Hello Everyone,
Today, we’re discussing high-frequency PCBs built on TLY materials.
TLY laminates, produced by Taconic, are made with lightweight woven fiberglass, offering superior dimensional stability compared to chopped fiber-reinforced PTFE composites. This enhanced mechanical stability makes them ideal for high-volume manufacturing.
With their low dissipation factor, TLY laminates are perfectly suited for automotive radar applications operating at 77 GHz, as well as other millimeter-wave frequency antennas. |

TLY laminates offer the following key advantages:
1. Superior Dimensional Stability:
Supports high-volume manufacturing with consistent results.
2. Ultra-Low Dissipation Factor:
A DF of ~0.0009 at 10 GHz minimizes signal loss in low-Dk applications.
3. Excellent Moisture Resistance:
Performs reliably in challenging environments, ensuring long-term stability.
4. High Copper Peel Strength:
With a peel strength of up to 2.32, it provides robust mechanical integrity.
5. Tight DK Tolerance:
A dielectric constant tolerance of +/-0.02 ensures uniformity and consistency across the board. |
