: High Thermal ConductivityWhen it comes to providing good thermal conductivity and high electrical insulation features, aluminum nitride substrate is a superb option because of its efficacy. Aluminum nitride sheets are widely used in the semiconductor application industry instead of beryllium oxide (BeO) since aluminium nitride is non-toxic and does not produce dangerous vapors when grinded and machined. Aluminum nitride ceramic substrate has a thermal expansion and isolation coefficient which closely matches the silicon wafer product, making it useful in applications in electronics that often have high temperatures and heat dissipation problems.
