Beryllium Oxide Substrate Description
Beryllium Oxide Substrate, also known as BeO ceramic substrate, is engineered for demanding electronic applications requiring superior heat management and strong dielectric properties. Using active metallization processes like molybdenum-manganese (Mo-Mn) or tungsten-manganese (W-Mn), a robust thick-film metal layer is applied to the surface. After nickel plating and fine-pattern etching, the resulting circuit layer achieves excellent solderability and structural integrity, with tensile strength exceeding 20 MPa. Even under reducing atmospheres at around 800 °C, the nickel layer remains stable without blistering. This makes BeO substrates a dependable platform in high-frequency, high-power electronics, especially in aerospace and telecommunication systems.

Beryllium Oxide Ceramic Properties
Beryllium Oxide Ceramic Material Machining
Beryllium Oxide (BeO) Ceramic is valued for its exceptional thermal conductivity, electrical insulation, and high melting point. These qualities make it widely used in electronics and high-temperature applications, but its hardness and brittleness require special machining approaches. Key machining considerations include:
- Cutting: Precision diamond-coated tools or laser cutting are essential to avoid microcracks and maintain clean edges, as BeO’s brittleness can lead to chipping during conventional cutting.
- Grinding: Fine diamond grinding wheels enable accurate shaping and surface finishing while minimizing the risk of fractures, especially important for small or complex parts.
- Drilling: Ultrasonic machining or abrasive waterjet methods are preferred to produce precise holes without causing thermal damage or cracks.
- Surface Finishing: Polishing techniques enhance surface smoothness and electrical insulation properties, crucial for applications demanding high dielectric performance and reliability.
Beryllium Oxide Ceramic Packaging
Beryllium Oxide Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of the products in their original condition.
