<p>The invention relates to a method for joining copper films of any particular type and thickness to aluminium metal sheets of any particular type of alloy and thickness in order to simplify assembly of multilayer press packets. The copper films are placed upon both sides of the aluminium metal sheet. Said copper films are larger than the metal sheet. The films are connected in material fit outside the useful surface, leaving a free space for thermal expansion of the sheet metal. Simultaneously, positioning holes are created for the multiplaten press. The copper films are selected in such a way that they are larger than the aluminium metal sheet. When the aluminium metal sheets are re-clamped with the copper film and placed in the multiplaten press together with epoxy resin fabric for multilayer pressing, the aluminium can expand in an unrestricted manner during heating without causing surface tensions to occur on the copper film. As soon as the epoxy resin dissolves, it can flow along the salient copper film without coming into contact with the aluminium metal sheet and covering the multilayer with adhesive. The salient edge of the copper provided with adhesive can then be easily separated along the aluminium sheet.</p> |
