The specification of the AlN Ceramic Substrate
1. We are supplying with many round ceramic wafer, square & rectangular ceramic substrate
2. The typical thickness of wafer covers 0.38mm, 0.5mm, 0.635mm, 1.0mm, 1.2mm, 1.5mm
3. The biggest diameter of round ceramic wafer can be up to 400mm in 3mm, 4mm, 5mm thick
4. The max. side-length of square and rectangular ceramic wafer can be 400mm by 500mm
5. Surface treatment: it can be one-side, or double side polished, metalizing or sand blasting
The main features of the AlN ceramic substrate
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 substrate
The aln ceramic substrate which has high thermal conductivity of more than 170W/m. K, high resistivity, low dielectric loss, good insulation and some other excellent properties. The ALN substrate is the best choice for a wide range of industrial insulating heat sink material of high power machinery and equipments such as high-frequency equipment substrate, high power transistor module substrate, high-density hybrid circuits, microwave power devices, power semiconductor devices, power electronic devices, optoelectronic components, laser-semi-conductor, LED, IC products, and so on.
AlN substrate can be the best solution in electronics applications where strict conditions are required, such as power modules (MOSFET, IGBT), LED packages for cooling and protecting circuits, packages and modules.
The application of the AlN ceramic substrate
AlN wafer adn substrate is an excellent electronic package material, AlN substrate for a wide range of applications,
including thin film and thick film microelectronic , high power and high frequency circuit RF / microwave components and capacitor or resistor
Remark:
We supply a broad range of ceramic wafers, including Alumina Ceramic wafer, zirconia ceramic wafer,
silicon nitride ceramic wafer, aluminum nitride ceramic wafer and so on.
