MFeatures of the alumina ceramic substrates
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 the alumina substrates
LED packages, Substrate for chip resistors, HIC substrates for heat dissipation, Power modules, FAX substrates for thermal printer head and other industry
*Various processing is available (thin film metalization, thick film metalization, glaze, etc.)
Features of the silicon nitride ceramic substrate
High Bending Strength about Twice as high as Alumina and Aluminum Nitride (AlN) Substrate
High Thermal Conductivity about Three Times Higher than Alumina and ZTA substrate
Excellent Insulation Properties, High Dielectric Breakdown Voltage, High Surface Resistivity / Volume Resistivity
Coefficient of Thermal Expansion (CTE) Close to Silicon
Applications of the silicon nitride ceramic substrate
Circuit Substrate, Heatsink, Heat Spreader and other industry
Features of the zirconia toughened ceramic substrates
Well controlled surface roughness with homogeneous and fine microstructure
50% higher bending strength than Alumina or AlN substrates.
20% higher thermal conductivity than alumina substrates.
The optical reflectivity is higher than alumina substrates. The substrate with higher reflectivity is also available.
Higher electrical insulation and smaller dielectric constant than alumina substrates.
