A new technical paper titled “ILP-Based Substrate Routing with Mismatched Via Dimension Consideration for Wire-bonding FBGA Package Design” was written by researchers at National Taiwan University of Science and Technology.
“In this paper, we propose an integer linear programming (ILP)-based router for wire-bonding FBGA packaging design. Our ILP formulation not only can handle design-dependent constraints but also take the problem of mismatched via dimension into account, which is caused by the mechanical processes and greatly increases design complexity,” states the paper.
