Nondestructive characterization of the mechanical strength of diffusion bonds. I. Experimental results

The application of ultrasonic reflectivity for the characterization of a variety of Cu diffusion bonds is described. The quality of each diffusion bond has been described by its ultimate tensile strength. Furthermore, fractography of the failed bonds provided information on the relative fraction of...

Zusammenfassung:The application of ultrasonic reflectivity for the characterization of a variety of Cu diffusion bonds is described. The quality of each diffusion bond has been described by its ultimate tensile strength. Furthermore, fractography of the failed bonds provided information on the relative fraction of bonded areas and the geometry of the bonds. The experimental results obtained and empirical correlations between the quantities determined are presented. Graphs, photomicrographs. 23 ref.--AA
