ZhengZhou STA high quality alumina NItride Substrate ceramic substrate
The aluminum nitride ceramic plate has high thermal conductivity of more than 170W/m.k,
high density, 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 highfrequency 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.
