The Taconic TLF-35 RF Printed Circuit Board is a custom-made
product that provides high-frequency capabilities for a variety of
commercial microwave and radio frequency applications. With a
thickness of 60mil (1.524mm) and immersion gold plating, the TLF-35
PCB is designed to provide excellent peel strength for 1/2 ounce
and 1 ounce copper, which is particularly important for rework
purposes.
One of the key features of the TLF-35 PCB is its ultra-low moisture
absorption rate and low dissipation factor, which minimizes phase
shift with frequency. Additionally, the use of woven fabrics in its
design ensures that the TLF-35 PCB is dimensionally stable. The
base materials of the TLF-35 PCB exhibit flammability of V-0 and
are tested in accordance with IPC-TM-650.
