Abstract
A sensor component comprises a ceramic support (12) with a metal film (14) applied thereto. At least one connecting wire (16) is electrically connected to the metal film (14) in a contact area (18). A fixing glaze (20) is applied to the metal film (14) and the at least one connecting wire (16) in the contact area (18). The ceramic support (12) has at least one recess (24) in the area of the fixing glaze (20).
Claims18
A sensor component comprising
- a planar ceramic support having a surface;
- a metal film applied to said ceramic support, the metal film having two connection ends on the surface;
- two connecting wires electrically connected to the metal film at a respective connection end in a contact area, and the two connection wires being positioned on top of the respective connection ends to achieve the electrical connection;
- and
- a non-conductive fixing glaze applied to the ceramic support, the metal film and the at least one connecting wire in the contact area;
- wherein the ceramic support has at least one recess in the contact area, the recess extending from the surface of the support into the support, the recess being filled with a glass composition or the non-conductive fixing glaze so that the mechanical interlocking between the fixing glaze and the ceramic support is improved by said at least one recess.

A method of producing a sensor component comprising the steps of:
- applying a metal film to a surface of a planar ceramic support, the metal film having two connection ends;
- providing at least one recess in said ceramic support, the recess extending from the surface of the support into the support;
- positioning two connecting wires on top of a respective connection end of the metal film thereby electrically connecting the two connecting wires with the metal film at the respective connection end in a contact area;
- filling the recess with a non-conductive fixing glaze composition or a glass composition;
- applying the non-conductive fixing glaze composition to the connecting wire, the metal film and the at least one recess in the contact area;
- and
- fusing the non-conductive fixing glaze composition to the ceramic support, whereby due to the recess the mechanical interlocking between the fixing glaze and the ceramic support is improved.

A sensor component comprising:
- a ceramic support;
- a metal film applied to said ceramic support;
- at least one connecting wire electrically connected to the metal film in a contact area;
- and
- a non-conductive fixing glaze applied to the metal film and the at least one connecting wire in the contact area;
- wherein the ceramic support has at least one recess in the area of the non-conductive fixing glaze, and
- wherein the cross-section of the at least one connecting wire widens within the non-conductive fixing glaze in the connecting wire direction facing the ceramic support.

A method of producing a sensor component comprising the steps of:
- applying a metal film to a ceramic support;
- producing a comblike structure of the metal film by laser irradiation or plasma etching;
- providing at least one recess in said ceramic support by sawing said recesses into the ceramic support material;
- electrically connecting the metal film to at least one connecting wire in a contact area;
- applying a non-conductive fixing glaze composition to the connecting wire, the metal film and the at least one recess in the contact area;
- and
- fusing the non-conductive fixing glaze composition to the ceramic support.
