The present invention relates to a method for encapsulating an electronic arrangement against permeants, in which a pressure-sensitive adhesive composition based on vinylaromatic block copolymers is provided, and in which the pressure-sensitive adhesive composition is applied onto and/or around the regions of the electronic arrangement which are to be encapsulated.

Method for encapsulating an electronic arrangement

The invention relates to a method for the production of a layered or stacked inorganic/organic composite material, a predominantly inorganic material being provided and a polymer material being provided, characterized in that the predominantly inorganic material has a glass transition temperature or melting temperature lower than 500&#xb0; C., that the predominantly inorganic material and the polymer material are each molten, and that the predominantly inorganic material and the polymer material are coextruded from the melt and thus form the composite material.

Method for the production of a layered or stacked inorganic/organic composite material

A heat conduction composition is proposed, comprising at least one polymer and a heat-conducting auxiliary material that has an especially high heat conductivity and at the same time has a high mechanical strength. To this end, the heat-conducting auxiliary material comprises particles that in turn are made up of primary particles and that have a mass-specific surface area of 1.3 m/g or less. Also described are a heat-conducting surface element manufactured from said heat conduction composition as well as application possibilities thereof.

Heat conduction composition

A method glues a heat-activated glueable surface element to an adhesive substrate which does not conduct electric current, whereby a surface thereof has only a low thermal conductivity. The heat-activated glueable surface element has an electrically conductive layer in addition to a heat-activated adhesive mass. The layer is inductively heated for a short time in an alternating magnetic field at a frequency from a middle frequency range. A high pressure of at least 1 MPa is exerted on the gluing surface simultaneously to the inductive heating, whereby preventing thermal decomposition reactions is possible. Further, a device performs the method and has an induction heater integrated in a press tool.
