Thin Ceramic Sheet
■Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
■Less variance in outline, plate thickness, slit pitch, etc.
■Minimal warpage, bending, and undulation.
■Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.
■Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
■Excellent resistance against oil and chemical.
■Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
■Stable breaking strength, and less variance in shape or dimensions.
■The high reflective substrate, especially suitable for optical applications such as LED, is also available.
Applications of Thin Ceramic Sheet / Ceramic Disc :
LED packages, Thin Ceramic Sheet / Ceramic Disc for chip resistors, HIC substrates for heat dissipation, Power modules, FAX substrates for thermal printer head
