  • Abstract
    Stress-strain oscillation occurred prior to the appearance of necking deformation in tensile tests of polyimide films. This oscillation appears to be related to initiation and propagation of craze, rather than neck deformation. Both temperature and strain rate have a significant affect on oscillation. The effects of craze initiation and propagation on reliability of high density interconnects are discussed
