When 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.
All substrates are grinded with surface roughness Ra0.3-0.6. We can also do surface polishing, one-side polishing or double-side polishing with surface roughness Ra0.02-0.05.
