Optimisation of Slurry Compositions for Improving the Mechanical Properties of Low Temperature Co-Fired Ceramic (LTCC) Tapes

Abstract In the era of miniaturization and hybridization, quest for novel materials multilayer packaging had been increased. The includes High Temperature Co-Fired Ceramics (HTCC), LTCC ULTCC. which is mixture ceramic glass (which reduces firing temperature ceramics) has attracted many researchers due to its lower temperature(<900°C). Due this sintering temperature, it can be cofired with low resistance metals like Ag Au increases value in field. standard package fabrication process uses form tapes. Each layer processed separately punching, via filling Screen printing then stacked, laminated sintered get a package. green sheet should have sufficient adhesion carrier film as well mechanical properties withstand processes that undergoes. These are mainly affected by organic compositions used slurry preparation. tape casting was prepared blending powder solvents, dispersants binders predefined time ball mill. casted on Mylar continuous caster varied thickness. present study aims at reporting effect plasticizers tape. starting material Cordierite Anorthite based recrystallizable through solid-state method. characterised phase purity, microstructure elemental using XRD, FESEM EDAX. tapes were thickness, uniformity, density, surface defects such pinholes cracks, tensile strength. dielectric thermal also evaluated. results reported.
