Abstract

This is directed to several handheld device components to be placed in a handheld device, as well as methods or systems for mounting or retaining components within the device. In particular, this is directed to a rigid shield used in an SMT process and securing connected flex connectors by adhering the flexes together. This is also directed to using foam in combination with a hard material to create an acoustic seal, or several layers of foam to create an acoustic and mechanical seal. This is also directed to selectively folding a sheet of material placed around a battery cell.

First claim

The invention claimed is:

1. An electronic device comprising:
an enclosure;
a flexible circuit disposed along a periphery of the enclosure and comprising a fold defining an upper fold section and a lower fold section;
a first component mounted on the lower fold section of the flexible circuit and positioned adjacent to a sidewall of the enclosure;
a second component mounted on the upper fold section of the flexible circuit and separated from the first component and from the sidewall; and
an electromagnetic interference shield coupled to the flexible circuit, the electromagnetic interference shield positioned between the first and second components and structurally supporting the second component thereby shielding the second component from the first component; wherein
the first component is at least a portion of a wireless communication module.

2. The electronic device of claim 1 , wherein:
the first component is affixed to a first surface of the flex; and
the electromagnetic interference shield is affixed to a second, different surface of the flex.

3. The electronic device of claim 2 , wherein:
the first surface comprises a first side of the flex; and
the second surface comprises a second side of the flex.

4. The electronic device of claim 3 , wherein the second component is mounted to the first surface of the flex.

5. The electronic device of claim 1 , wherein the first component is electrically insulated from the electromagnetic interference shield.

6. The electronic device of claim 1 , wherein the electromagnetic interference shield structurally supports at least a portion of the flex.

7. The electronic device of claim 6 , wherein the first component is mounted to the at least a portion of a flex.

8. The electronic device of claim 1 , wherein the electromagnetic interference shield is planar.

9. An electronic component array, comprising:
a substrate disposed along a periphery of an interior surface a housing of an electronic device;
a first component affixed to a first side of the substrate and configured to be positioned adjacent to a first portion of the interior surface;
a second component affixed to the first side of the substrate and configured to be positioned adjacent a second portion of the interior surface; and
a rigid planar shield disposed on a second side of the substrate opposite the second component and, when the substrate is folded to an acute angle along a fold axis defined between the first component and the second component the rigid planar shield is positioned between the first and second components; wherein
the rigid planar shield redirects electromagnetic radiation generated by the first component thereby shielding the second component from the first component; and
the first component is at least a portion of a wireless communication circuit.

10. The electronic component array of claim 9 , wherein the rigid planar shield structurally supports the first component.

11. The electronic component array of claim 10 , wherein:
the substrate comprises:
a bend portion;
a first portion adjacent the bend portion; and
a second portion adjacent the bend portion; and

the substrate bends at the bend region such that the second portion either overlies or underlies the first portion.

12. The electronic component array of claim 11 , wherein:
the first component is affixed to the first side in the first portion; and
the second component is affixed to the first side in the second portion.

13. The electronic component array of claim 11 , further comprising a third component affixed to the second side of the substrate; wherein
the rigid planar shield blocks at least some additional electromagnetic radiation generated by the third component from reaching the first component.

14. The electronic component array of claim 13 , wherein the substrate is between the first component and the rigid planar shield, but not between the third component and the rigid planar shield.

15. The electronic component array of claim 11 , wherein the second component is one of a communications module and an inductor.
