This document records the configuration and compatibility constraints reported for the Atomfair silicon nitride ceramic substrate model AF-SIN-S114P050. It is limited to constraints explicitly stated in the product listing and does not restate general material specifications.
- Order configuration: Verify size tolerance, thickness requirement, material grade, surface finish, and package format before ordering this substrate.
- Surface modification options: Confirm polishing, coating, metallization, or custom-shape requirements when these options are required for the application.
- Thermal exposure: Operate the substrate only within its stated usable temperature range to avoid exceeding the material's thermal stability limits.
- Environmental compatibility: Confirm chemical compatibility with the intended service environment before relying on the material's stated corrosion resistance.
What are the key mechanical and thermal properties of this silicon nitride ceramic substrate?
This 114 mm x 114 mm x 0.5 mm silicon nitride substrate offers flexural strength above 600 MPa, fracture toughness of 6.5 MPa√m, and thermal conductivity exceeding 60 W/(m·K). It maintains stable performance across a usable temperature range of -55 °C to 850 °C, with a Young's modulus above 310 GPa and Vickers hardness above 15 GPa.
Can this silicon nitride substrate be supplied with metallization or custom shapes?
Yes, the product description explicitly lists polishing, coating, metallization, and custom-shape fabrication as available options. Buyers should confirm these requirements with the technical sales team to ensure proper configuration for their application.
What is the dielectric breakdown voltage of this silicon nitride substrate?
The specified breakdown voltage is greater than 15 kV/mm, confirming high electrical insulation suitable for demanding high-voltage ceramic substrate applications.
This 114 mm x 114 mm x 0.5 mm silicon nitride ceramic substrate offers a combination of high flexural strength (>600 MPa), fracture toughness (6.5 MPa√m), and thermal conductivity (>60 W/(m·K)), making it mechanically robust for demanding substrate applications, though its thin 0.5 mm profile introduces handling fragility and requires careful deployment to avoid fracture.
Positive
- High mechanical and thermal performance: With flexural strength >600 MPa, fracture toughness 6.5 MPa√m, and thermal conductivity >60 W/(m·K), this substrate resists mechanical stress and dissipates heat effectively in demanding ceramic substrate applications.
- Wide operating temperature range: Usable from -55 °C to 850 °C, the substrate maintains structural stability and insulation properties across extreme thermal environments, suitable for high-temperature or cryogenic lab setups.
Trade-offs
- Thin form factor handling constraints: The 0.5 mm thickness, while enabling compact designs, increases susceptibility to mechanical shock or edge chipping during handling, requiring careful mounting and precision tools to avoid damage.
- Custom processing requirements: Polishing, coating, metallization, or custom shaping must be confirmed prior to procurement, adding lead time and requiring specification verification to match application fit.
