Unleashing the Power of RF-35 High Frequency PCB: Next-Level
Substrate Technology
Introduction:
In the realm of high-frequency applications, performance and
reliability reign supreme. Enter the RF-35 High Frequency PCB, a
revolutionary solution born from Taconic's expertise in coated PTFE
fiberglass and ceramic fill technologies. Get ready to witness the
game-changing capabilities and exceptional construction of RF-35,
setting a new benchmark in high-frequency substrate technology.
Discover the RF-35 Substrate:
Let's delve into the extraordinary properties that make RF-35 a
true industry disruptor. Operating at 1.9 GHz, it boasts an
impressive dielectric constant of 3.50, accompanied by an ultra-low
dissipation factor of 0.0018. With a moisture absorption rate as
low as 0.02% at .060 inch, RF-35 guarantees unwavering stability,
even in the harshest environments.
Uncompromising Strength and Stability:
RF-35 goes above and beyond when it comes to mechanical robustness
and dimensional stability. It exhibits an exceptional peel strength
of over 8.0 lbs./linear inch for 1/2 oz. copper and exceeds 10.0
lbs./linear inch for 1 oz. copper, as verified by IPC-TM 650 2.4.8
standards. With an arc resistance surpassing 180 seconds, as per
IPC TM 650 2.5.1, RF-35 ensures steadfast performance under the
most demanding conditions.
Exceptional Thermal Management:
Equipped with a high Tg value surpassing 315°C, RF-35 excels at
thermal management. Its impressive thermal conductivity of 0.24
W/m/K, measured by ASTM F 433, effectively dissipates heat,
guaranteeing optimal performance for power amplifiers, passive
components, filters, and couplers.
Precision Machining Considerations:
Machining PTFE-based substrates can present unique challenges due
to the softness of the PTFE resin system. RF-35 employs a
heavyweight 7628 glass style, offering outstanding dimensional
stability and rigidity. However, achieving precise drilling and
routing may require specialized expertise due to the heavier
fiberglass weave.
Conclusion:
The RF-35 High Frequency PCB epitomizes our unwavering commitment
to delivering top-notch product quality and fostering trust. Its
exceptional characteristics, including minimal dielectric loss,
high peel strength, and superior thermal management capabilities,
position it as the ultimate choice for high-frequency applications.
Experience the unparalleled power of RF-35 and unlock new realms of
possibility in your high-frequency designs. Rely on our dedication
to providing cutting-edge solutions that not only meet but exceed
your expectations.
