Abstract

In one or more embodiments, a device may include a printed circuit board that includes at least two exposed conductor traces on a first side of the printed circuit board that are not in contact with each other; a material, that includes a substance that forms an electrically conductive solution when dissolved by a polar solvent, in contact with the at least two exposed conductor traces and fastened to at least one of the printed circuit board and the at least two exposed conductor traces; and a fastener on a second side of the printed circuit board, opposite the first side of the printed circuit board, among others.

Claims (24)

1. A device, comprising:

a printed circuit board that includes at least two exposed conductor traces on a first side of the printed circuit board that are not in contact with each other;

a material, which includes a substance that includes a soluble salt and that forms an electrically conductive solution when dissolved by a polar solvent, in contact with the at least two exposed conductor traces, fastened to at least one of the printed circuit board and the at least two exposed conductor traces, and configured to lower a resistance between the at least two exposed conductors when the electrically conductive solution is formed; and

a fastener on a second side of the printed circuit board, opposite the first side of the printed circuit board, configured to fasten the printed circuit board to a surface.

2. The device of claim 1 , wherein the soluble salt includes at least one of sodium chloride (NaCl), potassium chloride (KaCl), and sodium bicarbonate (NaHCO 3 ).

3. The device of claim 1 , wherein the fastener on the second side of the printed circuit board includes an adhesive.

4. The device of claim 1 , wherein the resistance between the at least two exposed conductors is less than one hundred ohms when the polar solvent is applied to the material.

5. The device of claim 1 , wherein the material includes a plurality of pores that permit the electrically conductive solution to be transferred to the at least two exposed conductors.

6. The device of claim 1 , wherein the material is hygroscopic.

7. The device of claim 1 , wherein the material is associated with a rectangular shape.

8. The device of claim 1 , wherein the material is associated with a circular shape.

9. The device of claim 1 , wherein the printed circuit board is a non-flexible printed circuit board.

10. The device of claim 1 , wherein the printed circuit board is a flexible printed circuit board.

11. The device of claim 1 , wherein the at least two exposed conductor traces are not covered by a solder mask.

12. The device of claim 1 , wherein the at least two exposed conductor traces form a spiral pattern.

13. The device of claim 1 , wherein the at least two exposed conductor traces form an “E” pattern.

14. The device of claim 1 ,

wherein the surface includes at least a portion of a second circuit board of an information handling system;

wherein an information handling system includes the second circuit board; and

wherein the second circuit board includes a plurality of circuit board traces.

15. The device of claim 1 , wherein the substance, when dissolved by the polar solvent, dissociates into ions and acquires a capacity to conduct electricity between the at least two exposed conductor traces.

16. The device of claim 1 , wherein the substance, when dissolved by the polar solvent, separates into cations and anions.

17. The device of claim 1 , wherein the polar solvent includes water.

18. The device of claim 1 , wherein the polar solvent is water.
