High Frequency PCB On DK2.65 PTFE Double Sided With OSP and
Green Mask for Combiners
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.

Soldermask is a protective layer of liquid photo-imaging paint applied
to the top and bottom of the printed circuit board. The function of the
solder mask is to protect the copper other than the pad from oxidation.
The copper layer on the green solder mask pcb is very thin, which is why
the green color stands out so much.
