Product Description Laser Processing Aluminum Oxide Plate 96% Al2O3 Alumina Ceramic SubstrateProduct IntroductionThe Differences Between Ceramic Substrates and Traditional PCB Boards1. Different materials.Most of the ceramic bases used in ceramic substrates are alumina, aluminum nitride or silicon nitride ceramics, which are inorganic materials. Traditional PCB boards use FR4 glass fiber boards, which are organic materials.2. Different production process, cost and lead time.The ceramic substrate is fragile and cannot be pressed together. And because of its high hardness and density, the production process is much more difficult than the traditional PCB board, and the requirements for the technology are relatively high. In addition, the material cost and production cost of the ceramic substrate are relatively high, and the lead time is also longer. Traditional PCB boards can be pressed in multiple layers, and the processing technology is mature.3. Different applications.Ceramic substrates are used in industries that require high heat dissipation, such as high-power LED lighting, high-power modules, high-frequency communications, track power supplies, etc. Traditional PCB boards are more widely used, and the demand is relatively large.Product ParametersAlumina Ceramic SubstrateItemUnit96% Al2O3Mechanical PropertiesColor//WhiteDensityDrainage Methodg/cm3≥3.70Light Reflectivity400nm/1mm%94Flexural StrengthThree Point BendingMPa>350Fracture ToughnessIndentation MethodMPa·m1/23.0Vickers HardnessLoad 4.9NGPa14Young's ModulusStretching MethodGPa340Water Absorption %0Camber/Length‰T≤0.3: ≤5‰, Others: ≤3‰Thermal PropertiesMax.
