We are delighted to share a type of new variant of TLY-5 PCBs, a lightweight solution that revolutionizes high-frequency RF and microwave applications by delivering unmatched levels of performance and reliability.

Introduction to TLY-5:
TLY-5 laminates are manufactured using lightweight woven fiberglass and offer superior dimensional stability compared to chopped fiber reinforced PTFE composites. The woven matrix in TLY-5 material provides mechanical stability, making it ideal for high volume manufacturing. With its low dissipation factor, TLY-5 enables successful deployment in automotive radar applications operating at 77 GHz and other millimeter wave frequency antennas.

Key Features:
Dielectric constant of 2.2 with a tight tolerance of 0.02 at 10 GHz/23°C.
Low loss tangent of 0.0009 at 10 GHz.
Density (specific gravity) of 2.19 g/cm3.
Moisture absorption of 0.02%.
Coefficient of Thermal Expansion (CTE): X-axis - 26 ppm/°C, Y-axis - 15 ppm/°C, Z-axis - 217 ppm/°C.

Benefits:
Excellent dimensional stability.
Lowest dissipation factor (DF).
Low moisture absorption.
High copper peel strength.
Uniform and consistent dielectric constant (DK).
