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 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.
