Abstract: An electronics unit includes a low multi-point metallic mount on which an insulating layer is arranged. A conductor track system is arranged on the insulating layer and electronic power components are arranged on the conductor track system. The insulating layer is a sintered electrically insulating polymer layer on which the conductor track system, which comprises a sintered glass frit with a noble metal filling, is arranged.

Abstract: In a device for measuring the axle load of a motor vehicle, at least one extension-sensitive resistor is arranged on at least one component of a motor vehicle which is subject to a change in shape as a function of the load, with at least one insulating layer being arranged in between.

Abstract: A pressure sensor includes a membrane having a radially peripheral edge region fixedly arranged on a support. One side of the membrane can be acted on by a medium being measured and the membrane can be deflected in response to pressure of the medium. Measuring elements and an electric circuit interconnecting the measuring elements are arranged on the membrane, the measuring elements and the circuit being applied by the thick-film technique and sintered on in a thermal process. The membrane is made of an electrically conducting metal and bears an insulating layer, on which the measuring elements and the electric circuit are arranged. In this case, the insulating layer consists of a material having a coefficient of expansion that lies between the coefficient of expansion of the metal of the membrane and the coefficient of expansion of the material of the measuring elements and the electric circuit.

Abstract: An electrical circuit having at least one electrical component, in particular a strain-sensitive resistor and conductor tracks which are applied to a metallic carrier with the intermediate positioning of at least one insulating layer, at least one further conductor track, which is connected to at least one conductor track of the circuit, is applied to the surface of the metallic carrier. The invention also relates to methods for manufacturing the electrical circuit.

Abstract: The invention relates to a mechanical-electrical transducer having a bridge circuit formed on an insulation layer through an electrical interconnection of expansion-sensitive thick-film resistors by means of conductor tracks. The insulation layer is arranged directly on a metallic component that is to be mechanically loaded, and being intimately connected to said component by means of a thermal process. In this case, in the event of mechanical stressing of the component, an electrical signal corresponding to the expansion of the thick-film resistors can be tapped off. In order that the mechanical-electrical transducer exhibits a small electrical offset in the output signal in the event of mechanical loading, the metallic component to be loaded comprises a thermally post-hardening metal or a thermally post-hardening metal alloy.

Abstract: A method for producing an electric resistor, in particular a resistance strain gauge, in which an insulating layer and a resistive layer are sequentially applied to a carrier element. The insulating layer or the resistive layer is applied to a backing sheet, the side of the backing sheet carrying the insulating or resistive layer being covered with a flexible film layer whose adhesion to the insulating layer or resistive layer is stronger than the adhesion of the backing sheet to the insulating layer or resistive layer. The film layer with the insulating or resistive layer is peeled off of the adhesive backing sheet and applied to a carrier element, which is heated to burn off the film layer and sinter on the insulating or resistive layer.
