Looking for a reliable partner in PTFE PCB manufacturing? We specialize in high-frequency PCB production using advanced PTFE-based materials from top suppliers like Rogers, Taconic, Arlon, and Isola. With decades of experience and precision-focused processes, we deliver low-loss, high-stability PCBs tailored for RF, microwave, and millimeter-wave applications—on time and to spec.
PTFE PCB Manufacturing Services
PTFE (Polytetrafluoroethylene) based laminates represent the gold standard for high-frequency PCB applications demanding ultra-low loss and stable electrical properties. We process all major PTFE material systems including pure PTFE, ceramic-filled PTFE, and glass-reinforced PTFE composites from leading suppliers like Rogers, Taconic, Arlon, and Isola. Our expertise spans Rogers RT/duroid series (5870, 5880, 6002), Taconic RF and TLY series, Arlon DiClad and CuClad series, delivering consistent results with dielectric constants ranging from 2.1 to 10.2 and dissipation factors as low as 0.0009.
The unique properties of PTFE - including its low dielectric constant, minimal moisture absorption, and exceptional chemical resistance - require specialized handling throughout the manufacturing process. Our climate-controlled facility maintains optimal temperature and humidity levels to prevent dimensional changes during processing. We employ dedicated tooling for PTFE materials to avoid cross-contamination and ensure pristine surface quality essential for reliable copper adhesion.
Specialized Manufacturing Processes for PTFE Circuit Boards
PTFE PCB fabrication demands precise control at every stage due to the material's unique characteristics. Our drilling operations utilize specialized carbide drill bits with optimized geometries to manage PTFE's tendency to smear and deform. We maintain strict control over drilling parameters including spindle speed (typically 50-70k RPM), feed rates, and pecking cycles to achieve clean hole walls essential for reliable plated through holes. Entry and exit materials are carefully selected to minimize burring and fiber protrusion.
Surface preparation for PTFE substrates employs sodium etching or plasma treatment to modify the naturally non-stick surface for enhanced copper adhesion. Our metallization process includes specialized seed layers and electroless copper formulations optimized for PTFE materials. The subsequent electrolytic plating builds copper thickness while maintaining uniform distribution critical for impedance control in microstrip and stripline configurations.

Applications Driving PTFE PCB Demand
Aerospace and Satellite Communications
PTFE PCBs excel in space-qualified applications where low outgassing, radiation resistance, and stable performance across extreme temperatures are mandatory. We support satellite payload manufacturers with flight-qualified PTFE boards for Ka-band and Ku-band transponders, phased array antennas, and low-noise amplifiers operating from L-band through W-band frequencies.
5G and Wireless Infrastructure
The rollout of 5G networks drives demand for low-loss PTFE PCBs in massive MIMO antennas, beamforming networks, and millimeter-wave front-end modules. Our manufacturing processes ensure phase matching within ±3 degrees for antenna arrays and maintain insertion loss specifications critical for link budget optimization in 28 GHz and 39 GHz deployments.
Automotive Radar and Medical Devices
PTFE-based PCBs enable 77 GHz automotive radar sensors with superior range resolution and minimal signal attenuation. In medical applications, PTFE's biocompatibility and low loss support MRI coils, microwave ablation devices, and wireless patient monitoring systems requiring reliable performance in challenging electromagnetic environments.
