basic information
The surface state has fewer pores due to fine particles, and it excels in smoothness and flatness. It also has excellent adhesion to thick and thin film materials. There is little variation in dimensions such as shape and thickness. Warping, bending, and waviness are minimal. Physical and chemical properties remain stable even in high-temperature environments, and it has excellent thermal shock resistance. It has a thermal expansion coefficient close to that of silicon and high thermal conductivity. It has excellent mechanical strength. We also offer high-strength substrates that further enhance strength. It excels in oil and chemical resistance. It has excellent insulation properties, with high dielectric breakdown voltage, surface resistance, and volume resistance, and a low dielectric constant. We also have high-reflectivity substrates suitable for LED applications. ○ For characteristic values and general dimensional tolerances, please visit our website.
