What is the Taconic TLY-3 laminate?

TLY-3 laminates are fabricated using ultra-lightweight woven fiberglass, exhibiting significantly greater dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven structure of TLY-3 enhances its mechanical stability, making it highly suitable for high-volume manufacturing processes. Its low dissipation factor ensures successful implementation in automotive radar applications operating at 77 GHz, as well as other antennas within millimeter-wave frequencies.

TLY-3 offers a compelling solution for tackling the challenges of high-frequency applications. Comparative OEM testing at 77 GHz of lightly reinforced TLY-3 vs. its closest chopped fiber reinforced competitor has shown “drop in”/equivalent insertion losses/dielectric properties. The primary advantage lies in achieving significantly higher manufacturing yields. The dielectric constant ranges from 2.17 to 2.40, with most thicknesses allowing specification anywhere within this range, maintaining a tolerance of ±0.02. In the lower dielectric constant range, the dissipation factor is approximately 0.0009 at 10 GHz. Typical applications encompass satellite communications, automotive radar, filters, couplers, avionics, and phased array antennas.

TLY-3FF represents a highly flexible laminate tailored for applications requiring installation with a defined bend radius. It surpasses standard TLY-3 fiberglass-reinforced substrates in flexibility while maintaining superior dimensional stability. The flexibility of TLY-3FF rivals that of chopped fiber-reinforced PTFE laminates but features a lower loss tangent. TLY-3FF has been specifically engineered to combine the dimensional stability characteristic of the standard fiberglass-reinforced TLY-5 Series with enhanced laser via formation capabilities relative to traditional TLY-3 glass-reinforced laminates.

Features of the Taconic TLY-3 laminate

Consistent Dielectric Constant (Dk)

The stable dielectric constant ensures predictable signal performance, which is critical for high frequency applications. This consistency minimizes signal distortion, enhancing overall circuit performance. TLY-3 laminates maintain a stable dielectric constant across a broad frequency range, ensuring predictable signal integrity and minimal impedance variations. This is crucial for high-speed and high-frequency designs.

Lowest Dissipation Factor (Df)

With an ultra-low dissipation factor, TLY-3 minimizes signal loss and heat generation, making it ideal for high-power and high-frequency applications where efficiency is paramount. With a minimal dissipation factor, these laminates reduce energy losses during signal transmission, resulting in higher efficiency and improved performance, particularly in microwave and RF applications.

High Peel Strength

The robust adhesion between layers contributes to excellent mechanical integrity. This high peel strength ensures durability and reliability, even in environments subject to thermal cycling or mechanical stress. The material’s exceptional bond strength between copper and substrate ensures durability, even in harsh environments subject to thermal cycling or mechanical stress.

Low Moisture Absorption

The laminates’s resistance to moisture absorption 0.02% prevents performance degradation in humid conditions, maintaining electrical stability over time. By resisting moisture uptake, The laminates maintain their electrical properties and dimensional stability.
