What Is a PTFE PCB? A PTFE PCB is a printed circuit board made from polytetrafluoroethylene (PTFE) laminates, known for extremely low dielectric loss, stable dielectric constant, and excellent high-frequency performance. PTFE PCBs are widely used in 5G, mmWave modules, RF/microwave systems, aerospace electronics, and high-speed computing, where signal integrity and low insertion loss are...
