Tamper-respondent assembly with vent structure
First Claim
1. A tamper-respondent assembly comprising:
- an electronic enclosure to enclose, at least in part, at least one electronic component to be protected, the electronic enclosure comprising an inner surface and an air vent through a wall of the electronic enclosure, the air vent being disposed, at least in part, at a corner of the electronic enclosure;
a tamper-respondent electronic circuit structure disposed within the electronic enclosure and comprising a tamper-respondent sensor covering, at least in part, the inner surface of the electronic enclosure, including the air vent, and defining, at least in part, a secure volume about the at least one electronic component; and
a vent structure located within the electronic enclosure, and comprising at least one air passage coupling in fluid communication the secure volume and the air vent of the electronic enclosure to allow air pressure within the secure volume to equalize with air pressure external to the tamper-respondent assembly, the vent structure including opposite ends, one end of the opposite ends being located within the secure volume and another end of the opposite ends being located at the air vent in the electronic enclosure, wherein the vent structure resides between, at least in part, the inner surface of the electronic enclosure and the tamper-respondent sensor.

Abstract
Tamper-respondent assemblies, electronic packages and fabrication methods are provided which incorporate a vent structure. The tamper-respondent assembly includes an electronic enclosure to enclose, at least in part, an electronic component(s) to be protected. The electronic enclosure includes an inner surface, and an air vent. A tamper-respondent electronic circuit structure is provided which includes a tamper-respondent sensor disposed to cover, at least part, the inner surface of the electronic enclosure, and define, at least in part, a secure volume about the electronic component(s). The vent structure includes at least one air passage coupling in fluid communication the secure volume and the air vent of the electronic enclosure to allow air pressure within the secure volume to equalize with air pressure external to the tamper-respondent assembly.
