ELECTRONIC PACKAGE WITH HEAT TRANSFER ELEMENT(S)

摘要

Electronic packages are provided with enhanced heat dissipation capabilities. The electronic package includes a plurality of electronic components, and an enclosure in which the electronic components reside. The enclosure includes a thermally conductive cover overlying the electronic components. At least one heat transfer element is coupled to, or integrated with, the thermally conductive cover and resides between a main surface of the cover and at least one respective electronic component of the plurality of electronic components. A thermal interface material is disposed between the heat transfer element(s) and the respective electronic component(s), and facilitates conductive transfer of heat from the electronic component(s) to the thermally conductive cover through the heat transfer element(s). The thermally conductive cover facilitates spreading and dissipating of the transferred heat outwards, for instance, through a surrounding tamper-respondent sensor and/or a surrounding encapsulant.
