This item was taken from the IEEE Conference ' Simulation Calculation of Mechanical Performance of Particle Filled Electronic Packaging Polymer ' Electronic packaging polymers filled with various solid additives such as silica, flame retardant, etc. have excessively been required for the use in advanced IC packages in recent years. It's necessary to predict the mechanical properties of these electronic packaging materials. On the basis of structural and mechanical characterization of particle filled epoxy materials, a new three-phase (dispersion phase, interface phase, and continuous phase) constitutive model and its simulation calculation are performed for the mechanical properties of the particle filled electronic packaging polymer in this study. In this paper, the interface chemical principle and three phase constitute model are combined, which improve the mechanical property's calculation and composition design method of electronic packaging polymer. With this model, the relationship between mechanical properties of the electronic packaging materials and modulus of matrix, solid particles content, particle size, gradation and thickness of the interface adhesive layer were constructed mathematically. This relationship and its derived patterns can be used in not only the prediction of the mechanical properties of electronic packaging materials but also the instruction of the composition design for particle filled electronic packaging materials.
