ceramic capacitor determines dielectric performance of capacitor. The warpage and continuity inner layers, a dihedral angle between BaTiO3 layers electrodes two capacitors (X7R X5R) were characterized by optical microscopy scanning/transmission electron microscopes. results show that chips is closely related to discontinuity electrode. takes place mainly because Rayleigh instability Ni layer, but less induced tensile stress from sintering.
