Aluminum Nitride (AlN) Sheets

Aluminum nitride (AlN) sheets, a material esteemed for its technical properties and performance in challenging environments. Our AlN sheets demonstrate a thermal conductivity greater than 200 W/mK, which is essential for applications requiring rapid and efficient heat dissipation. Coupled with a volume resistivity surpassing 1013 ohm cm, these sheets provide reliable electrical insulation, even under high temperature conditions.
With a dielectric constant of about 9 at 1MHz, and a low dielectric loss tangent (3.8×10-4), AlN sheets maintain their insulating properties across a range of frequencies, making them suitable for high frequency applications. The electric strength of the material is rated at 17 KV/mm, which allows for its use in high-voltage environments without breakdown.
The coefficient of thermal expansion of AlN sheets is matched to silicon (4.6×10-6/C), which helps to manage thermal stresses that could lead to device failure. This matching is particularly beneficial for electronic substrates, where dimensional stability is crucial for component longevity.
Aluminum Nitride Sheet Packaging
As a ceramic material, AlN material is quite fragile in a lot of cases. The aluminum nitride sheet are usually hold in plastic bags by vacuum, and protect with heavy foam.
