Manufacturing Process Effect on Fatigue Properties for Copper Thin Film
- 발행 : 2007.05.30
초록
The copper film coated by Sn is often used in various applications such as LCD, Mobile Phone and etc. Especially, when the film is used as tape carrier package(TCP) of LCD panel, the film is repeatedly applied by mechanical or(and) thermal stress and then is often failed. Therefore, to guarantee the reliability of the electrical devices using the film, the tensile and fatigue characteristics of the film are important. In this study, to obtain the tensile and fatigue characteristics of the film, the specimen was fabricated by etching process to make a smooth specimen of 2000
