Claims19
A circuit board comprising:
- a circuit carrier;
- a cover layer composed of a nonconductive material, comprising an organic substance, arranged on the circuit carrier;
- and
- a first metallization layer at least partly arranged on the cover layer,
- wherein the first metallization layer has a flexible region.
2 more elements
A method for producing a circuit board, comprising the steps of:
- providing a circuit carrier;
- applying a delamination layer to a spatially delimited partial region of the circuit carrier;
- applying a layer sequence to the delamination layer and a partial region of the circuit carrier, comprising
- a cover layer, comprising an organic material, and
- a first metallization layer on the cover layer;
- and
- structuring the cover layer and the first metallization layer
- wherein a flexible region of the first metallization layer is defined.
5 more elements
A method for producing a circuit board, comprising the steps of:
- providing a circuit carrier;
- working a recess in the circuit carrier;
- applying a layer sequence to the circuit carrier, such that the recess is covered but not filled, as a result of which a free space is formed, wherein the layer sequence comprises a cover layer, comprising an organic material, and a first metallization layer on the cover layer;
- and,
- structuring the cover layer and the first metallization layer above the free space, such that a flexible region of the first metallization layer is formed.
