Abstract
Electronic packaging is a field in rapid evolution due to strong and competing customer demands for increased functionality and performance, further miniaturization, heightened reliability, and lower costs. Such product drivers cause a myriad of reliability challenges for the engineer involved in the mechanical design of electronic systems, and several methods of experimental mechanics have become critical tools for the design and development of electronic products. In this chapter, we present an overview of important experimental mechanics applications to electronic packaging. Mechanics and reliability issues for modern electronic systems are reviewed, and the challenges facing the experimentalist in the packaging field are discussed. Finally, we review the state of the art in measurement technology, with the presentation of selected key applications of experimental solid mechanics to the electronic packaging field. These important applications are grouped by the goal of the measurement being made, including delamination detection, silicon stress characterization, evaluation of solder joint deformations and strains, warpage measurements, evaluation of behavior under transient loading, and material characterization. For each application, the important experimental techniques are discussed and sample results are provided.
