Taconic RF PCB Made on TLF-35 60mil 1.524mm With
Immersion Gold for Mixer, Filters and Couplers etc.
TLF-35A has excellent peel strength for 1/2
ounce and 1 ounce copper (even in comparison to standard epoxy materials), a
critical aspect whenever rework is required.
The ultra low moisture absorption rate and low
dissipation factor of TLF-35A minimizes phase shift with frequency. TLF-35A is
dimensionally stable due to the use of woven fabrics in its design. TLF-35A
base materials exhibit flammability of V-0, and are tested in accordance with IPC-TM-650.
TFL-35A has low dielectric constant at 3.5
+/-0.05, low dissipation factor at 0.002.
Benefits:
Low cost
Excellent peel strength
Exceptionally low DF
Low moisture absorption
Very high thermal reliability
Applications:
Filter, coupler, splitter, combiner and mixer
Antenna
High power Amplifier, TMA, TMB, LNA
Repeater
Passive components
Medical scanners
