Materials for RF laminates constructed on Taconic RF-35TC PCB Manufacturer 30 mil 0.762 mm
with black solder mask for antennas
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RF-35TC from Taconic company sets a benchmark in high-frequency materials, offering an unparalleled low
dissipation factor coupled with high thermal conductivity. Tailored for high-power applications where even a
tenth of a decibel is critical, this material excels in diffusing heat away from transmission lines and surface
mount components like transistors.
Crafted from a PTFE-based composition, RF-35TC features a ceramic-filled fiberglass substrate. Unlike its
hydrocarbon counterparts, it remains resistant to oxidation, yellowing, and the upward drift in dielectric constant
and dissipation factor over time.
With a low dielectric constant of 3.50 and an exceptionally low Df of 0.0011, this laminate ensures minimal
signal loss and efficient heat dissipation. Its strong bond with low-profile copper further minimizes insertion
loss, enhancing overall performance.
RF-35TC laminates find their optimal use in diverse applications such as antennas, satellites, filters, couplers,
and power amplifiers, where reliability, thermal management, and high performance are of paramount importance.
