4. Core Material: TLY-3 Laminate Advantage

The 20 mil TLY-3 substrates at the heart of this Taconic RF PCB are manufactured with lightweight woven fiberglass, delivering far superior dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven matrix ensures mechanical stability, enabling high-volume manufacturing with exceptional yields. A standout feature is its ultra-low dissipation factor, which supports seamless operation in 77GHz automotive radar systems and other millimeter-wave antennas.

Comparative OEM testing at 77GHz confirms that TLY-3 matches the insertion loss and dielectric properties of competing chopped fiber materials—while offering significantly higher manufacturing yields. Its dielectric constant (Dk) ranges from 2.17 to 2.40, with a tight tolerance of±0.02 for most thicknesses. At 10GHz, the dissipation factor (Df) is as low as 0.0009, making it a top choice for high-frequency precision applications.
