How Does TRF-45 PCB Material Ensure Reliability in Demanding High-Frequency Designs?

In the demanding world of high-frequency electronics, the choice of printed circuit board (PCB) substrate is a critical determinant of performance, reliability, and ultimate product success. Engineers and designers continually seek materials that offer minimal signal loss, exceptional thermal stability, and straightforward manufacturability. Meeting these rigorous demands,TRF-45 high-frequency materials emerge as a premier solution, representing a significant breakthrough in low-loss, thermally stable PCB substrates. This advanced material leverages Taconic's profound expertise in ceramic technology to deliver unparalleled performance across a wide spectrum of applications.

Superior Material Properties for Demanding Environments

At the core of the TRF-45 substrate 's success is its unique composition, which incorporates a woven-glass reinforcement. This structure grants the substrate superior dimensional stability, a vital characteristic for maintaining circuit integrity under thermal stress. A key differentiator forTaconic TRF-45 is its reliably low Z-axis coefficient of thermal expansion (CTE), which it maintains consistently across a broad temperature range, including during the high-heat soldering process. This property is crucial for preventing plated through-hole failure in multilayer boards, ensuring long-term reliability.

The electrical properties of TRF-45 are equally impressive, making it an ideal candidate for high-speed digital and RF/microwave applications. It boasts a stable dielectric constant (Dk) of 4.5 at 10 GHz, providing predictable electrical behavior for precise impedance control. Coupled with an exceptionally low dissipation factor (Df) of 0.0035 at the same frequency, TRF-45 ensures minimal signal attenuation, preserving signal integrity even at high frequencies.

Further enhancing its robustness, TRF-45 exhibits an extremely low moisture absorption rate of≤0.06%, demonstrating exceptional resistance to humid environments. This, combined with a high flexural strength of 17,000 lbs/in (lengthwise) and 15,000 lbs/in (transverse), ensures mechanical durability. The material delivers outstanding peel strength, exceeding 8 lbs/in, which guarantees strong adhesion between the copper and substrate. Its CTE values—9 ppm/°C on the X and Y axes and 40 ppm/°C on the Z-axis—contribute to excellent thermal dimensional stability. Finally, its UL-94 V0 certification confirms its flame-retardant properties, meeting critical safety standards.

Seamless Integration into Standard PCB Fabrication

A significant advantage of TRF-45 PCB is its compatibility with standard PCB fabrication processes. Unlike some high-performance materials that require specialized equipment or techniques, TRF-45 can be processed using the same conventional methods applied to PTFE woven fiber-glass materials. This includes standard shearing, drilling, milling, and plating operations, which helps streamline production, reduce lead times, and control costs without compromising on the superior performance characteristics of the final product.
