Abstract

A method for providing an electrical connection for conductive ink includes direct writing a bus bar onto areas of a desired electrical connection of the conductive ink. The conductive ink is screen printed onto a dielectric film to create a conductive circuit. An aircraft heated floor panel includes at least one floor panel of an aircraft. The one floor panel includes a conductive circuit having a conductive ink including a bus bar directly written onto areas of a desired electrical connection of the conductive ink. The conductive ink is screen printed onto a dielectric film to create a conductive circuit.

First claim

What is claimed is:

1. A method for providing an electrical connection for conductive ink, the method comprising:
direct writing a bus bar onto areas of a desired electrical connection of the conductive ink, wherein the conductive ink is screen printed onto a dielectric film to create a conductive circuit, wherein the step of direct writing further includes forming a conformal layer of the bus bar on the conductive ink, and wherein forming the conformal layer of the bus bar on the conductive ink includes forming the conformal layer on a top surface, an edge and a side surface of the conductive ink.

2. A method as recited in claim 1 , further including soldering a wire to the bus bar to electrically connect the wire to the conductive ink.

3. A method as recited in claim 1 , wherein the conductive ink includes silver particles in an epoxy resin.

4. A method as recited in claim 1 , further including applying the conductive circuit to at least one panel skin of an aircraft floor panel.

5. A method as recited in claim 1 , wherein the bus bar is a metal bus bar.

6. A method as recited in claim 5 , wherein the metal bus bar is a copper bus bar.

7. A method as recited in claim 1 , wherein the bus bar is an alloy bus bar.

8. A heated floor panel comprising:
at least one floor panel of an aircraft including a conductive circuit having a conductive ink including a bus bar directly written onto areas of a desired electrical connection for the conductive ink, wherein the conductive ink is screen printed onto a dielectric film to create a conductive circuit, wherein the bus bar is a conformal layer of bus bar on the conductive ink that conforms to a top surface, an edge and a side surface of the conductive ink.

9. A heated floor panel as recited in claim 8 , wherein a wire is soldered onto the bus bar to electrically connect the wire and the conductive circuit.

10. A heated floor panel as recited in claim 8 , wherein the conductive ink includes silver particles in an epoxy resin.

11. A heated floor panel as recited in claim 8 , wherein the bus bar is a metal bus bar.

12. A heated floor panel as recited in claim 11 , wherein the metal bus bar is a copper bus bar.

13. A heated floor panel as recited in claim 8 , wherein the bus bar is an alloy bus bar.
