Abstract: An electrically operated heating device, in particular for a heating or air conditioning system of a vehicle, is provided, comprising a heating register with a layered heating element, for converting electrical energy into heat, and two electrically insulating and heat-conducting insulating layers, which respectively make contact, at least in certain regions, with one side of the layered heating element. The insulating layers and the layered heating element are braced with one another, an abrasion-counteracting sliding layer being arranged between at least one of the insulating layers and the layered heating element. Alternatively or in addition, at least one of the insulating layers and the layered heating element have, at least in the region of their mutual contact surfaces, a material pairing with which the abrasion of the contact surfaces goes below a predetermined limit value.

Abstract: The aim of the invention is to provide a fluxing agent for soldering components, which creates one or more specific surface characteristics during the soldering process itself, thus obviating the need for the surface treatment process that is conventionally carried out after the soldering process. To achieve this, nanoparticles are added to a base substance.
