For FR4: c Signal ≈ 150 000 km/s Due to the finite propagation speed, the following rule of thumb formula applies: The spatial dependence of voltage and currents becomes significant for a conductor length > λ / 10.. Field Solver 8 0 from Polar Instruments is used to calculate the impedances On request we can produce your circuit boards to include a test coupon for impedance measurement and subsequently evaluate it with the aid of a modern TDR (Time Domain Reflectometer) cable radar.. This propagation speed depends on the material used (ε dielectric constant) and can be determined approximately with the formula c Signal ≈ c Licht / √ε r.. Impendence matching should be implemented to avoid transmission faults Production-compatible conductor tracks can be realised for impedance-matched system through the use of microvias. HERE
