Abstract

A method of manufacturing a portion of a portable electronic device includes forming a fibrous laminate sheet to provide a laminate body, and connecting a rim with the body. The rim includes a connector for coupling with a complementary part.

Claims (31)

1. A method of manufacturing a portion of a portable electronic device, the method comprising:

providing a fibrous laminate sheet;

applying a coating to the fibrous laminate sheet, the coating having a material and a thickness such that the coating does not substantially interfere with radio frequency (RF) functions of the portable electronic device, wherein the coating comprises a non-conductive vacuum metalized (NCVM) coating;

shaping the fibrous laminate sheet to form a shaped fibrous laminate body; and

connecting a rim to the shaped fibrous laminate body without molding the rim on the shaped fibrous laminate body, the rim including a connector for coupling with a complementary part of the portable electronic device,

wherein the shaped fibrous laminate body comprises:

a substantially flat portion having four edges;

a projection extending substantially perpendicularly away from the substantially flat portion and adjoining each of the four edges at a curvature; and

an antenna embedded in the fibrous laminate body, wherein the antenna is formed as a sheet antenna of metallic material configured to couple to a communication subsystem of the portable electronic device, and wherein the fibrous laminate body comprises at least one or more of glass fiber, carbon fiber and nylon.

2. The method according to claim 1 , wherein shaping the fibrous laminate sheet comprises heating and/or compression forming.

3. The method according to claim 1 , wherein the connecting comprises at least one or more of adhering the rim to the projection of the body and affixing the rim to the projection of the body.

4. The method according to claim 1 , further comprising cutting the fibrous laminate body prior to the connecting.

5. The method according to claim 1 , wherein the portion of the portable electronic device comprises a back portion.

6. The method according to claim 5 , wherein the back portion of the portable electronic device comprises a battery cover.

7. The method according to claim 1 , wherein the providing comprises:

dying or coating woven fabric; and

setting the dyed woven fabric in a matrix material.

8. The method of claim 1 , wherein the curvature of the four edges is configured to define a depth-wise curvature of an interior portion of the portable electronic device.

9. A method of manufacturing a portion of a portable electronic device, the method comprising:

interleaving fibrous weave layers with thermoplastic layers, wherein the fibrous weave layers comprise at least two layers having sheet metal antennas embedded between a first layer and a second layer;

applying a coating to the fibrous weave layers, the coating having a material and a thickness such that the coating does not substantially interfere with radio frequency (RF) functions of the portable electronic device, wherein the coating comprises a non-conductive vacuum metalized (NCVM) coating;

pressing the layers together with heat and pressure;

cooling the layers while under pressure to form a shaped body of continuous plastic with weave layers therein, wherein the shaped body comprises:

a substantially flat portion having four edges; and

a projection extending substantially perpendicularly away from the substantially flat portion and adjoining each of the four edges at a curvature;

providing for a coupling of the shaped body with a complementary part of the portable electronic device; and

connecting a rim to the projection of the shaped body without molding the rim on the shaped body.

10. The method according to claim 9 , wherein the fibrous weave layers comprise 1-3 layers of one or more of glass fiber, carbon fiber and nylon.

11. The method according to claim 9 , wherein the rim includes a connector for coupling with the complementary part.

12. The method according to claim 11 , wherein the connecting comprises at least one or more of adhering the rim to the projection of the shaped body and affixing the rim to the projection of the shaped body.

13. The method according to claim 9 , wherein an antenna is embedded in the flat portion of the body.
