A must-see for automobile manufacturers! Alumina ceramics, high-performance ceramics.
A specialized manufacturer of high-performance ceramic substrates produces alumina ceramic substrates that are widely recognized, using its unique production system.
■Alumina Ceramic Substrates Born from Our Unique Production System■ In recent years, the electronics industry, which is accelerating the pace of evolution, has developed chip components that are now small enough to fit on a fingertip, advancing the information society. Among these, chip resistors are essential basic electronic components that make up electronic circuits. Our alumina ceramics use high-purity alumina raw materials with excellent electrical and thermal properties, and through advanced processing technology, we achieve outstanding dimensional accuracy and divisibility. For other alumina ceramic products as well, we use high-purity alumina raw materials tailored to their applications, maintaining stable quality and excellent characteristics while producing under a strict quality control system.

Detailed information
-
The widely recognized "alumina ceramics" generally corresponds to our product line "KA6 Series" (KA6, KA62, KA6-470. Alumina purity = 96%~97%). You can choose from the lineup according to your application. Various sizes are available.
-
Through an in-house integrated process, we achieve molding processing of green sheets that meets customer specifications by using mold press processing. In particular, by utilizing precision mold press processing technology, we enable "fine and micro processing." These sheet processing methods can accommodate processing specifications such as "irregular shapes," "through holes," and "split slits" on sintered ceramic substrates by applying press processing using high-precision molds. In the case of chip resistors, we have a production record for the minimum chip size of 0603 (0.6mm x 0.3mm). For split slits, we have achieved mass production with a minimum depth of 0.08mm. By applying advanced slit management, we can provide "split chip sizes of 50% of the board thickness." We also support three-dimensional mold press processing, not limited to flat substrate shapes, and have a track record of molding "three-dimensional pillar chips" of less than 0.5mm.
-
By forming a slit groove for division through mold shaping, it becomes possible to process individual pieces. The minimum size can be as small as 0.6mm × 0.3mm.
-
By using laser processing, it becomes possible to achieve high dimensional accuracy in shape processing. Fine hole processing (minimum Φ0.05mm) is possible.
-
Laminated processing allows for the thickening of ceramic substrates. The photo above shows a 2mm thick ceramic substrate created by stacking two green sheets that were coated and formed to a thickness of 1mm each, followed by firing.
