The development of camber during the cofiring of a two‐layered structure of Ni‐electrode/BaTiO 3 ‐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 BaTiO 3 dielectric have been observed. This phenomenon is attributed to the densification mismatch between the Ni electrode and the BaTiO 3 dielectric during cofiring. The mathematical analysis of camber development, based on a viscous model, shows significant agreement with experimental observations.
