Zusammenfassung:An advanced multiyear electronic packaging project has been started. The project is a comprehensive interactive one involving theory, modeling, structure fabrication, and reliability testing. Highlights of the first year's activities are presented in this report. Important results include: the creation of integrated thermal and thermomechanical models, the prediction of lifetimes under environmental and operational stress conditions, model verification and validation by carefully controlled experimentation, development of assembly techniques, and the invention of a new method for preparing controlled solder joint height and geometry. Keywords: Electronic packaging; VLSI/VHSIC packaging; Thermal analysis; Thermal modeling; Finite-element modeling; thermomechanical analysis; Chip carriers; Solder reflow.
