Abstract

The nonlinear properties of elastic modulus of the resin in relation to curing degree of the resin was defined through the phenomenological model. The finite element model of LTCC-metal assembly, which belong to the radio frequency (RF) function layer, is established by ABAQUS. When curing pressure is determined, the effect of different curing degree on the elastic recover of conductive particles is given under the same curing temperature, and the influence of different curing temperature on the deformation of conductive particle is also given under the same curing degree. Therefore, the curing degree increased is able to increase the contact area of conductive particles so as to reduce the contact resistance, but at the same time, the interconnection interface residual stress also increased, thus easy to cause the stratification. However, when the curing degree is determined, the contact area increased firstly, and then gradually decrease as the curing temperature increases, and when used in curing at lower temperature, the curing time increased accordingly, it will influence the economic benefits.
