Product Description

Thin Flim High Thermal Conductivity Aluminum Nitride AlN Ceramic Wafer

The specification of the AlN Ceramic wafer

1. We are supplying with many round ceramic wafers, square & rectangular ceramic substrates
2. The typical thickness of AlN wafers covers 0.38mm, 0.5mm, 0.635mm, 1.0mm, 1.2mm, 1.5mm
3. The biggest diameter of the round ceramic wafer can be up to 400mm in 3mm, 4mm, 5mm thick
4. The max. side-length of  the square and rectangular ceramic wafer can be 400mm by 500mm
5. Surface treatment: it can be one-side, or double side polished, metalizing or sandblasting
The main features of the AlN ceramic wafer
1. High thermal conductivity (170 ~220) W/m.k, it's 5~8.5 times higher than that of alumina
2. Similar coefficient of thermal expansion to that of silicon (Si), it helps to achieve high reliability of Si chip
3. High insulation resistance and voltage resistance strength, but low dielectric constant and dielectric loss
4. High mechanical strength, it's up to 450MPa and very dense ceramic body free of porosity
5. It offers very high purity up to 99%, also it's free of toxicity and meets RoHS, REACH regulation

The description of the AlN ceramic wafer
Our facility has been manufacturing aluminum nitride (AlN) wafers for ages, including a selection of thickness from 0.30mm to 10mm.

With both extremely high thermal conductivity (170-220W/mK) and insulating properties. These ceramic wafers can be the best solution in electronics applications where strict conditions are required, such as power modules (MOSFET, IGBT), LED packages for protecting circuits, cooling, packages, and modules.
