Abstract: A method of fabricating a flexible film is provided. The method includes opening an imide ring on a polyimide film; applying a catalyst to the polyimide film; removing tin from the catalyst; forming a first metal film on the polyimide film; drying the polyimide film having the first metal film at a temperature of 110-200° C.; and forming a second metal film on the first metal film. According to the method, it is possible to fabricate a flexible film without a requirement of an adhesive layer and thus provide a flexible film with excellent physical properties such as excellent plating properties, high adhesive strength, high heat resistance, high drug resistance, excellent migration properties and high folding endurance.

Abstract: A device for transferring a film is provided. The device includes a roller transferring a film; a balancing unit connected to the roller by fixed supporters, the fixed supporters being disposed on both sides of the roller; and springs disposed on both sides of the balancing unit, wherein, if the film is out of balance, the balancing unit restores balance to the film by vibrating the both sides of the balancing unit. That is, if a film becomes out of balance during the transfer of the film, the device may restore balance to the film with the aid of the balancing unit which can vibrate on both sides of the balancing unit due to the springs.

Abstract: A device for fabricating a flexible film is provided. The device includes a serving unit providing an insulation film; a main processing unit including at least one of a dust removing unit, an etching unit, a neutralizing unit, a coupling unit, a catalyst bonding unit, a plating unit, and a drying unit; an assistant power unit controlling a tension of the insulation film; a top transporter disposed at an upper part of the main processing unit; and a bottom transporter disposed at a lower part of the main processing unit, wherein the top transporter includes a squeezing unit pressing a material on the insulation film. The device can improve the quality of a flexible film by pressing the flexible film using the squeezing unit.

Abstract: A metal film-plating system including an unwinding process part configured to provide a film, a degreasing process part configured to remove impurities from the film, an etching process part configured to perform an etching process on the film, a neutralizing process part configured to perform a neutralizing process on the film, a coupling process part configured to couple the neutralized film with a coupling agent, a catalyst-adding process part configured to adsorb a catalyst onto the coupled film, an underplating process part configured to perform an underplating process on the film, and a plating process part configured to perform a plating process on the film. Further, at least one of the unwinding process part, the degreasing process part, the etching process part, the neutralizing process part, the coupling process part, the catalyst-adding process part, the underplating process part, and the plating process part includes a wetting apparatus configured to perform a wetting operation.
