Abstract:
1. A method of rendering a printed circuit board (PCB) using liquid electrophotographic printing, comprising: electrophotographically printing a first layer of electrically conductive ink traces on a photosensitive belt in a liquid electrophotographic printing device upon a first transfer medium; printing at least one area of dielectric ink upon at least one printed trace; printing a second layer of conductive traces atop the first layer, the dielectric ink insulating at least a portion of the second layer from the first layer; forming a boundary delineation between contacting portions of the electrically conductive ink traces and the dielectric ink such that the electrically conductive ink traces and the dielectric ink are substantially immiscible; and transferring the printed first layer, the printed at least one area of dielectric ink, and printed second layer to a provided substrate with a transfer medium disposed proximate to the photosensitive belt and located in the liquid electrophotographic printing device.
