Aluminum Nitride Ceramic Substrate
LT1800 Aluminum nitride conductive ceramic sheet has high thermal conductivity 180W/m-k,one of the highest thermal conductivitymaterials in metallic materials (7~10 times of alumina ceramic sheet). Excellent mechanical properties, good processing, highprecision, smooth surface, no microcracks, bending, etc. Low dielectric constant and dielectric loss, reliable electricalinsulation performance. Non-toxic, high temperature of 1800 degrees, oil resistant, chemical resistant, and similar to the thermalexpansion coefficient of silicon, without hygroscopic property, stable performance and high reliability in high temperature andhigh humidity. Along with the microelectronic devices, the extensive development of the microelectronic equipment, the highthermal conductivity nitride ceramic sheet is widely valued and applied.Application: abrasion resistant lining patch; patch type electronic component substrate; computer accessories.
strong current, strong voltage, high temperature and easy wear parts of electronic appliances and mechanical equipment.
Physical properties: insulation, shock resistance, high temperature resistance, wear resistance, high strength
