Abstract
A wiring assembly including a flex circuit including a plastic laminate layer and a mount location configured to receive a fastener secured to a substrate. The wiring assembly further includes a flex circuit attachment feature, the flex circuit attachment feature including an extruded material bonded to the plastic laminate layer at the mount location.
Claims19
A wiring assembly, comprising:
- a flex circuit including a first surface and a second surface with a conductive layer positioned therebetween, and a plastic laminate layer and a mount location configured to receive a fastener secured to a substrate, the mount location including a through-hole;
- and
- a flex circuit attachment feature, the flex circuit attachment feature including an extruded material bonded to the plastic laminate layer at the mount location, the extruded material forming a perimeter around the through-hole, wherein the flex circuit attachment feature includes an engagement surface configured to be in direct contact with the fastener,
- wherein the flex circuit attachment feature provides a structural strength at the mount location and provides a cushion between the flex circuit and the substrate,
- wherein the fastener includes a stud having a projection that directly contacts the engagement surface of the extruded material.

A method of securing a flex circuit to a vehicle substrate, comprising:
- providing the flex circuit, the flex circuit including a plastic laminate layer, a first surface diametrically opposed to a second surface with a conductive layer positioned therebetween, and one or more mount locations;
- depositing an extruded material on the first surface of the flex circuit adjacent to the one or more mount locations;
- bonding the extruded material to the plastic laminate layer;
- and
- providing a fastener at the one or more mount locations,
- wherein the fastener is configured to secure the flex circuit to the vehicle substrate,
- wherein the extruded material forms an engagement surface, wherein the fastener is configured to be in direct contact with the engagement surface, and
- wherein the fastener includes a stud having a projection that directly contacts the engagement surface of the extruded material.
