Abstract
An apparatus includes a substrate and an electronic circuit comprising a plurality of conductive tracts forming a printed litz line on the substrate for distributing a signal therebetween in order to increase effective conductance relative to a single conductive line not divided into tracts. The plurality of conductive tracts may be formed by printing a pattern on the substrate and removing portions of the pattern to leave the plurality of conductive tracts. The removing portions of the pattern may be performed by a removal process such as laser cutting, milling, etching, or masking. For example, the removal may be performed by applying ultrashort laser pulses. The printing may be performed by a jetting process, a spray process, an extrusion process, a dispensing process, and/or other types of processes for applying materials.
