Abstract:Lead-free solders are applied under special conditions with the improvement of property of the solders and people''''s awareness of environmental protection. The research status and development trend of lead-free solders used under special conditions were reviewed synthetically. First of all, the failure mechanism of solder joints under different special conditions was discussed. Moreover, the ways to enhance the reliability of lead-free solders under several special conditions were reported and analyzed, such as microalloying, particle strength and substrate improvement. In addition, the defects of the current reliability research of lead-free solders were summarized, and the further research was prospected.

 

Key words: special condition; lead-free solder; microalloying; particle strength; substrate improvement; reliability
