Abstract
An apparatus and method for making a printed circuit board comprising a substrate and an electrical circuit is provided. The circuit is formed by deposition of a plurality of electronic inks onto the substrate and curing of each of the electronic inks. The deposition may be performed using an ink-jet printing process. The inkjet printing process may include the step of printing a plurality of layers, wherein a first layer includes at least one electronic ink deposited directly onto the substrate, and wherein each subsequent layer includes at least one electronic ink deposited on top of at least a portion of a previous layer when the previous layer has been cured. One or more of the layers may include at least two of the electronic inks.
