Modeling of Anisotropic Shrinkage During Sintering of Low Temperature Cofired Ceramic Tapes
J Blendell, M R. Locatelli, Jay S. Wallace, B Hockey
One of the critical issues in advancing the use of cofired ceramic tape in electronic applications is the reproducibility of the shrinkage of the green tapes during sintering. The green tapes contain both volatile and nonvolatile components. The volatile components are removed during heating resulting in a porous material typically containing alumina particles and a glass phase. At the sintering temperature, the glass phase melts and the resulting liquid phase causes shrinkage by two processes. The capillary force of the liquid pulls the alumina particles together and rearranges the alumina particles. The driving force for these processes is the reduction of the liquid phase surface area.
