Taconic TLX-9 DK2.5PTFE/Woven Glass High Frequency Laminate
Product Overview
Crafted by Taconic, a pioneer with more than 35 years of expertise in coating fiberglass fabric with polytetrafluoroethylene (PTFE), Taconic TLX-9 is a high-performance copper clad PTFE/woven glass laminate. It stands out for its ultra-precise dielectric property control—boasting a fixed dielectric constant (Dk) of 2.50 with a tight tolerance of±0.04, and an extremely low dissipation factor of 0.0019 at 10 GHz.
Engineered for dimensional stability and moisture resistance, TLX-9 laminate shows virtually no moisture absorption during manufacturing processes, ensuring consistent performance across production workflows. It is machinable with standard processing methods for PTFE/woven fiberglass materials, supporting shearing, drilling, milling, and plating operations with ease. Typically clad with 1/2, 1, or 2 oz electrodeposited copper (single or double side), custom cladding options are also available upon request. All TLX-9 substrate shipments are accompanied by a Certificate of Compliance with actual test data, all tested in accordance with the IPC-TM 650 standard.
TLX-9 DK2.5 PCB substrate is tailored for high-frequency and microwave RF applications, delivering reliable electrical, mechanical, and thermal performance in demanding scenarios such as radar systems, phased array antennas, mobile communication systems, microwave test equipment, transmission devices, and various RF passive/active components. Its UL 94 V-0 flammability rating further enhances its safety and suitability for industrial and aerospace-grade electronic designs.
