Effect of Densification Mismatch on Camber Development during Cofiring of Nickel-Based Multilayer Ceramic Capacitors

[[abstract]]The development of camber during the cofiring of a two-layered structure of Ni-electrode/BaTiO3-dielectric as a function of temperature has been investigated. At a given thickness of Ni electrode, less camber and camber rate with increasing thickness of BaTiO3 dielectric have been observed. This phenomenon is attributed to the densification mismatch between the Ni electrode and the BaTiO3 dielectric during cofiring. The mathematical analysis of camber development, based on a viscous model, shows significant agreement with experimental observations.[[fileno]]2020313010035[[department]]材料
