Abstract
In an apparatus for removing protective films, a groove is formed in a roller having an adhesive surface sufficient to peel off a protective film from a printed wiring board. The exposed printed wiring board, on which a dry film provided with a protective film is applied, is passed between the rollers. Thus, the protective film is peeled off from the surface of the dry film resist of the printed wiring board and adhered to the roller so as to be removed. As a result, the protective film can be removed at a high speed, and automated removal of protective films can be achieved.
Claims21
An apparatus for removing protective films, the apparatus comprising:
- a roller member provided with at least one peripheral groove, said roller member having an adhesive outer surface for removing a protective film from a printed wiring board and adhering the film to said adhesive outer surface;
- a separator, a portion of which is disposed within said groove, for separating the protective film from said adhesive outer surface of said roller member as said roller member is rotated;
- and
- cleaning means for cleaning said adhesive outer surface of said roller member.
An apparatus for removing protective films, the apparatus comprising:
- a plurality of roller members each provided with at least one groove and having an adhesive outer surface for removing a protective film from a printed wiring board and adhering the film to said adhesive outer surface;
- a separator engaged with each said roller member and having a portion extending into said at least one groove, with each said separator separating protective films from said adhesive outer surface of one of said roller members as said roller members are rotated;
- and
- cleaning means for cleaning said adhesive outer surface of said roller member.
An apparatus for removing a film layer, the apparatus comprising:
- a roller member provided with at least one peripheral groove, said roller member having an adhesive outer surface for removing a film layer from a surface and adhering the film layer to said adhesive outer surface;
- a separator, a portion of which is disposed within said groove, for separating the film layer from said adhesive outer surface of said roller member as said roller member is rotated;
- and
- cleaning means for cleaning said adhesive outer surface of said roller member.
