PTFE High Frequency PCB On DK2.65 Double Sided Cheap Teflon RF PCB for Combiners
(Printed Circuit Boards are custom-made products, the picture and
parameters shown are just for reference)
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.
Polytetrafluoroethylene (F4,PTFE) has a series of excellent
performance:
1.high temperature resistance: long-term use temperature 200~260
degrees Celsius.
2.low temperature resistance: still soft at -100 degrees Celsius;
3.corrosion resistance: resistant aqua regia and all organic
solvents;
4.climate resistance: best aging life in plastics;
5.high lubrication: with the smallest friction coefficient in
plastics (0.04);
6.Non-viscous: with minimal surface tension in solid materials
without adhering to any substance;
7.non-toxic: with physiological inertness;
8.excellent electrical properties, ideal for C class of insulating
materials, a thick layer of stack of newspaper can block 1500 V of
high voltage;
9.smoother than ice.
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.
