Abstract: With the rapid development of high-power electronic technology, the operating temperature of chips continues to rise. Sintered micro- and nano-silver, due to their excellent conductivity, thermal conductivity, and mechanical strength, have become one of the most promising high-temperature packaging interconnect materials. However, the reliability of sintered silver joints under long-term high-temperature environments and frequent switching conditions has not been fully validated. By reviewing the reliability research on sintered silver joints in high-temperature aging, thermal cycling, thermal shock and power cycling tests, the material and process reliability of low-temperature silver sintering technology is systematically summarized, and the two key mechanisms leading to joint degradation are deeply analyzed: the thermal driving force effect and thermal stress impact. Through analysis, the current key technical challenges are summarized, and effective strategies to improve the reliability of sintered silver joints are explored.

Key words: sintered silver, metallization, aging, thermal stress, reliability
