Abstract

A laminate curtain can suppress electromagnetic radiation leakage from an electronic appliance, as well as assist in managing cables interconnected to the electronic appliance. More specifically, a laminate curtain can include a conductive elastomer panel that absorbs spurious electromagnetic radiation generated by the electronic appliance, a conductive adhesive film disposed along one side of the conductive elastomer panel, and a conductive support frame affixed to the conductive adhesive film. The laminate curtain can be installed within a mounting frame, which secures the laminate curtain to the electronic appliance. Electromagnetic radiation that is absorbed by the conductive elastomer panel can travel to the electronic appliance via the conductive adhesive film, the conductive support frame, and the mounting frame. Thus, the conductive elastomer panel can be used to form a ground plane that catches and shunts the spurious electromagnetic radiation to the electronic appliance, which is grounded.

First claim

What is claimed is:

1. A method of manufacturing a laminate curtain for absorbing electromagnetic radiation leaking from an electronic appliance chassis, the method comprising:
acquiring a conductive elastomer panel designed to absorb electromagnetic radiation over a first frequency range that corresponds to an electrical component housed in the electronic appliance chassis;
acquiring a radiation-absorbing panel designed to absorb substantially all electromagnetic radiation over a second frequency range of less than 4 gigahertz (GHz);
securing the radiation-absorbing panel to the conductive elastomer panel with an adhesive; and
securing a conductive support frame to the conductive elastomer panel with a conductive adhesive to form the laminate curtain.

2. The method of claim 1 , wherein the adhesive is not electrically conductive.

3. The method of claim 1 , further comprising:
cutting the laminate curtain to create a slot through which a cable can be routed.

4. The method of claim 1 , wherein the conductive support frame is designed such that the laminate curtain can be slidably engaged with a mounting frame connected to the electronic appliance chassis.

5. The method of claim 1 , wherein the radiation-absorbing panel is one of a plurality of radiation-absorbing panels secured to the conductive elastomer panel.

6. A method of manufacturing a laminate curtain for absorbing electromagnetic radiation leaking from an electronic appliance chassis, the method comprising:
acquiring a conductive elastomer panel designed to absorb electromagnetic radiation over a specified frequency range;
acquiring a plurality of radiation-absorbing panels designed to absorb electromagnetic radiation of different frequencies,
wherein each radiation-absorbing panel is designed to absorb electromagnetic radiation of a different frequency;

securing the plurality of radiation-absorbing panels to the conductive elastomer panel with an adhesive; and
securing a conductive support frame to the conductive elastomer panel with a conductive adhesive to form the laminate curtain.

7. The method of claim 5 , wherein the plurality of radiation-absorbing panels are secured to one another with a pressure-sensitive adhesive.

8. A method of manufacturing a laminate curtain, the method comprising:
acquiring a conductive elastomer panel designed to absorb electromagnetic radiation over a specified frequency range that corresponds to an electrical component housed in an electronic appliance chassis on which the laminate curtain is to be mounted;
applying a conductive adhesive film along a first side of the conductive elastomer panel;
securing a conductive support frame to the conductive adhesive film; and
affixing a plurality of stiffener components to exposed portions of the conductive adhesive film that are not in contact with the conductive support frame.

9. The method of claim 8 , wherein, when the laminate curtain is installed within a mounting frame connected to the electronic appliance chassis, the conductive support frame shunts at least a portion of the electromagnetic radiation absorbed by the conductive elastomer panel to the electronic appliance chassis.

10. The method of claim 8 , wherein each stiffener component is comprised of a non-conductive material.

11. The method of claim 8 , wherein each stiffener component is comprised of plastic, glass, or rubber.

12. The method of claim 8 , further comprising:
acquiring a plurality of radiation-absorbing panels designed to absorb electromagnetic radiation of different frequencies;
forming a radiation-absorbing stack by securing the plurality of radiation-absorbing panels to one another with a first adhesive; and
securing the radiation-absorbing stack to a second side of the conductive elastomer panel with a second adhesive.

13. The method of claim 12 , wherein the first and second adhesives are not electrically conductive.

14. The method of claim 8 , further comprising:
exposing the laminate curtain to a curing assembly for a specified duration.

15. The method of claim 14 , wherein the curing assembly includes a light source or a heat source.
