An interface to make interconnections between the interior and exterior of a sealed enclosure may include a flat connector (FC). The FC may comprise at least one layer of a substantially planar substrate. Each substrate layer may include metallization for conducting signals between contacts on an interior-facing surface and contacts on an exterior-facing surface. In an enclosure with an aperture for passing electrical conductors, the FC may be configured to seal the aperture to inhibit the escape of a low density gas, such as helium, for a long period of time. In one embodiment, the FC may include metallization configured to minimize helium leakage. As such, the FC may conduct electrical signals into and out of the sealed enclosure. Such signals may include, for example, power, control, and data signals for operating devices housed within the enclosure.

What is claimed is: 1. A method of hermetically sealing an aperture in an enclosure, the method comprising: providing a base portion of the enclosure, the base portion having an aperture in a first wall; and mounting a flat connector (FC) to the first wall, the FC comprising: a first outer layer containing a first set of contacts; a second outer layer opposite the first outer layer and containing a second set of contacts, wherein at least one of the contacts in the first set of contacts is electrically connected to at least one contact in the second set of contacts through at least one electrically conductive path; and at least one substrate layer separating the first and second outer layers and containing a portion of each of the at least one conductive path. 2. The method of claim 1, wherein at least two of the layers of the FC provide a low permeability barrier to a gaseous medium. 3. The method of claim 2, wherein the gaseous medium comprises helium. 4. The method of claim 2, wherein the substrate layer comprises FR4 material and the first and second layers comprise a conductive metal substantially covering the area encompassed by the FC. 5. The method of claim 2, wherein the substrate layer comprises a ceramic material. 6. The method of claim 2, wherein the FC further comprises an optical path for coupling an optical signal through the FC. 7. The method of claim 2, wherein the enclosure comprises stainless steel. 8. The method of claim 2, wherein the enclosure comprises aluminum. 9. The method of claim 2, wherein mounting the FC comprises soldering a peripheral ring of exposed metal on one of the outer layers of the FC to the first wall of the enclosure. 10. The method of claim 9, wherein the FC is mounted on an interior surface of the first wall. 11. The method of claim 9, wherein the FC is mounted on an exterior surface of the first wall. 12. The method of claim 2, wherein the FC sealably encompasses the aperture to inhibit escape of the gaseous medium from within the enclosure to an external ambient environment. 13. The method of claim 2, wherein mounting the FC comprises adhesively bonding to the periphery of the FC, wherein the bonding adhesive has a low permeability to the gaseous medium. 14. The method of claim 1, wherein the FC further comprises a first internal conductive layer disposed between two substrate layers, the first internal conductive layer including interconnections between a first set of vias that are electrically coupled to the first set of contacts and a second set of vias that are electrically coupled to the second set of contacts. 15. A method of making electrical connection through an aperture in a wall, the method comprising: providing a flat connector (FC) comprising: a first outer layer containing a first set of contacts; a second outer layer opposite the first outer layer and containing a second set of contacts, wherein at least one of the contacts in the first set of contacts is electrically coupled to at least one contact in the second set of contacts through at least one electrically conductive path; and at least two substrate layer separating the first and second outer layers and containing a portion of each of the at least one conductive path; a first internal conductive layer disposed between two substrate layers, the first internal conductive layer including interconnections between a first set of vias that are electrically coupled to the first set of contacts and a second set of vias that are electrically coupled to the second set of contacts; and sealably attaching the FC to the wall such that the FC sealably encompasses the aperture in the wall. 16. The method of claim 15, wherein mounting the FC comprises soldering a peripheral ring of exposed metal on one of the outer layers of the FC to the wall. 17. The method of claim 15, wherein mounting the FC comprises adhesively bonding to the periphery of the FC, wherein the bonding adhesive has a low permeability to helium.
