WebNov 10, 2024 · FR4 can be used for high-speed PCB design when the layers are laminated with high-speed laminates such as Rogers. At high-frequency, FR4 experiences dispersion, which increases the speed and … WebFor these designs, FR4 is not an ideal choice — FR4 has a higher Df, or dissipation factor, than high-frequency laminates. This means FR4 circuits will suffer more signal loss than an identical circuit on a high-frequency laminate. The Df of FR4 is around 0.020, while the Df of most high-frequency laminates is around 0.004, a fourth of FR4 ...
