Introduction to TU-768

The TU-768 and its variant, TU-768P, are manufactured using high-quality woven E-glass combined with an advanced epoxy resin system. This unique composition not only grants UV-blocking properties but also ensures compatibility with automated optical inspection (AOI) processes. The TU-768 is specifically designed for applications that endure severe thermal cycles or extensive assembly work, making it a versatile and reliable choice for engineers and manufacturers alike.

Key Characteristics of the TU-768 PCB

Thermal Stability and Resistance

One of the standout features of the TU-768 is its high glass transition temperature (Tg) of 180°C. This characteristic is crucial for applications that require the PCB to withstand high temperatures without compromising performance. The laminate's excellent coefficient of thermal expansion (CTE), with values of 11-15 ppm/°C in both X and Y axes, ensures dimensional stability, minimizing the risk of warping or delamination during thermal cycling.

Compatibility and Reliability

The TU-768 is fully compatible with lead-free processes, aligning with current manufacturing trends and environmental regulations. Its superior chemical resistance and anti-conductive anodic filament (CAF) properties further enhance its reliability, making it suitable for high-density applications where performance and longevity are critical.

Low Loss Characteristics

With a dielectric constant (Dk) of 4.3 at both 5 GHz and 10 GHz, and a loss tangent (Df) as low as 0.018 at 1 GHz, the TU-768 PCB demonstrates excellent signal integrity. This low-loss performance is essential for high-frequency applications, where signal degradation can significantly impact overall system performance.
