Electrophoretic deposition
View Patent ↗The present disclosure generally relates to systems, arrangements, and techniques for electrophoretic deposition of a plating material on a surface of a substrate. Example systems may include one or more of a substrate for receiving the plating material, a gel, a source element, and a conductive layer.
1. A system for electro-depositing a plating material on a surface of a substrate, wherein the surface of the substrate is configured to receive the plating material, the system comprising:
a first gel adapted for placement on the surface of the substrate;
a source element adapted for placement on the first gel, the source element comprising the plating material and a source gel, wherein the source gel is different from the first gel, and the plating material comprises metal ions suspended in the source gel; and
a conductive layer adapted for placement over the source element, wherein the conductive layer comprises a first electrode configured to couple an electrical current to the conductive layer to promote electro-deposition of the plating material on the surface of the substrate.
2. The system of claim 1 wherein the source element and the conductive layer comprise a single material.
3. The system of claim 1 , further comprising a second electrode adapted such that when the electrical current is coupled to the conductive layer, an electric field is formed between the first electrode and the second electrode to promote electro-deposition of the plating material on the surface of the substrate.
4. The system of claim 3 , wherein the substrate comprises the second electrode.
5. The system of claim 3 , wherein the first gel comprises the second electrode.
6. The system of claim 1 , wherein the first gel comprises an electrolyte gel.
7. The system of claim 6 , wherein the electrolyte gel comprises polyacrylimide or acrylose gel.
8. The system of claim 1 , wherein the source gel comprises an organic solvent to dissolve the plating material and a gelling agent to create a colloid mixture.
9. The system of claim 1 , wherein the first gel is provided at a thickness suitable for receiving stoichiometric products from the electro-deposition of the plating material.
10. The system of claim 9 , wherein the first gel is provided at a thickness of between approximately 0.1 and 10 mm.
11. The system of claim 1 , wherein the metal ions comprise copper, tin, zinc, or chrome ions, or a mixture thereof.
12. The system of claim 1 , wherein the plating material comprises a metal.
13. The system of claim 1 , wherein the plating material comprises ceramic.
14. The system of claim 1 , wherein the source element is reusable for electro-deposition steps onto multiple substrate surfaces.
15. The system of claim 1 , wherein the conductive layer comprises mylar foil.
16. The system of claim 1 , further comprising a power source that is configured to provide the electrical signal to the electrode.
17. The system of claim 1 , wherein the first gel, the source element, and the conductive layer are provided as a layered sheet component or layered tape component.
18. The system of claim 1 , wherein the first gel is not an electrolyte.
19. The system of claim 1 , wherein the first gel comprises a polar solvent.
