Aluminum Nitride Ceramic Heat-Sink for LED Lighting Systems¹

Product Description Aluminum Nitride Ceramic Heat-sink for LED Lighting SystemsProduct Description1. High thermal conductivity (170 ~220) W/m.k,  it's 5~8.5 times higher than that of alumina2. Similar coefficient of thermal expansion to that of silicon (Si), it helps to achieve high reliability of Si chip3. High insulation resistance and voltage resistance strength, but low dielectric constant and dielectric loss4. High mechanical strength, it's up to 450MPa and very dense ceramic body free of porosity5. It offers very high purity up to 99%, also it's free of toxicity and meets RoHS, REACH regulationThe specification of ceramic wafers and substrateMaterial Aluminum nitride (AlN), alumina(al2o3), zirconia(ZrO2), silicon nitride(Si3N4), silicon carbide(SiC) Color Gray, black, white, pink, ivory, yellowish are available Typical thickness 0.385mm, 0.50mm, 0.635mm, 1.0mm, 1.2mm and 1.5mm Dimensional capability Max. side-length to be 500mm by 400mm, Max OD to be 400mm Tolerance  OD can be ± 0.01mm, Thickness can be ± 0.005mm Surface treatmentnatural surface, lapping, diamond-like polishing, metallization, glazed Remark:We produce a selection of ceramic wafers in different materials, customized designs, including alumina ceramic wafers, zirconia ceramic wafers, silicon nitride ceramic wafers, and silicon carbide wafers.The description of the AlN ceramic heat sinkThe aluminum nitride ceramic sink heat offers a super high thermal conductivity of more than 170W/m. K, high resistivity, low dielectric loss, good insulation, and some other excellent properties. The ALN wafer is the best choice for a wide range of industrial insulating heat sink material of high power machinery and equipment 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.Typical ApplicationsWhy choose us?1. 10+ Years of manufacturing experience in OEM, ODM, and trusted & professional teams2.
