PTFE High Frequency PCB Built on DK2.65 1.6mmTeflon With Immersion Gold for Couplers


Polytetrafluoroethylene (Short for PTFE), commonly known as "plastic king ", is a polymer compound made of tetrafluoroethylene by polymerization. It has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-viscosity, electrical insulation and good aging resistance. Used as engineering plastic, it can be made into PTFE tube, rod, belt, plate, film and so on. Generally it’s used in high performance requirements of corrosion-resistant pipes, containers, pumps, valves as well as radar, high-frequency communication equipment, radio equipment.


Excellent performance:

  • high temperature resistance: long-term use temperature 200~260 degrees Celsius.
  • low temperature resistance: still soft at -100 degrees Celsius;
  • corrosion resistance: resistant aqua regia and all organic solvents;
  • climate resistance: best aging life in plastics;
  • high lubrication: with the smallest friction coefficient in plastics (0.04);
  • Non-viscous: with minimal surface tension in solid materials without adhering to any substance;
  • non-toxic: with physiological inertness;
  • excellent electrical properties, ideal for C class of insulating materials, a thick layer of stack of newspaper can block 1500 V of high voltage;
  • smoother than ice.



F4BM-1/2 High Frequency PCB

F4BM-1/2 is laminated by laying up of varnished glass cloth with Teflon resin, according to the scientific formulation and strict technology process. This product takes some advantages over F4B series in the electrical performance(wider range of dielectric constant,lower dielectric loss angle tangent,increased resistance,and more stability of performance)


At RF and Microwave frequencies, the dielectric constant of PTFE materials is as low as 3.5 or below, which keeps strong signal during transmission across PCB, making them ideal for overcoming the high speed limitation of FR-4.
