Abstract: The invention relates to a method for the production of an MID device. Proceeding from a conductor track sheet, which comprises a support sheet as well as conductor tracks arranged thereon, a plastic body is injection-molded onto this conductor track sheet. The conductor tracks have a surface having numerous microscopically small projections and depressions and are designed so as to thereby produce a positively locking connection between the conductor tracks and the plastic body.

Abstract: The invention relates to an electromechanical component which is configured as a sandwich-type structure. In the interior of said structure, a support layer consisting of foamed plastic is arranged. Said support layer is placed between covering layers which consist of compact materials. All layers are produced from hardly inflammable plastic material, for example LCP or PEI plastics so that it is not necessary to add any flame-retardant additives. The component can be configured in the shape of a slab but it can also have a more complex three-dimensional structure and can optionally be provided with mechanical functional elements. Accordingly to an aspect of the invention, the support layer of the component can consist of silicone. The composition of the inventive component provides a means for simplifying recycling a product at the end of its lifetime.
