Abstract:
1. An electronics enclosure for providing passive cooling of electronic components while reducing electromagnetic interference (EMI) emissions, the electronics enclosure comprising: an electronics assembly comprising a planar substrate and at least one electronic component, the planar substrate including a conductive strip around a portion of a periphery of an upper surface of the planar substrate; a heat sink coupled to the electronics assembly, the heat sink comprising a base portion configured to thermally couple to the at least one electronic component when the heat sink is coupled to the electronic assembly; and a conductive enclosure forming an enclosed volume around the electronics assembly, the enclosure comprising a first opening configured to fit around the heat sink, at least one second opening formed in the conductive enclosure spaced from the first opening, and a flange configured to mate with the conductive strip when the conductive enclosure is coupled with the planar substrate; wherein all non-conductive passages from the volume to the external environment have at least one cross-sectional opening having a continuous conductive perimeter with a maximum linear length within the opening of less than one quarter a wavelength of a determined maximum shielding frequency.
