Effect Of Humidity Cycling On Reliability Of Overlaid High Density Interconnects
X. Shan, R. Agarwal, M. Pecht, and J. Evans
This paper presents a finite element simulation, performed to observe
the stresses generated in a typical HDI structure as a result of "swelling"
mismatches due to water absorption. The focus is on potential stress
concentration sites in the polyimide layer.
