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.
