Abstract:
A film applying apparatus comprising:a substrate conveying device for conveying a plurality of substrates along the substrate conveying plane at intervals in sequence;a film guide means for guiding a laminated film constituted by lamination of at least a photosensitive resin layer onto a light-transmissible support film and having width nearly equal to the substrate width, towards the substrate in the state that the photosensitive resin layer being exposed is directed to one surface of the substrate being conveyed; anda pair of laminating rolls with the touch length being 700 mm or more and having an elastic material laminated on the outer circumference and being heated and rotated, for performing thermal pressure bonding of the laminated film and the substrate at the thermal pressure bonding temperature, while the laminated film and the substrate are grasped and sent,wherein a pair of preparatory bonding rolls having an elastic material laminated on the outer circumference and rotating are installed at the upstream side of the laminating rolls, for press-bonding the laminated film and the substrate at a lower temperature than the thermal pressure bonding temperature and performing the preparatory bonding, while the laminated film and the substrate are grasped and sent, andthe diameter in the preparatory bonding rolls at the side of press-bonding the laminated film to the substrate and the pushing-down force at grasping the laminated film and the substrate are specified so that the range of the elastic deformation into a plane shape at contacting with the substrate via the film on the roll surface becomes 5 mm or less in the substrate conveying direction.
