Taconic RF PCB Made on TLF-35 60mil 1.524mm With Immersion Gold for Mixer, Filters and Couplers etc.
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
TLF-35A is another type of low cost RF material. It's the best choice for low cost, high volume commercial microwave and radio frequency applications. 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.
