96% Al2O3 (Aluminum Oxide) 2.25" X 2.25"X .060" As Fired
Aluminum Oxide is the standard microelectronic substrate material for the vast majority of applications. Although it has low thermal conductivity - it has excellent mechanical and electrical properties and is used in DC to High Frequency applications. Al2O3 is available in standard 96% grade for low cost, general electronics and 99.6% for higher frequency applications. Aluminum Oxide is the first and only choice for many designers.
Aluminum oxide ceramic substrates possess:
- High mechanical strength
- Low Thermal Conductivity
- Good Dielectric properties
- Excellent high temperature characteristics
- Excellent metalizing properties for thick film, thin film, and DBCu films
- Excellent electrical insulation
- Good corrosion and wear resistance
- Available in as-fired, lapped, and polished grades
