0.5mm 1mm Thick Aluminum Nitride AlN Ceramic Plate

0.5mm 1mm Thick Aluminum Nitride AlN Ceramic Plate

The description of the AlN ceramic plate

AlN ceramic plate is one of the most popular technical Ceramic Substrate which offer exceptional thermal conductivity,  excellent heat resistance, high mechnical strength , abrasion resistance and small dielectric loss . The surface of AlN plate is very smooth free of porosity . The thermal conductivity of aluminum nitride , compared to alumina substrate , It is about 5 to 9 times high . AlN ceramic plate, substrate and wafer are an ideal electronic package materials . 

The specification of the AlN ceramic plate
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

6. Typical specification checklist of Aln ceramic plate as below:

The main features of the AlN ceramic plate
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 application of the AlN ceramic plate
AlN plate, wafer and 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
