Advantages of AlN Materials:
AlN is the best ceramic packaging and heat sink material, with its high thermal conductivity, hardness, insulation and low coefficient of thermal expansion. And its thermal expansion coefficient is similar with sillicon, so AlN ceramic substrate is widely used in communication components, high power LED, power electronic devices, high power lasor diode and other fields.
Properties of AlN Ceramic Substrate:
High thermal conductivity
High flexural strength
High temperature
Good electrical insulation
Low dielectric constant and loss
Able to be laser drilled, metallized, plated and brazed
