What is the surface roughness and flexural strength of the 96% alumina ceramic substrate 150 mm x 150 mm x 0.635 mm?
The substrate has a surface roughness of Ra 0.15–0.30 µm and a flexural strength greater than 350 MPa. These specifications, combined with a Vickers hardness of 14 GPa and a density of ≥3.70 g/cm³, indicate suitability for applications requiring high mechanical integrity and a smooth surface for thin-film deposition or metallization.
Can this 96% alumina substrate be used for high-voltage isolation in power electronics?
Yes, the substrate provides a breakdown voltage of ≥15 kV/mm, making it suitable for high-voltage isolation in power modules and thick-film hybrid circuits. Its low dielectric constant and low dielectric loss, combined with a thermal conductivity >24 W/(m·K), support efficient heat dissipation while maintaining electrical insulation.
What handling or storage precautions are recommended for the 96% alumina ceramic substrate?
The substrate is a dense, white ceramic with high hardness (14 GPa) but is brittle; handle with care to avoid chipping or cracking. Store in a clean, dry environment to prevent surface contamination, as the Ra 0.15–0.30 µm finish is critical for subsequent processing steps such as metallization or thin-film deposition.
This 96% alumina ceramic substrate (150 mm x 150 mm x 0.635 mm, pack of 10) delivers high mechanical strength (>350 MPa flexural), electrical insulation (≥15 kV/mm breakdown), low dielectric loss, and thermal conductivity >24 W/(m·K), making it suitable for high-temperature, corrosive, or electrically demanding lab applications. The 0.15-0.30 μm surface roughness and dense white microstructure support consistent thin-film deposition or bonding, though machining post-purchase requires specialized diamond tooling.
Positive
- High mechanical and dielectric strength: Flexural strength >350 MPa and breakdown voltage ≥15 kV/mm ensure structural integrity under mechanical load and high-voltage isolation, critical for power electronics or vacuum chamber feedthroughs.
- Thermal and chemical resilience: Thermal conductivity >24 W/(m·K) combined with good corrosion resistance and chemical stability allows use in high-temperature or aggressive solvent environments without degradation.
Trade-offs
- Brittle under point loading: As a ceramic, the substrate is brittle; although flexural strength exceeds 350 MPa, localized impact or uneven clamping can cause fracture without ductile deformation, requiring careful handling.
- Machining requires diamond tooling: The 14 GPa Vickers hardness makes post-fabrication cutting, drilling, or shaping impractical without diamond-coated tools and coolant, limiting on-site customization.
