Electrically-conductive liquid for directly printing an electrical circuit component onto a substrate, and a method for making such a liquid

摘要

An electrically-conductive liquid for directly printing an electrical circuit component onto a substrate includes between substantially 25 percent and substantially 85 percent by weight of a solvent or water. Between substantially 10 percent and substantially 40 percent by weight of solids are provided, the solids including (i) substantially 5 percent to substantially 30 percent of polymer resin, and (ii) substantially 3 percent to substantially 15 percent by weight of a conductive powder. Between substantially 1 percent and substantially 7 percent by weight of plasticizers are also included. A method of making such an ink includes the steps of premixing the above-referenced solids and the above-referenced plasticizers, and then mixing the premix with the above-referenced solvent or water.
