Heat dissipation for a chip protected by an anti-tamper background

摘要

Systems and apparatus disclosed herein provide for heat dissipation from a chip protected by an anti-tamper material. An example electronic device includes a circuit board having electronics mounted thereon, and a security shield covering one or more electronics on the circuit board and configured to sense tampering, the one or more electronics including a chip, the security shield defining an aperture. The device also includes a heat sink extending through the aperture and thermally coupling with the chip, the heat sink extending outside of the security shield.

主权项

1. An electronic device comprising:
a circuit board having one or more electronics mounted thereon; a housing surrounding the circuit board, the housing comprising at least a first part attached to a second part, wherein the circuit board is mounted to the second part; a security shield integrated into the first part of the housing and covering the one or more electronics on the circuit board, wherein the one or more electronics are coupled to the security shield, wherein the one or more electronics sense tampering by detecting a change in the security shield, wherein the one or more electronics zeroize data stored in a memory device covered by the security shield in response to such tampering, wherein the one or more electronics include a chip, and the security shield defines an aperture; and a heat sink extending through the aperture and thermally conductively coupling with the chip, the heat sink extending outside of the security shield.
