Various methodologies of wire sweep analysis have been introduced to get better prediction and matching the experimental measurements by many researchers. As more and more high pin-count packages (such as BGA, QFP) are used today, efficiency has become an important requirement besides accuracy for software used to predict wire sweep in IC packaging. This study introduces a newly developed wire sweep analysis solution (InPack), not only to meet the need of accuracy, but also enhance the efficiency for actual applications. It combines global flow analysis (C-MOLD) and structure analysis (ANSYS) to become a solution for general wire sweep analysis.
