This substrate exhibits high flexural strength and fracture toughness but is susceptible to thermal shock if subjected to rapid temperature changes outside its rated range. Mechanical integrity may be compromised by improper clamping or point loading during processing.
- Thermal operating range: Maintain use temperature between -55 °C and 850 °C to avoid thermal stress-induced cracking.
- Mechanical handling precaution: Avoid concentrated point loads or uneven clamping forces that may exceed the substrate's flexural strength limit of 600 MPa.
- Electrical breakdown constraint: Do not apply voltages exceeding 15 kV/mm across the substrate thickness to prevent dielectric failure.
This substrate requires careful handling to preserve its mechanical and electrical properties before use. Proper cleaning and inspection steps ensure optimal performance in demanding applications.
Required Equipment: Cleanroom-grade gloves, Isopropyl alcohol, Lint-free wipes
- Inspect substrate
Visually examine the substrate for chips, cracks, or surface defects before any processing step. - Clean surface
Wipe the substrate with isopropyl alcohol using a lint-free wipe to remove particulate contamination. - Dry thoroughly
Allow the cleaned substrate to air dry in a particle-free environment for at least 5 minutes. - Mount for processing
Secure the substrate using a uniform clamping fixture to distribute mechanical load evenly across the surface.
What are the key mechanical and thermal properties of the Atomfair AF-SIN-S114P070 silicon nitride ceramic substrate?
The substrate has a flexural strength >600 MPa, fracture toughness 6.5 MPa√m, Young's modulus >310 GPa, Vickers hardness >15 GPa, thermal conductivity >60 W/(m·K), and apparent density ≥3.22 g/cm³. These properties make it suitable for high-stress, high-temperature applications.
Can the 114 mm x 114 mm x 0.7 mm silicon nitride substrate be supplied with metallization or custom coatings?
Yes, Atomfair offers optional polishing, coating, metallization, and custom-shape fabrication for this substrate. Buyers should confirm these requirements with the technical sales team to ensure compatibility with their application.
What is the maximum operating temperature and electrical breakdown voltage of this silicon nitride substrate?
The usable temperature range is -55°C to 850°C, and the breakdown voltage exceeds 15 kV/mm. These specifications allow use in high-temperature and high-voltage environments, but proper handling is required to avoid mechanical damage despite its high fracture toughness.
This 114 mm x 114 mm x 0.7 mm silicon nitride ceramic substrate offers high flexural strength (>600 MPa) and fracture toughness (6.5 MPa·√m), providing robust mechanical stability for demanding ceramic substrate applications in laboratory or research settings.
Positive
- High mechanical strength and toughness: With flexural strength exceeding 600 MPa and fracture toughness of 6.5 MPa·√m, this substrate resists cracking and deformation under mechanical stress, suitable for high-load applications.
- Broad operational temperature range: Usable from -55 °C to 850 °C, this substrate maintains structural and electrical integrity across extreme thermal cycles, enabling deployment in diverse thermal environments.
Trade-offs
- Requires specification verification: Size tolerance, thickness requirement, material grade, and surface finish must be confirmed before procurement to ensure compatibility with the intended application.
- Processing needs custom confirmation: Options such as polishing, coating, or metallization require explicit specification, adding lead time and potential additional cost for customized modifications.
