Aluminum Nitride Ceramic Substrate
Aluminum Nitride (AlN) Ceramic Substrates: The Ultimate Thermal Solution for High-Power & High-Frequency Electronics
Aluminum Nitride (AlN) ceramic substrates represent the pinnacle of performance in advanced circuit board materials. Specifically, our AlN-96 grade (96% purity) offers an exceptional balance of ultra-high thermal conductivity and excellent electrical insulation, making it the material of choice for the most demanding electronic applications where heat is the primary enemy of reliability and efficiency.
Why Choose Our Aluminum Nitride Substrates?
- Unmatched Thermal Management
With a thermal conductivity of 170–200 W/(m·K), AlN-96 dissipates heat up to 10 times faster than conventional alumina (Al₂O₃). This effectively lowers junction temperatures and dramatically enhances the performance, lifespan, and reliability of power devices such as LEDs, laser diodes, and IGBT modules. - Excellent Electrical Insulation
AlN exhibits high electrical resistivity and low dielectric loss, ensuring stable signal integrity and effective electrical isolation in high-frequency circuits. - Coefficient of Thermal Expansion Matching Silicon
Its CTE closely matches that of silicon chips, significantly reducing thermal stress at the chip-attach interface and preventing solder joint failure during power cycling. - High Mechanical Strength & Stability
AlN ceramics maintain structural integrity and stable performance under extreme thermal and mechanical stress, ensuring long-term durability.
