AI Overview
(alumina) substrates are high-purity ceramic materials, often termed thin-film substrates, designed for high-performance electronics. They offer superior surface smoothness, high mechanical strength, excellent electrical insulation, and high-frequency capabilities.
Key Characteristics and Applications
- Performance: Higher purity (99.6%) enables smaller grain sizes, resulting in smoother surfaces (often <1 -in roughness) and superior electrical properties compared to 96% alumina.
- Applications: Ideal for thin-film circuits, RF modules, sputtering, high-density packaging, and as heat sink substrates in high-power electronics.
- Thermal Properties: Provides higher thermal conductivity (approx. 28-30 W/m·K) than lower-purity alumina.
- Processing: Compatible with advanced metallization techniques like sputtering, evaporation, and chemical vapor deposition.
