Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, specifically to a ceramic substrate grease printing mechanism. Background Technology

[0002] Ceramic heat sinks hold a vital position in the field of heat dissipation due to their superior performance. Their main advantages include: 1. Excellent heat dissipation performance: Ceramic heat sinks outperform aluminum heat sinks per unit area, effectively improving heat dissipation efficiency; 2. Low heat capacity: Compared to metal heat sinks, ceramics have a lower heat capacity, preventing the formation of a "thermal ladder" that affects heat dissipation; 3. Insulation performance: Ceramic heat sinks possess excellent insulation properties, effectively reducing electromagnetic interference and making them suitable for high-current, high-voltage environments; 4. High temperature resistance and oxidation resistance: The ceramic material itself is resistant to high temperatures and oxidation, enabling long-term stable operation in harsh environments.

[0003] However, existing ceramic heat sinks have microscopically uneven surfaces, necessitating the application of thermal grease to increase their surface contact area. Therefore, there is an urgent need to develop a ceramic substrate grease application mechanism to meet practical application requirements. Utility Model Content
