TLY-5 PCB Material Copper Clad Laminate

TLY-5 laminates are fabricated using ultra-lightweight woven fiberglass substrates, delivering superior dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven fiber matrix inherent to TLY-5 imparts enhanced mechanical robustness to the laminate, rendering it well-suited for high-volume production environments. Boasting a low dissipation factor, this material is ideally engineered for 77 GHz automotive radar systems and a broad spectrum of other millimeter-wave antenna applications.

Comparative OEM validation testing conducted at 77 GHz—pitting lightly reinforced TLY-5 against its closest chopped fiber-reinforced counterpart—has verified drop-in compatibility, with equivalent insertion loss and dielectric performance metrics. The key competitive advantage lies in TLY-5’s substantially higher manufacturing yields.

TLY-5 features a dielectric constant (Dk) range of 2.17–2.40. For the majority of available thicknesses, the Dk value can be customized to any point within this interval, with a tight tolerance of ±0.02. At 10 GHz, the material exhibits a dissipation factor (Df) of approximately 0.0009, a standout performance within the low-Dk material category.
