Product Description
Alumina (Al2O3) Ceramic Substrates
Alumina is the most commonly used technical ceramic material. Thanks to its very good electrical insulation, dielectric strength, and high-temperature resistance up to 1500 °C, Alumina Ceramic is ideal for electrical applications and high-temperature applications.
Alumina ceramics feature:
- Good mechanical strength
- Good heat conductivity and fire resistance
- Good corrosion and wear resistance
- Very good electric insulation
The alumina substrates also possess several unique features:
- Good surface with high smoothness/flatness and less porosity
- High resistance to heat shock
- Low warpage and camber
- Stable in very high temperature and corrosive chemical
- Very stable breaking strength and shape/dimension variance
Applications:
Network resistor, Chip resistor, Chip resistor array, Thick-film hybrid IC, Thin-film hybrid IC, General isolator
