The curing link (gel time) for epoxy resin is a crucial phenomenon, impact the fluidity and yield of modeling process. A survey of literature reveals that formed voids after the Molding Compound curing. In view of this, electronics manufacturers were not haven viscosity function to determine the process parameters of now product. The viscosity function is recommend in this research could provide prediction accurately. In practice, the phenomenon of process and material variation cause uncertainty of quality. The implement be used in this work include that computer-aided parametric design for experiment of viscosity function, artificial neural networks and location optimizing algorithms (CAFE) for gain the optimum process parametric. At the last, the confirmation experiment is used to proof that parametric recommendatory SN ration increased to 43.7% and 43.8%.
