摘要
We are conducting the advanced development of a sintering Cu paste (with/without pressure type) for use in power devices. For this report, we carried out a power cycle test and its Weibull analysis using sintering Cu as a bonding material and compared the results to the power cycle lives of Sintering Ag and high-lead solder. The characteristic life for sintering Cu without pressure was about 14 times higher than that of high lead solder when the power cycle condition was T j max = 175°C and ΔT j = 100°C, and about 40 times higher for sintering Cu with pressure. Therefore, the sintering Cu has a superior bonding reliability compared with sintering Ag and high lead solder. Copyright© The Japan Institute of Electronics Packaging.
