Abstract:	The electronics industry is characterized by rapid technological advances. Increase in number of I/O interconnections on chips and need for more compact assemblies is forcing designer to consider multilayer ceramic packaging. With the advancement in co-fired technology, the green tapes are becoming widely used now, and will be even more so in the future. There is considerable knowledge and expertise on the preparation of multilayer ceramic materials but little information is available on the handling of laminate ceramic green sheets with automated tools. In this thesis, we will analyze the displacement, the principal and shearing stress of the different sized laminated green sheets when they are handled by either two-holder or four-holder pick-up tools. The analysis was carried out with the FEM modules in the IŽDEAS package. The results are used to study the different influence of the two-holder and four-holder pick-up tools. A conceptual design for adjustable four-holder pick-up tool was proposed for handling and stacking the laminated multilayer ceramic green sheets.
