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.

Claims (20)

1. A method of manufacturing an electronic device, comprising:

enclosing electronic components in a temperature controlled chamber, wherein enclosing the electronic components in the temperature controlled chamber comprises hermetically sealing the temperature controlled chamber;

packaging a plurality of capillary tubes, a substrate, and the temperature controlled chamber in a vacuum chamber;

providing an outer shell having a low pressure chamber to house the temperature controlled chamber; and

providing a second set of capillary tubes to support the plurality of capillary tubes attached to the substrate.

2. The method of claim 1 , further comprising coating the temperature controlled chamber in a low emissive material.

3. The method of claim 1 , wherein packaging the plurality of capillary tubes and the substrate comprises attaching the plurality of capillary tubes to the substrate using epoxy.

4. An oven-controlled crystal oscillator comprising:

a temperature controlled chamber disposed within a vacuum packaged assembly;

a crystal oscillator disposed within the temperature controlled chamber, wherein the temperature controlled chamber is a solid material housing the crystal oscillator and a temperature sensor; and

an outer shell having a low pressure chamber to house the temperature controlled chamber.

5. The oven-controlled crystal oscillator of claim 4 , further comprising:

a plurality of capillary tubes electrically coupled to the crystal oscillator, wherein:

a first end of each of the plurality of capillary tubes is coupled to the temperature controlled chamber; and

a second end of each of the plurality of capillary tubes is coupled to a support structure.

6. The oven-controlled crystal oscillator of claim 5 , wherein the low pressure chamber also houses the plurality of capillary tubes.

7. The oven-controlled crystal oscillator of claim 5 , further comprising: a second plurality of capillary tubes having a hollow core and a polymer coating, wherein the second plurality of capillary tubes is not coupled to the temperature controlled chamber.

8. The oven-controlled crystal oscillator of claim 7 , wherein the plurality of capillary tubes and the second plurality of capillary tubes form a mesh to support the temperature controlled chamber.

9. The oven-controlled crystal oscillator of claim 5 , wherein the plurality of capillary tubes is electrically coupled to the crystal oscillator through an electrically conductive layer of the plurality of capillary tubes.

10. The oven-controlled crystal oscillator of claim 4 , further comprising an external structure operatively coupled with the temperature controlled chamber.
