초록
Kirkendall void는 전해도금 Cu/Sn-Ag 솔더 접합부에서 형성되었으며 Cu 도금욕에 함유되는 첨가제에 의존한다. 첨가제로 사용된 SPS의 함량의 증가와 함께
A noticeable amount of Kirkendall voids formed at the Sn-3.5Ag solder joint with electroplated Cu, and that became even more significant when an additive was added to Cu electroplating bath. With SPS, a large amount of voids formed at the
