Abstract: The present invention relates to a layered material and a method of producing the same. The layered material has one or more layers, including at least one foamed layer, said foamed layer comprising a first polymer and a second polymer, said foamed layer having a high BBC.

Abstract: Method for producing a plastic layer having a layer thickness of less than 200 ?m on an upper side of a substrate includes the following steps: applying plastic powder to the substrate upper side by means of a powder scattering device, then cleaning the substrate underside, then melting the applied plastic powder in a furnace, as a result of which the plastic layer is formed on the substrate, and cooling the substrate, wherein the substrate is transported continuously from method step to method step.

Abstract: Disclosed are composite build-up materials for the manufacture of printed circuit boards, IC substrates, chip packages and the like. The composite build-up materials are suitable for embedding circuitry such as microvias, trenches and pads. The composite build-up materials comprise a carrier layer (1), a resin layer without reinforcement (2), and a resin layer with reinforcement (3). The circuitry (9) is embedded into the resin layer without reinforcement (2).

Abstract: Disclosed is a process for mixing and gentle transport and transfer of powders to substrates.

Abstract: The invention relates to a process for the mixing and gentle transport and the transfer of powders to substrates wherein the powder particles are first charged by friction in the presence of magnetic particles and then transported by means of a fluidized bed and optionally one or more mixing rolls and then transferred and applied to a substrate by means of an electric field between a brush drum and a substrate drum carrying said substrate, characterized in that the mixing and the transport of the powder particles and the magnetic particles are carried out by means of a boiling bed.
