The description of BeO Ceramic Substrate
Beryllium oxide ceramics offer a high melting point and thermal shock resistance. Its thermal conductivity is similar to copper and silver, and it has excellent electrical insulation properties. The thermal conductivity is about 10 times that of alumina at room temperature. 
Heat is the fatal point of the service life and quality of the device. Due to the ideal thermal conductivity of beryllium oxide ceramics, it greatly improves the service life and quality of the device,  is beneficial to the development of the device to miniaturization, and is beneficial to increase the power of the device. Therefore, it can be widely used in aerospace, nuclear power, metallurgical engineering, electronics industry, rocket manufacturing, etc.
Our factory owns a selection of shaping processes for making BeO ceramic substrates, mainly including tape casting, dry pressed and ISO pressed, also we are able to machine these beryllium oxide ceramic components at the house. You can easily find the ideal solutions here that you are looking for.
