    What Is Multilayer Fr4 PCB Substrate Material? - RayPCB
    TU-872 SLK is a high-performance modified epoxy resin FR-4 material, manufactured by TUC, designed for high-speed, low-loss, and high-frequency multilayer PCB applications. It features excellent thermal reliability, low dielectric constant (Dk), low dissipation factor (Df), and is compatible with lead-free soldering processes. 
    Key Characteristics of TU-872 Multilayer PCBs 
    • Material Composition: Modified epoxy resin reinforced with woven E-glass (FR-4).
    • Low Dk/Df: Designed for superior signal integrity in high-frequency applications, minimizing signal loss.
    • Thermal Performance: High thermal reliability and stability.
    • CAF Resistance: Excellent Conductive Anodic Filament (CAF) resistance, enhancing reliability in humid environments.
    • Processing: Compatible with standard FR-4 fabrication processes, making it a drop-in replacement for high-speed upgrades. 
    Applications 
    Due to its low-loss characteristics, TU-872 is widely used in: 
    • High-speed computing and servers.
    • Telecommunication systems.
    • High-frequency multilayer circuit boards.
    • Aerospace and industrial controls requiring high reliability. 
    Typical Technical Specifications (TU-872 SLK/LK) 
    • Tg (Glass Transition Temp): Typically
      >170∘
      𝐶
       (Mid-Tg to High-Tg).
    • Df (Dissipation Factor): Low, improving high-frequency performance.
    • Dk (Dielectric Constant): Stable and low.
    • Flammability: UL 94V-0. 
    TU-872 SLK/LK provides a robust, cost-effective solution compared to PTFE-based materials, offering high-speed performance within standard FR-4 manufacturing limitations.
