Abstract: A method of forming a printed circuit board using an ink jet print head by printing a three dimensional groove using a curable, non-conductive deposition liquid and depositing a liquid that dries to form a conductive track. The walls on either side of the groove impede the liquid from spreading and consequently larger quantities of the conductive deposition liquid can be deposited without causing a short circuit. A multi layer printed circuit board can be produced by depositing further layers of curable non-conductive deposition liquid over the conductive track, a further conductive track in an upper layer being in contact with a conductive track in a lower layer along a slope formed from the non-conductive deposition liquid.
