Development of Reliability Verification System for Robust Package Design

To achieve design for reliability (DFR), a reliability verification system (RVS) was developed. Package level and board level reliabilities were predicted by the developed system automatically and the design for six sigma (DFSS) was achieved. Process server and database server were developed. FEM mesh was generated automatically by well-organized builder, simulation conditions were assigned by standardized procedure, and reliabilities were calculated by developed life models. All data related to the simulation were managed by database system. High quality simulation was carried out easily and quickly. Robust package design was achieved by design optimization using the RVS.
