The low dielectric constant aln ceramics substrate which has high thermal conductivity of more than
170W/m.k, high density, low dielectric loss, good insulation and some other excellent properties.
The ALN disk is the best choice for a wide range of industrial insulating heat sink material of high
power machinery and equipments such as highfrequency equipment substrate, high power
transistor module substrate, high density hybrid circuits, microwave power devices, power
semiconductor devices, power electronic devices, optoelectronic components, laser semiconductor,
LED, IC products, and so on.
Surface roughness can be reached within 0.1µm after being polished. Size tolerance can be controlled
at around ±0.1mm by laser machine.
Different dimension and thickness are available via laser cutting or customize.
