Abstract

Electrical components may have plastic packages. Contacts may be formed on exterior surfaces of the plastic packages. A plastic package for an electrical component may have an elongated shape that extends along a longitudinal axis. A first groove may run parallel to the longitudinal axis on a lower surface of the plastic package. A second groove may run perpendicular to the first groove on an opposing upper surface of the plastic package. The electrical components may be coupled to fibers in a fabric such as a woven fabric. A first solder connection may be formed between the first groove and a first fiber such as a weft fiber. A second solder connection may be formed between the second groove and a second fiber such as a warp fiber.

First claim

What is claimed is:

1. A fabric-based item, comprising:
a woven fabric formed from interwoven fibers, wherein the interwoven fibers include a first set of fibers that extend in a first direction and a second set of fibers that extend in a second direction; and
an electrical component having first and second opposing surfaces and having first and second contacts on the first surface, wherein a first fiber of the first set of fibers is coupled to the first contact in a first fiber guiding structure and a second fiber of the first set of fibers is coupled to the second contact in a second fiber guiding structure and wherein a third fiber of the first set of fibers lies between the first and second fibers of the first set of fibers and contacts the second surface of the electrical component.

2. The fabric-based item defined in claim 1 wherein the first and second fibers of the first set of fibers are conductive fibers.

3. The fabric-based item defined in claim 2 wherein the conductive fibers comprise a conductive coating on a non-conductive core.

4. The fabric-based item defined in claim 3 wherein the conductive fibers comprise a locally stripped insulating coating.

5. The fabric-based item defined in claim 2 wherein the third fiber of the first set of fibers is one of at least three insulating fibers of the first set of fibers that lie between the first and second fibers and that each overlap the electrical component.

6. The fabric-based item defined in claim 1 wherein the electrical component comprises a light-emitting diode.

7. The fabric-based item defined in claim 1 wherein the electrical component comprises a sensor.

8. The fabric-based item defined in claim 1 wherein the first and second directions are orthogonal.

9. A fabric-based item, comprising:
a woven fabric, wherein the woven fabric comprises interwoven insulating strands and conductive strands; and
an electrical component having first and second opposing surfaces and having first and second parallel grooves in the first surface, wherein a conductive strand in the conductive strands is electrically connected to the electrical component in the first groove and wherein an insulating strand in the insulating strands is in contact with the second opposing surface.

10. The fabric-based item defined in claim 9 wherein the conductive strand is parallel to the insulating strand.

11. The fabric-based item defined in claim 10 further comprising:
an additional conductive strand that is electrically connected to the electrical component in the second groove.

12. The fabric-based item defined in claim 11 further comprising:
an additional insulating strand that is orthogonal to the insulating strand, wherein the insulating strand is interposed between the additional insulating strand and the electrical component.

13. The fabric-based item defined in claim 12 wherein the first and second grooves have curved sides.

14. The fabric-based item defined in claim 9 wherein the electrical component comprises an electrical device enclosed in a plastic package, and wherein the first and second grooves are formed in the plastic package.

15. The fabric-based item defined in claim 14 further comprising:
metal traces that extend through the plastic package and couple terminals of the electrical device to respective contacts in the first and second grooves.

16. The fabric-based item defined in claim 15 further comprising:
conductive shield structures that shield the electrical device.

17. The fabric-based item defined in claim 14 , wherein the plastic package is elongated and extends along a longitudinal axis and wherein the first and second grooves are orthogonal to the longitudinal axis.

18. A fabric-based item, comprising:
a fabric formed from intertwined fibers that include first, second, and third parallel fibers, wherein the third fiber is interposed between the first and second fibers; and
an array of electrical components, each having first and second opposing surfaces, wherein each electrical component has first and second parallel grooves in the first surface, wherein a contact in the first groove is electrically coupled to the first fiber, wherein the second groove is coupled to the second fiber, and wherein the electrical component is interposed between the first fiber and the third fiber.

19. The fabric-based item defined in claim 18 wherein the array of electrical components forms a touch sensor array.

20. The fabric-based item defined in claim 18 wherein each electrical component in the array of electrical components comprises a light emitting diode and each electrical component in the array of electrical components operates as a pixel in a display.
