Description: 1, how to choose the PCB board? Select the PCB board must meet the design requirements and production and cost the middle point of balance. Design requirements include both electrical and body parts. Usually very high-speed PCB design board (greater than GHz frequencies) when this problem would be more important material. For example, the now commonly used FR-4 material, the frequency of several GHz, the media loss (dielectric loss) would have great impact on signal attenuation may not be combined. The electrical, in order to pay attention to the dielectric constant (dielectric constant) and media loss in the suitability of the design frequency.
