Thick film printed circuits for electronic component applications Capable of fine circuit printing Unique uniform film formation technology in through-holes Our alumina double-sided circuit boards enable the formation of connections between front and back patterns through our unique through-hole manufacturing technology. Previously, embedding conductors in through-holes was considered difficult due to the shrinkage of conductors during firing. However, we have independently developed a paste that controls firing shrinkage and an optimal process, allowing us to supply alumina printed circuit boards with a via structure filled with conductive paste in the through-holes.

Printed Circuit Boards for Small Electronic Devices Fine circuit printing is a circuit printing technology primarily for ultra-small electronic components. In recent years, as the miniaturization, lightweighting, and high performance of electronic devices have progressed, the demands for high implementation and high density in circuit board packaging have been increasing year by year. To meet these demands, we are leveraging our thick-film printed circuit board (through-hole) technology to develop even more delicate pattern printing techniques.

Application of Our Ceramic Technology to "LED Packages" Our LED ceramic packages utilize unique technologies in sheet molding and printed circuit techniques to provide highly differentiated ceramic packages. By leveraging sheet molding technology, we eliminate the need for molds required for laminated integral molding using high-temperature co-fired ceramics (HTCC), significantly increasing design flexibility. Additionally, by incorporating a segmented structure through mold forming, we facilitate the processing steps in the post-packaging phase. Furthermore, by applying high-reflective materials using printing technology, we achieve functionality as a high-efficiency reflector. Additionally, by employing a consistent in-house process from sheet molding to sintering and circuit printing, we can broadly meet our customers' needs. Please feel free to consult with us.

Ceramic substrates with high reflectivity characteristics We can provide high reflectivity ceramic substrates made from alumina ceramics as the base material. Since no special additives or coatings are used in the manufacturing process, there is no concern about contamination in subsequent processes. Additionally, existing equipment for conventional alumina substrates can be shared, allowing for mass production equivalent to existing products.

Porous ceramic substrate Porous ceramics are ceramics that have countless pores (porous) inside. The presence of pores reduces thermal conductivity and makes the material lightweight. Due to its extremely high permeability, it can be used as a setter in the firing process, resulting in excellent firing quality. Our porous ceramic substrates have a proven track record in processes such as "binder removal promotion" and "firing efficiency improvement through multi-layer stacking" in the firing processes of ceramic products like ferrite substrates and metal injection molding (MIM) products.

Our company utilizes over 50 years of experience in manufacturing ceramic products to produce and sell ceramic plaques and monuments used as art crafts. We burn images and illustrations onto ceramic plaques using a special method. Since there is no concern about fading, we create art crafts made from ceramic materials that are suitable for outdoor installation. We offer ceramic photo plaques (various commemorative photos, pet photos), commemorative ceramic plaques, ceramic signage, ceramic tiles, and more, suitable for gifts and souvenirs. Please feel free to consult with us.
