Shield for an electronic device
Example embodiments relate to a shield for an electronic device. The shield may be shaped to enclose the electronic device. The shield may include a number of traces. Each trace may include an electrically conductive inner portion and an electrically non-conductive outer portion.
1. An apparatus for providing a security barrier, the apparatus comprising:
a shield comprising a plurality of traces, wherein each trace comprises an inner portion and an outer portion, the inner portion comprising conductive plastic and the outer portion comprising non-conductive plastic, and wherein the plurality of traces is arranged such that the shield is shaped to enclose an electronic device, wherein the shield defines an air channel that supports air flow from external to the shield to an interior of the shield and vice versa, and the air channel includes multiple directional changes for the air flow;
a metal shell enclosing the shield; and
a thermally conductive material provided between the metal shell and the shield.
2. The apparatus of claim 1 , further comprising pressure-sensitive material provided between the metal shell and the shield.
3. The apparatus of claim 1 , further comprising electrically conductive material provided between the metal shell and the shield.
4. The apparatus of claim 1 , wherein the metal shell comprises an edge from which two surfaces of the metal shell extend at ninety degrees relative to each other, a portion of the shield proximate the edge forming a surface that forms an angle with each of the two surfaces of the metal shell, wherein the angle is in a range of between thirty-five degrees and fifty-five degrees.
5. The apparatus of claim 1 , wherein the metal shell comprises a corner from which three surfaces of the metal shell extend at ninety degrees relative to each other, a portion of the shield proximate the corner having a surface that forms an angle with each of the three surfaces of the metal shell, wherein the angle is in a range of between thirty-five degrees and fifty-five degrees.
6. A system comprising:
an electronic device comprising memory;
a shield comprising a plurality of traces, wherein each trace comprises a conductive plastic inner portion and a non-conductive plastic outer portion, the plurality of traces being arranged such that the shield encloses the electronic device, wherein the shield defines an air channel that supports air flow from external to the shield to an interior of the shield and vice versa, and the air channel includes multiple directional changes for the air flow; and
a plurality of decoy traces, wherein a first current is caused to flow through the plurality of traces, and a second current is caused to flow through the plurality of decoy traces.
7. The system of claim 6 , wherein at least some of the traces are shaped as a spiral, and wherein at least some of the decoy traces extend along a center line of the spiral.
8. The system of claim 6 , wherein at least some of the decoy traces are shaped as a spiral, and wherein at least some of the traces extend along a center line of the spiral.
9. The system of claim 6 , wherein the plurality of traces is coupled to the electronic device, and in response to detecting penetration by a source external to the shield, the memory is caused to be erased.
10. The system of claim 6 , wherein the plurality of traces is generated using three-dimensional printing.
