Abstract

In recent years, because of the expansion of the digital consumer electronics market and automotive electronics, demand for personal computers and mobile phones is increasing. Copper alloys are used as the lead frame members mounted on the IC chip of the electronic device. In this study, we attempted the production of copper alloy sheet by using a vertical twin roll caster. As a consequence, we have achieved the production of Cu-Sn-P and Cu-Ni-Si alloy thin plate by using vertical twin roll casting.
