Based on personal experience, the author shares the experience of switching from FR4 substrate to PTFE material, pointing out the crucial role of dielectric loss, dielectric constant, and metal substrate selection in practical design. Especially in high-speed signal scenarios, material selection is often more important than layout. If you also encounter signal distortion or..."}
