The electrical characteristics extracting technology for single and composite flexible print circuit materials

Technology of electrical characteristics extraction about FPC is proposed in this study. It makes use of the basic concepts of transmission line to derive the method of dielectric extraction.For analysis of single and composite about FPC material, that makes use of the different resonance point to extract the parameter of material for multiple samples. In order to prove the feasibility of extracted method, it would import the extracted parameter of material into simulation software to compare the difference between simulation and measurement, the range is 0.5GHz to 10 GHz. It can be discovered that the extracted method is accurate for comparing results. Finally, because of the complexity of composite material, this study will explain how to make use of simulation setting to improve the result of multi-tier architecture. These can help designers to design and analyze circuits.
