Alumina substrate is a new type of precision ceramic made of aluminum oxide. It has a wide range of uses, such as hybrid integrated circuit interconnect substrates, optoelectronic device substrates, chip capacitors, sensors and other electronic industries. Alumina substrates that have undergone a polishing process can be suitable for multi-layer thin film technology.
GORGEOUS is a manufacturer specializing in the manufacture of precision ceramics, producing high-quality advanced ceramics. We provide a variety of substrate ceramics such as alumina substrates, aluminum nitride substrates, and beryllium oxide substrates.
Neat and smooth: Our products have neat smoothness and low porosity (warpage ≤ 0.003/mm). Higher surface flatness can increase the contact area between the chip and the alumina substrate, providing reliable support and heat transfer for precision circuit components.
Fine workmanship: We have fine workmanship and control the product tolerance to the minimum. The same model of ceramic substrates has almost no difference in outline and thickness.
Powerful heat dissipation: Our alumina substrate has good heat dissipation capacity, which can reduce the heating of circuit components to a certain extent.
Excellent insulation: Alumina substrate has good electrical insulation, high surface resistivity and volume resistivity, and small dielectric constant, which is very suitable for the electrical industry.
Thermal conductivity: Alumina substrate is often used in applications that require good thermal management. Our products have excellent thermal conductivity, which can reach 30-35W/(m·k). They can conduct heat well and help electronic devices maintain stable performance.
We provide customized alumina substrate services. The size, thickness, and purity (96-99.9) can all be customized according to your needs. The following are some common alumina substrate sizes for your reference (customized products do not have specific sizes)
