In this study, simultaneous viscosity and ionic conductivity data, obtained under isothermal and dynamic temperature conditions, were analyzed using models for rheological and dielectric behavior. The model parameters were evaluated from the experimental data using numerical optimization and linear regression techniques. Epoxy resins with different degrees of B-staging were used to study the effects of B-staging on the model parameters and the resin fluidity. The otpimum Dual Arrhenius model parameters for the Dow Quatrex 5010 and the two FR-4 resins are reported. The parameters were determined from viscosity data during dynamic cure at 5, 7, 10, 15, and 20°C/min heating rates. The predicted and the experimental viscosity profiles for the two FR-4 resins are also compared. The experimental data and the model predictions at 123, 135, and 157°C isothermal temperatures are compared.
