Characteristics and Applications of Various Ceramic Substrates

Consistent production from manufacturing ceramics substrates with low dielectric loss in the microwave band, microwave dielectric substrates, to the formation of thin film patterns.

【High-Quality Alumina Substrate】 ○ Dense ○ The three-point bending strength is 660 MPa, which is significantly higher, about twice that of conventional products ○ Excellent electrical properties with low dielectric loss in the high-frequency range 【Zirconia Substrate】 ○ High strength and high toughness ○ Large elastic deformation capacity in bendable ceramics 【High Dielectric Substrate】 ○ Due to its high relative permittivity, it enables miniaturization of high-frequency circuits compared to alumina substrates ○ Low dielectric loss even in the high-frequency range 【Thin Film Integrated Circuit】 (Circuit formation on various ceramic substrates) ○ Formation of air bridges, side patterns (0.5t or more), and AuSn solder patterns is possible ○ Simultaneous mounting of conductors, thin-film resistors, and thin-film inductors is possible ○ By combining a unique 99.9% alumina substrate with fine patterns, it enables the formation of low-loss and low-noise circuits in the high-frequency range ○ Substrate materials also include high dielectric substrates, aluminum nitride substrates (AlN substrates), and quartz substrates.

High-strength alumina substrate for thin films

Ideal for thin film circuit formation! JFC's unique alumina substrate with high strength, high purity, and excellent planar smoothness.

The high-strength alumina substrates for thin films manufactured by our company feature a dense and smooth surface achieved through the use of fine and uniform raw powder, making them suitable for the formation of fine thin film circuits. Due to their high purity and bending strength, they are resistant to cracking even when the substrates are made thin, and they excel in handling, contributing to the miniaturization and thinning of the substrates. They are increasingly being adopted for temperature sensors and chip resistors.
