Optimization of Solder Joint Fatigue Life Using Product Model-Based Analysis Models

Abstract

Product Model-Based Analysis Models (PBAMs) have been presented as highly automated analysis modules for designer usage. Previous examples such as solder joint fatigue PBAMs have shown how explicit design-analysis associativity linkages enable seamless interfaces to solution tools (e.g., finite element analysis systems). These examples focused on using PBAMs for design verification, where a criteria such as fatigue life was checked given one design state as an input. This paper presents a technique which utilizes PBAMs for design optimization. An example is given which maximizes solder joint fatigue life by iteratively changing PBAM inputs (the design variables) based on PBAM outputs (the analysis results). Benefits of the technique include the modular and flexible addition of an optimization agent to existing analysis modules.
