Various bonding materials have been developed for power semiconductor products. However, the fatigue characteristics of many of these materials are difficult to evaluate uniformly using a conventional test, and this difficulty represents an obstacle

The purpose of this study is to investigate the dominant factor on the fracture strength of thin film comprising of copper (Cu) helical nano-elements, which are grown by the glancing angle deposition technique. By changing the deposition angle in the

A Kriging-based method for efficiently searching materials was used to select additive elements in lead-free solders that are effective for suppressing the grain-boundary diffusion, which is the cause of smaller breaking elongation than lead-containe

The cyclic growth and recovery of warpage were observed in experiments on Si/solder/Cu layered plates subjected to cyclic thermal loading [1]. In the present study, the experiments were analyzed using representative material models for the solder and

We have developed a modified accumulated damage model that can be used to predict fatigue failure lives of solder joints in electronic devices. Our model calculates the fatigue failure life of solder on the basis of the damage that accumulates during
