<p>Disclosed herein is a release film for PCB lamination processes, which is obtained by laminating a layer B, consisting of polypropylene (PP) resin, on one side of a layer A, consisting of either a film made of any one selected from the group consisting of polycarbonate (PC) resin, polybutylene terephthalate (PBT) resin, a mixed resin of polycarbonate (PC) and polybutylene terephthalate (PBT), a mixed resin of polycarbonate (PC) and polyethylene terephthalate (PET), a mixed resin of polybutylene terephthalate (PBT) and polyethylene terephthalate (PET), and a mixed resin of polycarbonate (PC), polybutylene terephthalate (PBT) and polyethylene terephthalate (PET), or a film made of polyethylene terephthalate (PET). The disclosed release film resists pressing process conditions of high temperature and high pressure and, at the same time, has excellent releasability from a polyimide film as a cover layer, and does not substantially transfer a material to PCB or the cover layer.</p> |
