What mechanical and electrical performance can be expected from the 96% alumina ceramic substrate at 28 mm x 28 mm x 1 mm?
This dense white 96% Al2O3 substrate provides flexural strength greater than 350 MPa, Vickers hardness of 14 GPa, and breakdown voltage of at least 15 kV/mm. It also offers low dielectric constant and dielectric loss, useful thermal conductivity above 24 W/(m·K), and a density of 3.70 g/cm³. These properties support high mechanical strength and reliable electrical insulation in technical ceramic applications.
Can this 96% alumina substrate be supplied with polishing, coating, metallization, or custom shapes for device fabrication?
This item is listed as an independent 28 mm x 28 mm x 1 mm substrate, so polishing, coating, metallization, or custom-shape needs must be confirmed separately when they are required for the application. Atomfair's technical sales team can support option matching, model selection, accessory matching, and configuration confirmation before quotation. Include the exact size, thickness, surface finish, and quantity when requesting quotation support.
What specification details should be verified before ordering this alumina ceramic substrate to avoid procurement errors?
Before quotation, confirm the exact Atomfair model AF-A96-S028P100, size, thickness, material grade, surface finish, and package format. The selected specification is 28 mm x 28 mm x 1 mm in a pack of 50, with a surface roughness of Ra 0.15–0.30 µm. Include these details and the required quantity when requesting quotation support.
This 96% alumina ceramic substrate (28 mm x 28 mm x 1 mm, pack of 50) provides a dense, high-strength Al2O3 ceramic with >350 MPa flexural strength and ≥15 kV/mm breakdown voltage, suitable for demanding electrical insulation and thermal management in lab-built test fixtures or prototype assemblies.
Positive
- High mechanical and dielectric strength: Flexural strength >350 MPa and breakdown voltage ≥15 kV/mm provide reliable structural integrity and electrical isolation under high-voltage laboratory conditions.
- Moderate thermal conductivity for alumina: With thermal conductivity >24 W/(m·K), this substrate efficiently dissipates heat from mounted components, reducing thermal stress in power electronics or high-temperature test setups.
Trade-offs
- Surface roughness limits fine-pattern adhesion: A surface roughness of Ra 0.15-0.30 µm may require polishing or additional surface preparation for thin-film metallization or high-resolution photolithographic patterning.
- Brittle fracture risk under mechanical shock: Despite high flexural strength, ceramic substrates are susceptible to brittle fracture if subjected to sharp impacts or non-uniform clamping loads during handling or assembly.
