  • Patent number: 7678242
    Abstract: Disclosed is a system and a method for manufacturing flexible copper clad laminate film capable of efficiently electroplating both surfaces of a polyimide-based film to form copper plating layers thereon while making it easy to repair and maintain the apparatus or clean its plating or cleaning bath. The system includes a pickling device adapted to spray a pickling liquid to both surfaces of a to-be-plated film to remove oxide coatings from the copper coatings; a number of water-cleaning devices for removing the pickling liquid and copper electrolyte remaining on the film; at least one plating device positioned between the water-cleaning devices to form copper plating layers on both surfaces of the film; an antirust device for preventing the copper plating layers, which have been formed by the plating device, from rusting; and a drying device for drying the antirust liquid on the film, which has been subjected to antirust treatment.
