Abstract
A circuit apparatuses include at least one circuit feature formed from patterning a conductive sheet. The conductive sheet includes an irregular surface and a planarized surface. Conductive sheet roughness is minimized in first regions of the circuit apparatus and is maintained in second regions of the circuit apparatus. Selectively planarizing portions of the conductive sheet allows for the utilization of lower cost rougher conductive sheets. The planarized surface allows for increased signal integrity and reduced insertion loss and the irregular surface allows for increased adhesion and enhancing reliability of the circuit apparatus.
