The enclosure structure includes a housing comprising one or more cavities for receiving one or more electronic components within an interior of the housing and a bore through the housing. The one or more electronic components comprises a connector element and the bore comprises a non-tapered portion and a tapered portion. The non-tapered portion is proximate to the interior of the housing and the tapered portion is proximate to the exterior of the housing. The bore is configured to receive a feedthrough pin for coupling the connector element to an external component external to the enclosure structure. The enclosure structure also includes a feedthrough pin extending through the bore and a potting material disposed within the tapered portion surrounding the feedthrough pin. ## Claims ### Claim 1 (canceled) ### Claim 2 An enclosure structure suitable for high-pressure environments, the enclosure structure comprising: a circuit board assembly comprising one or more circuit components mounted on a surface of a circuit board; and a housing configured to distribute pressure positioned over the circuit board assembly, wherein the housing comprises: one or more areas conforming to and in contact with one or more corresponding sections of the surface, and one or more cavities, each cavity configured to receive one of the one or more circuit components, the one or more cavities comprising a first cavity having a first volume larger than a volume of a corresponding first circuit component of the one or more circuit components so as to create a first gap between the housing and the first circuit component, the enclosure structure having a feedthrough for coupling one or more circuit components housed within the enclosure structure to components external to the enclosure structure; a bore through the housing, wherein the bore comprises a non-tapered portion and a tapered portion, the non-tapered portion being proximate to an interior of the housing and the tapered portion being proximate to an exterior of the housing, and wherein the bore is configured to receive a feedthrough pin for coupling a connector element of one or more circuit components to an external component external to the enclosure structure; and a feedthrough pin extending through the bore, the feedthrough pin having a first end and a second end, wherein the first end is configured to be coupled to the connector element and the second end is configured to be coupled to the external component. ### Claim 3 (depends on 2) The enclosure of claim 2 wherein the one or more cavities further comprise a second cavity, and wherein the one or more circuit components further comprises a corresponding second circuit component, the second cavity having a second volume that is larger than a volume of a corresponding second circuit component so as to create a second gap between the housing and the second circuit component. ### Claim 4 (depends on 3) The enclosure of claim 3 wherein the one or more cavities further comprise a third cavity, and wherein the one or more circuit components further comprises a corresponding third circuit component, the third cavity having a third volume larger than a volume of a corresponding third circuit component so as to create a third gap between the housing and the third circuit component. ### Claim 5 (depends on 2) The enclosure structure of claim 2 further comprising an envelope surrounding the housing, wherein the envelope is impermeable to water when the enclosure structure is held at 15,750 pounds per square inch, and wherein the feedthrough pin extends to an exterior of the envelope. ### Claim 6 (depends on 5) The enclosure structure of claim 5 further comprising an envelope cap disposed on the exterior of the envelope, wherein the feedthrough pin extends to the exterior of the envelope via the envelope cap. ### Claim 7 (depends on 6) The enclosure structure of claim 6 wherein the envelope cap comprises: an envelope-cap bore through which the feedthrough pin extends, the envelope-cap bore comprising a tapered portion; and a potting material disposed within the envelope-cap bore surrounding the feedthrough pin. ### Claim 8 (depends on 5) The enclosure structure of claim 5 wherein the envelope comprises an elongated portion, wherein the feedthrough pin extends to the exterior of the envelope via the elongated portion, and wherein the enclosure structure further comprises a sealing structure disposed around at least part of the elongated portion. ### Claim 9 (depends on 8) The enclosure structure of claim 8 wherein the sealing structure comprises a heat shrink tubing. ### Claim 10 (depends on 5) The enclosure structure of claim 5 wherein the envelope comprises a mylar-based material or a plastic material. ### Claim 11 The enclosure structure of claim wherein the housing comprises a fiberglass composite material. ### Claim 12 (depends on 2) The enclosure structure of claim 2 further comprising: a potting material disposed within the tapered portion surrounding the feedthrough pin; and a housing cap disposed along the exterior of the housing over the potting material. ### Claim 13 (depends on 12) The enclosure structure of claim 12 wherein the potting material is an epoxy. ### Claim 14 (depends on 2) The enclosure structure of claim 2 wherein the tapered portion comprises an interior end facing the interior of the housing and an exterior end facing an exterior of the housing, wherein a cross-section of the interior end is less than a cross-section of the exterior end. ### Claim 15 (depends on 14) The enclosure structure of claim 14 wherein the non-tapered portion comprises a cylindrical portion, and wherein the tapered portion comprises a conical portion. ### Claim 16 An enclosure structure comprising: a housing configured to be positioned over a circuit board assembly, wherein the housing comprises: one or more areas configured to conform to and contact with one or more corresponding sections of a surface of the circuit board assembly, and one or more cavities, each cavity configured to receive one or more circuit components of the circuit board assembly, the one or more cavities comprising a first cavity having a first volume larger than a volume of a corresponding first circuit component of the one or more circuit components so as to create a first gap between the housing and the first circuit component, the enclosure having a feedthrough for coupling one or more circuit components housed within the enclosure structure to components external to the enclosure structure; a bore through the housing, wherein the bore comprises a non-tapered portion and a tapered portion, and wherein the bore is configured to receive a feedthrough pin for coupling a connector element of one or more circuit components to a component external to the enclosure structure; a feedthrough pin extending through the bore, the feedthrough pin having a first end and a second end, wherein the first end is configured to be coupled to the connector element and the second end is configured to be coupled to the external component.
