Abstract

A device may include a temperature controlled chamber. The temperature controlled chamber may be coupled to a plurality of strengthening coated capillary tubes. The strengthening coated capillary tubes may support the temperature controlled chamber and provide thermal insulation to the temperature controlled chamber.

First claim

What is claimed is:

1. A packaged electronic device comprising:
a temperature controlled chamber;
a plurality of capillary tubes coupled to the temperature controlled chamber, wherein the plurality of capillary tubes support the temperature controlled chamber and operatively couple the temperature controlled chamber to an external structure; and
an outer shell having a low pressure chamber to house the temperature controlled chamber.

2. The device of claim 1 , wherein at least a subset of the capillary tubes have an electrically conductive coating to provide an electrical connection from the temperature controlled chamber to a pin of a shell housing the temperature controlled chamber.

3. The device of claim 2 , wherein the electrically conductive coating partially covers a circumference of the plurality of capillary tubes.

4. The device of claim 2 , wherein the electrically conductive coating comprises one of copper, gold, silver, conductive epoxy, Indium Tin Oxide, titanium, or nickel.

5. The device of claim 1 , further comprising a crystal oscillator housed inside the temperature controlled chamber.

6. The device of claim 1 , wherein an exterior surface of the temperature controlled chamber is coated with one of aluminum, silver, copper, gold, or pallium.

7. A packaged electronic device comprising:
a temperature controlled chamber; and
a plurality of capillary tubes coupled to the temperature controlled chamber, wherein the plurality of capillary tubes support the temperature controlled chamber and operatively couple the temperature controlled chamber to an external structure, wherein the plurality of capillary tubes comprise:
a tube body having a hollow core; and
a strengthening coating on an exterior surface of the tube body.

8. The device of claim 7 , wherein the strengthening coating comprises one of polyimide, polyamide, parylene, or Polydimethylsiloxane (PDMS).

9. The device of claim 7 , wherein the tube body comprises on of silica, ceramic, or a polymer.

10. A packaged electronic device comprising:
a temperature controlled chamber; and
a plurality of capillary tubes coupled to the temperature controlled chamber, wherein the plurality of capillary tubes support the temperature controlled chamber and operatively couple the temperature controlled chamber to an external structure, wherein:
a first subset of the plurality of strengthening coated capillary tubes is bonded to the temperature controlled chamber; and
a second subset of the plurality of strengthening coated capillary tubes is not bonded to the temperature controlled chamber.

11. The device of claim 10 , wherein the second subset of the plurality of strengthening coated capillary tubes have point contacts with the first subset of the plurality of strengthening coated capillary tubes to form a mesh.
