Investigation of High Temperature Co-fired Ceramic tapes lamination conditions

The main goal of this paper was to analyze the influence of lamination process conditions and High Temperature Co-fired Ceramic (HTCC) tape composition on the lamination quality (existence of delaminations). The second aim was to estimate the influence of lamination conditions and HTCC tape composition on three process outputs: compressibility, surface roughness and density of High Temperature Co-fired Ceramics and to recognize if these outputs can be useful from lamination quality investigation point of view. The bonding quality was investigated using scanning acoustic microscopy (SAM). The analyzed ceramics was fabricated using water based slurries in the frame of tape casting process. The paper additionally discusses limitations and drawbacks of the used investigation methods and experiment design. (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
