Alumina ceramic substrate is made of al2o3 ceramic with 96% purity, it is an ideal choice for electronic packaging applications. It has much better performance than traditional epoxy resin substrate and metal substrate like higher thermal conductivity, better mechanical strength, better electrical insulation etc. Because of the low cost, excellent performance and short production time, 96% alumina ceramic substrate is more and more widely applied in electronic industries.
✔ High mechanical strength and hardness
✔ Good electrical insulation
✔ Low dielectric constant and dielectric loss
✔ Similar thermal expansion with Si
✔ High thermal conductivity
✔ Excellent corrosion resistance
✔ Available for surface metallization

Applications of Alumina Ceramic Substrates
Aluminum oxide ceramic substrates are widely used in electronics industry, large scale integrated circuits, hybrid ICs, semiconductor packages, chip resistors, network resistors, focus potentiometers, power modules, power hybrid circuits and other related fields.
Production Process for Ceramic Substrates
Alumina ceramic substrates are made by tap casting, it is a molding method to obtain a uniformly dispersed film of desired thickness from ceramic slurry. The method has advantages of continuous operation, high production efficiency, high automation level, good consistency of molded shapes and dimensions, stable performance of molded parts. It is very suitable for thin plate shapes.
