    AI Overview
    Dry pressed Aluminum Nitride (AlN) heat sinks are advanced ceramic thermal management components valued for their high thermal conductivity, electrical insulation, and CTE (Coefficient of Thermal Expansion) matching silicon, making them ideal for high-power electronics and 5G applications. Dry pressing allows for the cost-effective production of dense, high-purity components, such as ceramic discs, substrates, and sheets. 
    Key Properties 
    • High Thermal Conductivity: Typical thermal conductivity ranges between
      100
      −320
      W/m
      ⋅K
      , often 5-10 times higher than aluminum oxide (alumina).
    • Electrical Insulation: High electrical resistivity ensures superior insulation while dissipating heat.
    • Thermal Expansion Match: The CTE is similar to Silicon (
      Sicap S i
      𝑆𝑖
      ), minimizing thermal fatigue in power devices.
    • Thermal Shock Resistance: Excellent stability during rapid heating and cooling cycles.
    • Forming Technique: Dry pressing followed by sintering produces stable, dense shapes. 
    Applications 
    • High-Power Electronics: Used as substrates or heat spreaders for IGBTs, MOSFETs, and laser diodes (LD).
    • LED Cooling: High-power LED packaging substrates.
    • Semiconductor Manufacturing: Ideal for high-temperature, high-pressure environments, including wafer processing.
    • 5G Communication: Used in high-frequency power components. 
    Product Options 
    • Sheets & Discs: Commonly available in various sizes (e.g.,
      50
      mm
      ×50
      mm
      ) and thicknesses, with options for copper coating on one or both sides.
    • Customization: Components can be produced to specific, high-precision drawings.
    • Thermal Pads: Available for specialized applications like TO-247 or TO-264 transistor packages. 
    To give you the most relevant information on dry pressed AlN heat sinks, could you tell me:
    • What is the application or device you are trying to cool (e.g., LED, IGBT, laser)?
    • Do you require a standard sheet/sheet or custom machined shape?
    • What is your estimated quantity for this project?
