Product Description
High Purity Alumina Ceramic Substrate Overview
High purity alumina ceramic substrates with 99.7% Al2O3 content are engineered for superior performance in demanding electronic applications. These advanced ceramic materials offer exceptional thermal management, electrical insulation, and mechanical stability.
Material Properties & Classification
Alumina ceramics are categorized into high-purity (99.9%+ Al2O3) and standard types. High-purity variants sinter at 1650-1990°C and transmit wavelengths of 1-6μm, making them ideal replacements for platinum crucibles in glass melting applications.
Primary Applications
- LED package substrates
- Chip resistor bases
- Hybrid integrated circuit (HIC) substrates for heat dissipation
- Power module components
- Thermal printer head substrates for FAX systems
Key Performance Characteristics
Our alumina substrates deliver optimal balance between insulation properties, thermal conductivity, and mechanical strength. The exceptional surface roughness control ensures superior quality for precision applications.
- Excellent surface smoothness and flatness with minimal porosity
- Superior adhesion compatibility with thin film and thick film materials
- Minimal dimensional variance in outline, plate thickness, and slit pitch
- Outstanding thermal shock resistance with high thermal conductivity
- Thermal expansion coefficient closely matched to silicon
