Overview of TLY-5 Laminates
The foundation of the TLY-5 PCB lies in its advanced laminate composition. Manufactured from lightweight woven fiberglass, TLY-5 offers superior dimensional stability compared to conventional chopped fiber reinforced PTFE composites. This stability is critical for high-volume manufacturing, where consistency and reliability are paramount.
Key Material Characteristics
Dielectric Constant (Dk): With a value of 2.2 and a tight tolerance of ±0.02 at 10 GHz/23°C, the TLY-5 PCB ensures minimal signal loss and exceptional performance in high-frequency environments.
Loss Tangent (Df): At just 0.0009 at 10 GHz, the low dissipation factor contributes to high signal integrity, making it ideal for applications requiring precision.
Moisture Absorption: A moisture absorption rate of only 0.02% minimizes the risk of performance degradation over time, particularly in humid environments.
Benefits of TLY-5 PCB
1. Dimensionally Stable
One of the most significant advantages of the TLY-5 PCB is its dimensional stability. This characteristic ensures that the board maintains its integrity under varying environmental conditions, reducing the risk of warping or deformation during manufacturing or operation.
2. Low Dissipation Factor
The low DF of the TLY-5 PCB enhances signal integrity, making it suitable for high-frequency applications where even minor losses can lead to significant performance issues. This feature is crucial for automotive radar systems and millimeter wave antennas.
3. Low Moisture Absorption
The minimal moisture absorption of the TLY-5 PCB protects against performance degradation. This characteristic is especially beneficial in outdoor applications or environments with fluctuating humidity levels.
4. High Copper Peel Strength
The TLY-5 PCB boasts high copper peel strength, ensuring durability and reliability in demanding applications. This feature is essential for ensuring that the conductive layers remain intact under mechanical stress.
5. Uniform Dielectric Constant
The consistent dielectric constant across the board allows for predictable performance, which is vital for applications requiring precision in signal transmission.
