    Avoiding Inelastic Strains in Solder Joint Interconnections of IC Devices addresses analytical (mathematical) modeling approaches aimed at understanding the underlying physics and mechanics of the behavior and performance of solder materials and solder joint interconnections of IC devices. The emphasis is on design for reliability, including probabilistic predictions of the solder lifetime.


    • Describes how to use the developed methods of analytical predictive modeling to minimize thermal stresses and strains in solder joint of IC devices
    • Shows how to build the preprocessing models in finite-element analyses (FEA) by comparing the FEA and analytical data
    • Covers how to design the most effective test vehicles for testing solder joints
    • Details how to design and organize, in addition to or sometimes even instead of highly accelerated life tests (HALT), highly focused and highly cost-effective failure oriented accelerated testing (FOAT) to understand the physic of failure of solder joint interconnections
    • Outlines how to convert the low cycle fatigue conditions into elastic fatigue conditions and to assess the fatigue lifetime in such cases
    • Illustrates ways to replace time- and labor-consuming, expensive, and possibly misleading temperature cycling tests with simpler and physically meaningful accelerated tests

    This book is aimed towards professionals in electronic and photonic packaging, electronic and optical materials, materials engineering, and mechanical design.
