Abstract

Trends in microelectronics packages such as low cost, miniaturization, high performance, and high reliability made area array interconnecting technologies including flip chip, CSP (Chip Scale Package) and BGA (Ball Grid Array) mainstream technologies. Underfill technology is used for the reliability of the area array technologies, thus electronics packaging industry regards it as very important technology In this paper, the underfill technology is reviewed and the recent advances in the underfill technology including new processes and materials are introduced. These includes reworkable underfills, no-flow underfills, molded underfills and wafer - level - applied underfills.
