Taconic's RF-35 long laminates provide antenna manufacturers with cost advantage.
In less than one year after commercializing its low cost PTFE/glass fabric
base material RF-35 in standard sheet sizes of 36 x 48 " (914 x 1220 mm),
Taconic can now offer RF-35 also in long laminate formats for long PCS/PCN
antennas. The unique capability for trimmed sheet sizes of 36 x 60" (914 x
1526 mm), 36 x 76" (914 x 1930 mm), and 102" (2590 mm) is key for
companies involved in design and manufacture of base station antennas of
typical thicknesses of 0.0300" (0.76 mm) and 0.0600" (1.52 mm).
RF-35 was engineered combining Taconic's advanced knowledge of PTFE/glass
fabric technology with ceramic-fill technology to produce base material
with a DK of 3.5 for microwave, RF and High Speed Digital printed circuit
boards. This ensures the best-of-class tolerances for thickness and dielectric
consistency.
Ultra-low moisture absorption of RF-35 (less than 0.02 %) coupled with a low
dissipation factor of 0.0018 (measured at 1.9 GHz) aid in limiting the amount
of signal amplification required, reducing signal noise, and minimizing phase
shift with frequency.
RF-35 has the highest available copper peel strength for base materials with
a dielectric constant of 3.5: 8 lbs./in (1.4 N/mm) for ½ ounce (17.5 µm)
copper, and > 10 lbs./in (1.75 N/mm) for 1 ounce (35 µm) copper cladding.
This ensures reliability over time, and greater ease and resilience in
assembly, in particular during rework operations.
RF-35 laminates exhibit V-0 flammability according to UL94, and are tested
in accordance with IPC-TM-650.
Taconic manufactures PTFE/glass fabric base materials for microwave, RF and
High-Speed Digital applications in both Petersburgh (NY, USA) and Mullingar
(Ireland). To request additional information regarding RF-35 long laminates
or any other Taconic base material, please contact the
Taconic Customer Service Department.
