WEMA14: Precise measurements of the effective conductivity of copper foils and copper clad laminates for 5G/6G applications

Presentation Abstract
Development in high-speed communication systems requires minimization of signal loss in electronic devices. A choice of proper materials and precise measurements of their parameters, further used in the design process, are of crucial importance. Direct measurements of dielectric loss are well established in the industry, whereas only indirect methods of insertion loss measurements are used for conduction loss assessment. In this seminar, direct methods for 14-60GHz surface conductivity measurements, providing high accuracy and repeatability, are discussed. The seminar will feature measurement examples of copper foils and copper clad laminates, where effective conductivity is measured from both sides of the conductor
