TRF-45: Unleashing the Power of Ceramic-filled PTFE Composites

Empowering Signals: Exploring TRF-45's Impressive Dielectric Constant

When it comes to transmitting signals efficiently and maintaining signal integrity, dielectric constant plays a pivotal role. TRF-45 boasts a dielectric constant of 4.5 at 10GHz, ensuring reliable signal transmission and precise impedance control. This exceptional property enables engineers to design PCBs with superior performance and optimized signal integrity.

Dissipation Factor Demystified: How TRF-45 Ensures Signal Integrity

Signal loss can be a significant concern in high-frequency applications. TRF-45 addresses this challenge with its low dissipation factor of 0.0035 at 10GHz. By minimizing signal loss, this innovative PCB material preserves the quality and integrity of signals, allowing for seamless communication across electronic components.

Moisture Absorption: TRF-45's Contribution to PCB Stability

In humid environments, moisture absorption can compromise the performance and reliability of PCBs. TRF-45, with its moisture absorption rate of ≤0.06%, provides exceptional stability even in demanding conditions. This feature ensures that the PCB remains robust and reliable, making it suitable for a wide range of applications, including aerospace, automotive, and industrial sectors.

Flexural Strength: Unleashing TRF-45's Superior Resistance to Bending

PCBs often experience bending forces during their lifespan, which can lead to mechanical failure. TRF-45 addresses this concern with its remarkable flexural strength. With a lengthwise flexural strength of 17,000 lbs/in (177 N/mm2) and a transverse flexural strength of 15,000 lbs/in (103 N/mm2), this material exhibits exceptional resistance to bending, ensuring the longevity and durability of PCB designs.

Peel Strength: Exploring TRF-45's Robust Adhesion Properties

In PCB manufacturing, strong adhesion between layers is essential for the overall reliability of the board. TRF-45 excels in this aspect with a peel strength greater than 8 lbs/in (1.4 N/mm), as per IPC-TM-650 2.4.8 (Thermal Stress) standards. This robust adhesion ensures that the layers of the PCB remain intact, enabling the board to withstand environmental stressors and mechanical vibrations.

Keeping Cool Under Pressure: Thermal Conductivity of TRF-45

Modern electronic devices generate substantial heat, necessitating efficient thermal management within PCBs. TRF-45 exhibits a thermal conductivity of 0.43 W/m/K, as per ASTM F 433 standards. This exceptional property allows heat to dissipate effectively, preventing overheating and ensuring the optimal performance of electronic components.

Volume and Surface Resistivity: TRF-45's Contribution to Electrical Stability

Unwanted electrical leakage can disrupt the functionality of PCBs. TRF-45 addresses this concern with its volume resistivity of 8.0 x 10^7 Mohm/cm and surface resistivity of 3.0 x 10^7 Mohm, as per IPC-TM-650 2.5.17.1 standards. These values ensure a high level of electrical stability, minimizing the risk of signal degradation and maintaining the integrity of the circuit.

CTE (Coefficient of Thermal Expansion): How TRF-45 Handles Temperature Variations

Temperature variations can cause stress and strain within PCBs, potentially leading to performance issues. TRF-45 exhibits a coefficient of thermal expansion (CTE) of 9 ppm/℃ (x and y axes) and 40 ppm/℃ (z-axis), as per ASTM D 3386 (TMA) standards. This balanced CTE allows the material to adapt to thermal changes, reducing the risk of mechanical failure and ensuring long-term reliability.
