We have added "high-purity alumina (99.6%) substrates" to our lineup and prepared standard samples (100x100x0.2).
■Alumina Ceramic Substrates Born from Our Unique Production System■ In recent years, the electronics industry, which is accelerating the pace of evolution, has developed tiny chip components that can now fit on the tip of a finger, advancing the information society. Among these, chip resistors are essential basic electronic components for constructing electronic circuits. Our alumina ceramics use high-purity alumina raw materials that excel in electrical and thermal properties, achieving excellent dimensional accuracy and divisibility through advanced processing technology. 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.

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, "fine and micro processing" becomes possible. These sheet processing methods can accommodate processing specifications such as "non-standard 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, achieving molding of "3D pillar chips" with dimensions below 0.5mm.
-
By forming a split groove for division through mold forming, 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 precision 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 1mm thick green sheets that were formed and coated, followed by a firing process.
