Popis: This paper focuses on the 3-D numerical methodology development of wafer level compression molding. With its successful application in a two-die-package embedded wafer level encapsulation, flow patterns, velocity, and pressure distributions are compared for different die size and die thickness. The computed flow-induced forces indicate which zone has a high risk of die sliding. The simulated molten molding compound flow fronts are compared with actual molding short shot samples. The key advantage of this numerical study is that it helps detect the molding defects quickly and improve moldability problems efficiently, in order to reduce manufacturing cost and design cycle time.
