How does the 96% alumina ceramic substrate balance mechanical, thermal, and electrical performance for demanding insulation applications?
This 96% Al2O3 substrate provides a dense white ceramic body with flexural strength >350 MPa, Vickers hardness of 14 GPa, breakdown voltage of 15 kV/mm, and thermal conductivity >24 W/(m·K), while also offering low dielectric constant and dielectric loss. These properties make it suitable for applications requiring electrical insulation, mechanical rigidity, and moderate heat spreading; however, frequency-dependent dielectric data is not stated in the listing, so it should be verified for high-frequency circuit designs.
What dimensional and surface specifications must be verified before integrating this 30 mm x 30 mm x 0.63 mm 96% alumina substrate into a device build?
The selected specification is 30 mm x 30 mm x 0.63 mm, supplied in a pack of 50, with a 96% Al2O3 grade, white dense appearance, and surface roughness Ra 0.15-0.30 μm. The catalog directs buyers to confirm size tolerance, thickness requirement, material grade, surface finish, and package format, so these parameters should be verified before integration.
Does the 96% alumina substrate come ready for immediate use, or must polishing, coating, metallization, or custom shaping be specified separately?
The source does not indicate that polishing, coating, metallization, or custom shaping are included, so the substrate should be treated as a bare 96% alumina ceramic plate unless confirmed otherwise. Buyers are instructed to confirm these options when required for the application and to include exact size, thickness, color or package detail, and quantity when requesting quotation support.
This 96% alumina ceramic substrate provides a balanced combination of high flexural strength (>350 MPa), electrical insulation (breakdown voltage ≥15 kV/mm), and moderate thermal conductivity (>24 W/(m·K)), making it suitable for demanding electronic and structural applications where thermal management and dielectric performance are critical. Its low surface roughness (Ra 0.15–0.30 μm) supports precise thin-film deposition, but the specified dimensions (30 mm x 30 mm x 0.63 mm) and as-fired finish may limit direct use in systems requiring specific metallization patterns or tighter tolerances.
Positive
- High mechanical and electrical resilience: Flexural strength >350 MPa and Vickers hardness of 14 GPa provide robust structural integrity, while breakdown voltage ≥15 kV/mm ensures reliable electrical insulation in high-voltage lab setups.
- Low dielectric loss with useful thermal conduction: The 96% Al₂O₃ formulation yields a low dielectric constant and dielectric loss, combined with thermal conductivity >24 W/(m·K), enabling efficient heat dissipation in RF or power electronic substrates.
Trade-offs
- Surface finish and dimensional constraints: As-fired surface roughness (Ra 0.15–0.30 μm) may necessitate additional polishing for certain thin-film or photolithography processes, and the 0.63 mm thickness limits mechanical flexibility in non-flat mounting configurations.
- Post-processing required for specialized applications: Custom metallization, coating, or shaping is not pre-applied, requiring separate procurement steps and compatibility verification for advanced circuit or bonding applications.
