The Mechanisms Analysis of the ACF Bonding Strengths after the High Temperature/Humidity Environment Test

摘要

The environmental experiments of the thermal cycling (-40 ～ 125℃) and the high temperature/humidity (85℃, 85%RH) aging were used to evaluate the reliability of the specimens bonded with ACFs. It was found that the high temperature/humidity was the harshest condition to the ACFs bonding. The DSC testing and interfacial stresses analysis has been done under the high temperature/humidity condition. The mechanisms of the bonding strength decrease were investigated.
