This document defines the configuration verification and optional processing requirements for the 114 mm x 114 mm x 1 mm 96% alumina ceramic substrate. Confirm dimensional, surface, and post-processing needs before quotation and final use.
- Configuration verification: Verify the required size tolerance, thickness, material grade, surface finish, and package format for this 96% alumina ceramic substrate.
- Optional post-processing confirmation: Confirm whether polishing, coating, metallization, or custom-shape processing is required for the intended application.
- Quotation specification: Include the exact size, thickness, color or package detail, and quantity when requesting quotation support.
What electrical breakdown voltage and thermal conductivity does the 1 mm thick 96% alumina substrate provide?
The specification lists a breakdown voltage of 15 kV/mm or greater and thermal conductivity above 24 W/(m·K), together with low dielectric constant and low dielectric loss. Across the 1 mm nominal thickness, this corresponds to a breakdown voltage on the order of 15 kV or higher, supporting use in insulating and heat-spreading applications.
Does the 114 mm x 114 mm x 1 mm alumina substrate require polishing, coating, or metallization confirmation before circuit fabrication?
The product is supplied as a bare 96% alumina ceramic substrate, and the page instructs buyers to confirm polishing, coating, metallization, or custom-shape needs with the technical sales team when required for the application. The as-specified surface finish is Ra 0.15–0.30 µm, so verify that finish against your deposition or patterning process before ordering.
How mechanically robust and chemically stable is this 96% alumina substrate for handling and process environments?
The datasheet specifies flexural strength greater than 350 MPa, Vickers hardness of 14 GPa, and density of at least 3.70 g/cm³, providing high mechanical strength, hardness, and a high melting point. It is also characterized by good corrosion resistance and chemical stability, supporting demanding laboratory and process conditions.
This 96% alumina ceramic substrate with a 1 mm thickness and 114 x 114 mm footprint provides high flexural strength (>350 MPa) and a Vickers hardness of 14 GPa, making it suitable for structural and insulating layers in high-temperature laboratory jigs or thin-film deposition stages. Its specified Ra surface roughness of 0.15-0.30 μm requires careful handling to maintain surface integrity during substrate cleaning and mounting.
Positive
- High dielectric breakdown strength: Breakdown voltage =15 kV/mm and low dielectric constant and loss provide reliable electrical insulation in RF and high-voltage lab setups.
- Chemical and thermal stability: Corrosion resistance, chemical stability, and thermal conductivity >24 W/(m·K) enable use in aggressive chemical or thermal cycling environments common in ceramics processing.
Trade-offs
- Surface roughness constraint: Ra 0.15-0.30 μm surface finish is not mirror-polished; applications requiring ultra-smooth substrates for thin-film adhesion or optical flatness may require additional polishing.
- Fixed size and brittleness: The 114 x 114 mm x 1 mm format is not re-sizable without risk of edge chipping or fracture, and the brittle nature of 96% alumina demands careful clamping and handling during integration.
