Signal Transmission Loss due to Copper Surface Roughness in High-Frequency Region

Apr 30, 2015 | Elaine Liew, Mitsui Copper Foil Malaysia, Shah Alam Malaysia Taka-aki Okubo, Toshio Sudo, Shibaura Institute of Technology, Tokyo Japan Toshihiro Hosoi, Hiroaki Tsuyoshi, Fujio Kuwako, Mitsui Kinzoku Co., Ltd, Japan.

Higher-speed signal transmission is increasingly required on a printed circuit board to handle massive data in electronic systems. So, signal transmission loss of copper wiring on a printed circuit board has been studied. First, total signal loss was divided into dielectric loss and conductor loss quantitatively based on electromagnetic theory. In particular, the scattering loss due to surface roughness of copper foil has been examined in detail. And the usefulness of the copper foil with low surface roughness has been demonstrated....
