Implementation study of intelligent system for IC transfer molding process

Various problems occurred in encapsulation of plastic IC packages are the results of improperly handling of the many process parameters, lack of understanding of material properties, and immature mold design. The traditional way to get rid of these problems is to adjust the process parameters of the transfer molding machine. However, the optimization of these parameters is usually based on past experiences or obtained by trial and error. This approach is time consuming and less accurate. A program in developed to help users to choose an appropriate initial machine setting based on the machine, material and mold design information. The detail of its application to IC encapsulation process is described in the paper
