Research Abstract |
In recent years, operating condition of electronic devices is becoming increasingly severe due to the temperature raise with high density mounting of electronic devices. Solder connections in electronic devices are a key part for the quality assurance of electronic devices and the quality assurance of solder connection is strongly needed. Therefor, development of an accurate and efficient fatigue life estimation method applicable to solders is needed for the quality assurance of solder connections. In this study, a fatigue life estimation method for Sn-3.5Ag solder was developed based on the results of fatigue test using Sn-3.5Ag solder.
