This level of accuracy guarantees reliable data transfer and signal integrity, crucial for high-frequency applications. Additionally, its low loss tangent of 0.0009 at 10 GHz signifies minimal signal loss, enabling efficient transmission and reception.

2. Density and Moisture Absorption:

Weighing in at a specific gravity of 2.19 g/cm3, the TLY-5 PCB 60mil strikes the perfect balance between strength and weight. Its lightweight structure optimizes space utilization, making it ideal for compact electronic systems. Moreover, with a low moisture absorption rate of 0.02%, the PCB retains its electrical and mechanical properties even in humid environments, ensuring long-term reliability.

3. Coefficient of Thermal Expansion (CTE):

The TLY-5 PCB exhibits a CTE of 26 ppm/°C in the X-axis, 15 ppm/°C in the Y-axis, and 217 ppm/°C in the Z-axis. These balanced CTE values ensure superior dimensional stability, reducing the risk of warping or cracking due to temperature variations. This stability is vital for maintaining the integrity of the PCB in demanding environments.

4. Dimensional Stability and Copper Peel Strength:

Thanks to its woven fiberglass construction, the TLY-5 PCB offers exceptional dimensional stability. This stability minimizes any potential changes in the PCB's shape or size, ensuring reliable and consistent performance over time. Additionally, the PCB boasts high copper peel strength, enabling robust interconnectivity and reliable signal transmission.

5. Uniform and Consistent Dielectric Constant:

The TLY-5 PCB guarantees a uniform and consistent dielectric constant (DK) throughout the laminate. This uniformity eliminates any variations in signal propagation, reducing the risk of impedance mismatch and signal distortion. The result is enhanced signal integrity and improved overall performance.

6. Unraveling the Construction Details:
