摘要: 
Sn/Ag/Cu tri-layer structure was frequently encountered in microelectronic solder joints. In flexible microelectronics, the Sn/Ag/Cu tri-layer structure was usually subjected to strain when the plastic substrate was deformed. This study investigated the Sn/Ag/Cu interfacial reactions on a polyimide substrate subjected to compressive and tensile strain. Under both strain conditions, the Sn/Ag/Cu tri-layer structure was replaced by the multi-layer structure of Sn/Ag(3)Sn/Cu(6)Sns/Cu(3)Sn/Cu after 150 and 200 degrees C of aging. However, blocky Cu(6)Sn(5) was formed at the Sn/Ag(3)Sn interface subjected to compressive strain but rarely observed at that subjected to tensile strain, revealing that strain was an influential factor to the Sn/Ag/Cu interfacial reactions.
