| Tape Substrates for Thick Film |
 |
We are producing 96% alumina substrates (A-476)
and 93% alumina substrates (A-473T) which have excellent thick film reliability
and consistency.
 Features
Our substrates have excellent thick film reliability and precise dimensional tolerance
control (Super premium: ±0.25%). They are cost effective for through-hole
processes with small diameter holes (Min. 0.2mm) allowing densification of precision
circuitry.

| Glazed Substrates for Thermal Printheads |
|
Features
Kyocera glazed substrates consist of 96% alumina with a glass overcoat. They have
superior flatness and fewer surface defects so it is very applicable for thermal
printheads used in advanced and downsized facsimile machines. Kyocera can provide
various types of glazed substrates for each application such as partial glazed,
full glazed and serial glazed substrates.

| Microwave Dielectric Ceramics |
|
1.Filter, Isolator, MIC
Features
|
Miniaturization of circuit size is possible due to the ceramic's high dielectric
constant. |
|
High Q values even at high frequencies. |
|
Stable circuit operation can be obtained due to the low temperature coefficient
of the dielectric constant. |
|
Because of a wide range of dielectric values, circuit design can be tailored
to fit the application more easily. |
|
Surface finish can be selected to allow use with thin film or thick film technologies. |
|
Numerous custom designs such as holes, complicated 3 dimensional shapes, and
snaplines are available due to Kyocera's advanced dry press technology. |

| Sapphire
Substrate |
|
The demand for single crystal sapphire has been
expanding rapidly due to its superior electrical and mechanical properties, chemical
stability and light transmission. Kyocera mass produces single crystal sapphire
using the " EFG " growing method which provides the advantages of crystal
orientation control, and the flexibility of configuration in cross section.
