DK2.65 F4B PTFE Based 1.6mm High Frequency PCB Black Solder Mask
Circuit
Polytetrafluoroethylene (PTFE), also referred to as "plastic king,"
is a polymer compound created by polymerizing tetrafluoroethylene.
Excellent chemical stability, corrosion resistance, sealing, high
lubrication, low viscosity, electrical insulation, and strong aging
resistance are only a few of its many strengths. It can be produced
into PTFE tube, rod, belt, plate, film, and other engineering
plastic products. It is typically utilized in high performance
requirements for corrosion-resistant pipelines, containers, pumps,
valves, radar, high-frequency communication equipment, and radio
equipment.
By laminating varnished glass cloth with Teflon resin, F4BM-1/2 is
laminated in accordance with a precise technological procedure and
scientific formulation. Compared to the F4B series, this product
has some advantages in terms of electrical performance (wider range
of dielectric constant,lower dielectric loss angle
tangent,increased resistance,and more stability of performance).
The dielectric constant of PTFE materials is as low as 3.5 or lower
at RF and microwave frequencies, which maintains a strong signal
while transmission across PCB and makes them the perfect solution
for getting around FR-4's high speed restriction.
