Abstract:
1. A metal film-plating system, comprising: an unwinding apparatus configured to provide a film; a degreasing apparatus configured to remove impurities from the film; an etching apparatus configured to perform an etching process on the film; a neutralizing apparatus configured to perform a neutralizing process on the film; a coupling apparatus configured to couple the film with a coupling agent; a catalyst-adding apparatus configured to adsorb a catalyst onto the film; an underplating apparatus configured to perform an underplating process on the film; and a plating apparatus configured to perform a plating process on the film, wherein at least one of the unwinding apparatus, the degreasing apparatus, the etching apparatus, the neutralizing apparatus, the coupling apparatus, the catalyst-adding apparatus, the underplating apparatus, and the plating apparatus, includes a wetting apparatus configured to perform a wetting operation, wherein the unwinding apparatus is further configured to unwind the film from a predetermined backing, and wherein the unwinding apparatus comprises: a rectangular parallelepiped housing frame; a substrate roll-mounting stand having a release paper-recovering roller and a substrate roller detachably mounted at an upper and a lower position of the substrate roll-mounting stand; a table having a supply-guiding roller, an end-connecting unit, and a diverting roller formed at an upper position of the table; a driving motor configured to rotate the substrate roller; and a tension controlling assembly configured to control a tension of the film.
