SiC Heat Ceramic Plate Applications

Silicon Carbide Ceramic Plate in Power Electronics Cooling

In EV inverter modules, IGBT power units, and laser diode systems, thermal management is critical. SiC ceramic plates are used as heat spreaders or substrates to dissipate heat efficiently while maintaining electrical insulation. Their high thermal conductivity and mechanical strength ensure stable operation under continuous thermal cycling.

Example: In a 1200V IGBT module, a 2mm thick SiC plate with 120 W/m·K thermal conductivity reduces junction temperature by 15°C compared to Al₂O₃ substrates, improving system reliability.

SiC Ceramic Plate Usage Instructions

• Installation: Ensure flat contact with the heat source and the heat sink. Use thermal interface material (TIM) if needed.
• Cleaning: Use isopropyl alcohol or deionized water. Avoid acidic or alkaline cleaners.
• Storage: Store in a dry, dust-free environment. Avoid stacking without padding.
• Handling: Avoid dropping or bending. Use gloves to prevent contamination.
• Maintenance: Inspect for cracks or surface damage before reuse.

Common Misuse:

• Over-tightening mounting screws may cause cracking.
• Using incompatible TIMs may reduce thermal performance.
