For electrically conductive adhesives (ECAs) interconnection, adequate electrical, mechanical and thermal performance are crucial for long-term service reliability. The work focused primarily on analyzing the effects of environmental aging on the reliability and failure mechanism of ECAs joints. In this paper, high temperature and humidity (85 degrees C, 85%RH, 1000 h), thermal shock (-40 degrees C to 125 degrees C, 1000 cycles) and thermal aging (125 degrees C, 1000 h) tests were performed to study the reliability of the ECAs. Additionally, the fracture modes were investigated by mechanical shear strength testing before and after the reliability tests. The interfacial microstructure of the ECAs was investigated and the fracture mechanism of ECAs was characterized. The study showed that the reliability of the ECAs was improved compared with conventional ECA1 and ECA2.
