Product Description High Purity Aluminum Oxide Plate Fine Ground 96 Al2O3 Alumina Ceramic SubstrateProduct IntroductionWe are a supplier of customized alumina ceramic substrates. Our products are environmentally friendly, highly stable, corrosion-resistant, high-temperature resistant and with accurate dimensions. If you need alumina ceramic substrates, please choose Jinghui for fast production and delivery!Alumina ceramic is the most common substrate material you'll find in today's printed circuit boards. It boasts an excellent balance of thermal and electrical conductivity when compared to other oxide ceramic substrates.The alumina ceramic substrate is also reputed for better mechanical strength and chemical stability and is readily available. These properties make it the ideal option for technical manufacturing, especially when various shapes have to be considered. If used in circuit boards, the purity of alumina is usually 96% or 99.6%. Product SpecificationsBelow we will focus on the 96% alumina ceramic substrates. If you are interested in 99.6% alumina, please contact us to learn more.We can produce a variety of specifications and the table below shows our standard sizes. 96% Alumina Ceramic SubstrateThickness (mm)Maximum Size (mm)ShapeForming MethodAs FiredLappedPolishedRectangularSquareRound0.25120114.3114.3 √ Tape Casting0.3120114.3114.3 √ Tape Casting0.38140×190 √ Tape Casting0.5140×190 √ Tape Casting0.635140×190 √ Tape Casting0.76130×140 √ Tape Casting0.8130×140 √ Tape Casting0.89130×140 √ Tape Casting1280×240 √ Tape Casting1.5165×210 √ Tape Casting2500×500 √ Tape CastingOther special thicknesses within the thickness range of 0.1-2.0mm can be achieved by lapping.Manufacturing Capacity1.
