Ontwerpoverwegingen voor SiC-producten

Designing for manufacturability is paramount when working with SiC, given its inherent hardness and brittleness. Careful consideration during the design phase can significantly impact the final product’s quality and cost:

• Geometrie Limieten: Avoid sharp corners, thin walls, and abrupt changes in cross-section, as these can create stress concentrations and make machining difficult.
• Wanddikte: Aim for uniform wall thicknesses to minimize warping during sintering and to improve thermal shock resistance.
• Spanningspunten: Identify potential stress points and reinforce them, or consider design modifications to distribute stress evenly.
• Onderdeelgrootte en complexiteit: While SiC can be formed into complex shapes, larger and more intricate designs may require specialized manufacturing techniques and can impact lead times.
• Toleranties: Communicate required tolerances clearly, understanding that tighter tolerances typically increase machining costs.
• Bevestigingsmethoden: Plan for appropriate attachment methods (e.g., brazing, mechanical fastening) that account for SiC’s properties.

Tolerantie, Oppervlakteafwerking & Maatnauwkeurigheid

Achieving precise tolerances and specified surface finishes is critical for the performance of custom SiC components. While SiC is a hard material, advanced machining techniques enable high levels of accuracy:

• Haalbare toleranties: Precision grinding and lapping can achieve tolerances in the micron range (e.g., ±5 μm to ±25 μm), depending on the part’s size and complexity.
• Opties voor oppervlakteafwerking: Surface finishes can range from rough ground to highly polished, with roughness values (Ra) ranging from several micrometers down to nanometers for critical sealing or optical applications.
• Maatnauwkeurigheid: With controlled processing, high dimensional accuracy can be maintained throughout the manufacturing process, crucial for components in sensitive equipment like semiconductor wafer handling systems.

Close collaboration with your SiC supplier is essential to define these specifications accurately and ensure they are achievable within your project’s budget and timeline.

Behoeften aan nabewerking

Even after initial forming and sintering, many SiC components undergo post-processing steps to achieve their final desired properties and performance:

• Slijpen: Precision grinding is often used to achieve tight dimensional tolerances and desired surface finishes. Diamond grinding wheels are typically employed due to SiC’s extreme hardness.
• Leppen en polijsten: For ultra-flat surfaces or mirror finishes required in optics or sealing applications, lapping and polishing with fine abrasive slurries are performed.
• Afdichting: In certain applications, especially where porosity might be an issue (e.g., some RBSiC grades), sealing processes can be applied to create an impervious surface.
• Coating: Specialized coatings, such as chemical vapor deposition (CVD) SiC, can be applied to enhance surface purity, improve corrosion resistance, or modify electrical properties.
• Hole Drilling: Precision holes can be drilled using laser drilling or ultrasonic machining.
• Inspectie en testen: Comprehensive inspection, including CMM measurements, dye penetrant inspection, and ultrasonic testing, ensures product quality and integrity.

Veelvoorkomende uitdagingen en hoe deze te overwinnen
