Company Profile
Product Details
alumina substrate,ceramic substrate,alumina ceramic substrate,ceramic pcb substrate
This alumina substrate with excellent characteristics was made possible thanks to our own
thin sheet ceramics manufacturing technology.
We also handle processed alumina substrates with fine rounded/square holes or slits, as well as polished
substrates.
Main Applications
- A. High-frequency thin film circuit substrates
- B. Capacitor/resistor substrates
- C. Sensor component substrates
Features
- A.Low surface roughness
Even heat treated products have a surface roughness that is equivalent to that of polished products.
(Ra 0.03μm) - B.High bending strength
It has a three-point bending strength of 660 MPa which is approximately twice that of conventional substrates. - C.High purity
It is made from 99.9% pure alumina. - D.Fine material properties
It is a dense material with few internal pores. - E.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.
