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.
Claims5
A method for producing a mechano-electric transducer with strain-sensitive precision resistors which are applied to an insulating layer arranged on a carrier element comprising:
- applying the precision resistors (4) and structures of an electronic evaluation system (9) to a common insulating layer (2),
- applying at least the insulating layer (2) to a backing sheet (1A),
- covering the side of the backing sheet (1A) carrying the insulating layer (2) with a flexible film layer (6) whose adhesion to the insulating layer (2) is stronger than the adhesion of the backing sheet (1A) to the insulating layer (2),
- peeling the film layer (6) with the insulating layer (2) from the backing sheet (1A),
- applying the film layer (6) with the insulating layer (2) to the carrier element (1), and
- heat treating the carrier element for the purpose of burning out the film layer (6) and sintering on the insulating layer (2).
