PTFE High Frequency PCB Built on 2oz Copper 1.6mm Thick With Immersion Gold for Duplex
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:
Withstands Extreme Temperatures: Performs reliably in both intense heat (up to 260°C) and severe cold (down to -100°C).
Unmatched Chemical Resistance: Impervious to even the harshest chemicals, such as aqua regia, and all organic solvents.
Superior Weathering: Exceptional resistance to degradation from sunlight and ozone, giving it the longest service life of any plastic.
Exceptionally Slippery: Has the lowest friction coefficient of any known plastic (0.04), providing a self-lubricating surface.
Perfect Non-stick Qualities: Its ultra-low surface tension ensures almost nothing sticks to it.
Safe and Inert: Non-toxic and biologically compatible, making it suitable for medical and food applications.
Outstanding Electrical Insulator: Serves as an ideal Class C insulating material, capable of withstanding high voltages with minimal thickness.
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.
