    AI Overview
    TU-768 is a high-Tg (
    ≥170∘Cis greater than or equal to 170 raised to the composed with power C
    ≥170∘C
    ), high-reliability FR-4 epoxy laminate and prepreg from TUC, designed for Lead-Free soldering and severe thermal cycling. It features
    180∘C180 raised to the composed with power C
    180∘C
     Tg (DSC), low Z-axis CTE (2.7% @
    50
    −260∘C
    ), and superior CAF resistance. Typical applications include automotive, servers, and high-performance, multilayer/HDI PCBs. 
    Key Features and Specifications 
    • High Thermal Reliability: The material offers a
      Tdcap T sub d
      𝑇𝑑
       (decomposition temperature) of
      340∘C340 raised to the composed with power C
      340∘C
      , maintaining stability in high-heat, lead-free environments.       
    • Thermal Expansion (CTE): Low Z-axis expansion of 2.7% (
      50
      −260∘C
      ) ensures through-hole reliability, while X/Y axis CTE is
      11
      −15
      ppm/∘C
      .       
    • Electrical Properties: It has a dielectric constant (
      Dkcap D sub k
      𝐷𝑘
      ) of approximately 4.3–4.4 and a loss tangent (
      Dfcap D sub f
      𝐷𝑓
      ) of 0.023 at 10 GHz.       
    • CAF Resistance: Excellent Conductive Anodic Filamentation (CAF) resistance, crucial for high-density automotive designs. 
    • Manufacturing Capability: Supports multilayer and HDI technology, with a typical thickness ranging from
      0.5
      mm
       to
      3.2
      mm
       and copper weights up to 3oz.       
    Common Applications 
    • Automotive: Engine control units, ADAS, and high-temperature environments.
    • Computing: Servers, workstations, and high-density data storage devices.
    • Communication: Telecommunication equipment and high-frequency, high-speed digital systems. 
    For detailed material specifications and to verify design compliance, you can refer to the official TU-768 datasheet from TUC or this TI E2E forum thread. The material is also discussed in the TU-768 High-Tg article.
