粗糙化处理铜箔、覆铜层叠板和印刷电路板
摘要：
本发明提供能够显著地提高与绝缘树脂的密合性和可靠性(例如吸湿耐热性)的粗糙化处理铜箔。本发明的粗糙化处理铜箔在至少一侧具有具备由针状结晶构成的微细凹凸的粗糙化处理面，针状结晶的表面全部由Cu金属和Cu2O的混相构成。
摘要（英）：

There is provided a roughened copper foil which can significantly improve adhesion to an insulating resin and reliability (e.g., hygroscopic heat resistance). The roughened copper foil of the present invention has at least one roughened surface having fine irregularities composed of acicular crystals, wherein the entire surface of the acicular crystals is composed of a mixed phase of Cu metal and Cu2O.
