ABSTRACT:
The invention provides a printed circuit board (PCB) printing system. In a particular embodiment, the system includes a liquid electrophotographic printing device. At least one supplier of electrically conductive ink supplying electrically conductive ink to the electrophotographic printing device is also provided. In addition, at least one supplier of dielectric ink supplying dielectric ink to the electrophotographic printing device is also provided. The liquid electrophotographic printing device is operable to apply the electrically conductive ink and the dielectric ink to a provided substrate such that substantially immiscible boundary delineation occurs at any points of contact between the applied electrically conducive ink and the applied dielectric ink. An appropriate method of use for the rendering of a printed circuit board is also provided.
