电解铜箔、包含该箔的电子组件和电池;ELECTROLYTIC COPPER FOIL, ELECTRIC COMPONENT AND BATTERY COMPRISING THE FOIL

摘要

本发明提供一种电解铜箔，其中沈积侧边之中心线平均粗糙度Ra、最大高度Rmax及十点平均高度Rz满足以下等式：根据本发明之所述电解铜箔具有维持低剖面及高强度之高伸长率，且特定言之，具有高光泽度，且因此可用于中-大尺度锂离子二次电池之集电器及用于卷带承载封装(tape carrier package；TCP)之卷带式自动接合(tape automated bonding；TAB)的半导体封装。;The electrolytic copper foil according to the present invention has a high elongation maintaining a low profile and a high strength, and particularly, has a high gloss, and thus may be used a current collector of medium-large scaled lithium ion secondary battery and a semiconductor packaging for tape automated bonding (TAB) which is used in tape carrier package (TCP).
