    • 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.

    • An improved process for producing a consolidated polymeric monolith from an assembly (10) of thermoplastic polymer. The assembly (10) is placed under pressure to fill a majority of the voids thereof by mechanical deformation of the fibers, and heated to a temperature too low to melt the fibers at the deformation pressure but sufficiently high to at least partly melt the fibers at a lower transition pressure. The asembly (10) is compressed in a vacuum press mold (12), between a piston (14) and a matrix (16) and during compression, vacuum is applied to ports (18a, 18b, 18c, and 18d) in matrix (16). While maintaining the assembly (10) at this temperature, the pressure is reduced to the transition pressure long enough for partial melting of the fibers to fill the rest of the voids, and then is increased to a consolidation pressure at least as high as the deformation pressure. The process allows accurate control of thermal expansion coefficients of the product.

    • Known methods exist for producing the required substrate materials for electric circuit carriers, whereby metal coatings are applied to a dielectric substrate using a glow-discharge method and other metal coatings are applied using an electroplating method. These methods are, however, not suitable for the production of substrate materials that can be used for high frequency applications in the giga hertz range. The invention builds upon the previously cited methods and solves the problem linked thereto by using fluoropolymers and by coating these materials with nickel in a glow-discharge method, whereby very flat surfaces of the substrate can also be given an adhesive coating. The metallized materials can be covered with other metal coatings from electroless or electrolytic separation baths.
