Abstract
In this study, the Cu joint with a new high Tg epoxy resin was used as the research object. Tensile test, fracture surface observation and XPS analysis for fracture surface were performed using Cu/resin joints after high temperature and high humidity aging treatment under different conditions. The effect of aging on the adhesion strength and fracture mode of the Cu/resin joint was investigated. The analyzed results indicated that the adhesion strength of Cu/resin joint decreased with an increase in the aging time and aging temperature. Fracture mainly occurred at the Cu/resin and partially occurred at the Cu oxide formed in the surface of Cu.
