Alumina Substrates (Substrates for Milli/Micro-Wave Devices)
This alumina substrate with excellent characteristics was made possible thanks to our own thin sheet ceramics manufacturing technology.
We also handle processed substrates with fine rounded/square holes or slits, as well as polished substrates.
Main Applications
- High-frequency thin film circuit substrates
- Capacitor/resistor substrates
- Sensor component substrates
Features
- Low surface roughness
Even heat treated products have a surface roughness that is equivalent to that of polished products.
(Ra 0.03μm) - High bending strength
It has a three-point bending strength of 660 MPa which is approximately twice that of conventional substrates. - High purity
It is made from 99.9% pure alumina. - Fine material properties
It is a dense material with few internal pores. - Good electrical characteristics
Low dielectric loss tangent in the high frequency band.
(tanσ:10-4 at10 GHz) - Ultra-thin substrates with a thickness of 0.1 mm are also available.
Note: In addition to our high-grade alumina substrates we also provide ones with a purity of 99.5%.
