An article having an electrical circuit component printed directly onto one side of a substrate includes the substrate and an electrical circuit component formed of a conductive liquid printed directly onto one side of the substrate. The electrical component is capable of performing its electrical circuit functions, as printed, and without the necessity for post-printing processes such as metal etching, catalytic ink activation, or electroless deposition.

Electrical circuit component formed of a conductive liquid printed

Apparatus and process for directly printing an electrical circuit component onto a substrate includes structure and steps for providing a printing station, and for transporting the substrate to the printing station. Structure and steps are provided for printing, at the printing station, an electrical circuit component on the substrate using an electrically-conductive liquid. Preferably, the printed electrical circuit component is capable of performing its circuit function directly after printing, without the need for post-printing process steps such as etching, catalytic ink activation, electroless bath, etc.

Apparatus for printing an electrical circuit component with print cells

A press for printing an electrical circuit component directly onto a substrate with an electrically-conductive liquid includes a press surface having a printing direction and a direction transverse thereto. A plurality of liquid-carrying cells are disposed on the press surface for carrying the electrically-conductive liquid, the cells being in liquid communication with each other in both the printing direction and in the transverse direction. A method of making such a press includes the steps of providing a press surface and engraving the press surface with the plurality of liquid-carrying cells which are in liquid communication with each other in both the printing direction and in the transverse direction.

Press for printing an electrical circuit component directly onto a

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.
