Abstract
Eutectic Au-20Sn(compositions are all in weight percent unless specified otherwise) solder alloys were soldered on the Ni substrate with various time and temperature. The composition, phase identification and morphology of intermetallic compounds(IMC) at the interface were examined using Scanning Electron Microscopy(SEM). There were two types of IMCs,
공정 Au-20Sn 솔더합금을 솔더링 시간과 온도를 달리하여 Ni위에서 솔더링하였다. 주사전자현미경 (SEM)을 사용하여 계면에 생성된 IMC의 조성, 상, 모양에 대해 조사하였다. 계면에는
