摘要
The present invention relates to a process for producing a semi-additive soft copper film laminated film using a carbide-free polyimide film and a semi-additive soft copper film laminate film produced therefrom. The present invention relates to a process for producing a semi-additive flexible copper foil laminated film by sputtering and electroplating, which comprises adhering an adhesive protective film to the back surface of a thin carbide polyimide film, It is possible to process a semi-additive soft copper film laminated film to which a hard protective polyimide film having a thickness of 20 탆 or less is applied.
