Abstract
A device comprises a substrate and a stacked bond ball structure. The substrate comprises a bond pad, and the stacked bond ball structure comprises a first and a second bond ball. The first bond ball is in contact with the bond pad, and the second bond ball is positioned on the first bond ball. The stacked bond ball structure is configured to be coupled to a resistance-sensing circuit, such that a resistance of an interface between the first bond ball and the bond pad can be measured to determine an amount of degradation of the interface between the first bond ball and the bond pad. In some implementations, the device further comprises a controller configured to obtain a measured resistance of the interface from the resistance-sensing circuit and determine the amount of degradation of the interface based at least in part on the measured resistance.
