Beyond Light Blocking: Anti-Static Advantages of Black Alumina Ceramics in Optoelectronic Packaging

By -

As optical communication, LiDAR, and high-precision optoelectronic detection systems evolve toward higher power and greater integration density, they place higher demands on the performance of optoelectronic packaging materials. The increase in device power brings challenges in heat dissipation and high-temperature stability, while the improvement in integration density raises the risks of internal stray light interference and electrostatic discharge (ESD), directly affecting system reliability and signal-to-noise ratio. Traditional white alumina has limitations in optical control, and conventional ESD protection solutions often fail to be perfectly compatible with high gas-tightness and high thermal conductivity packaging systems.   Based on the high mechanical strength, thermal conductivity, and excellent insulation properties of black  alumina ceramics , the material achieves a multi-functional integration of optical control, thermal management, and on-chip electrostatic di...

The boron nitride evaporation boat (BN evaporation boat) is a high-temperature device made of high-purity hexagonal   boron nitride ceramics . It is usually in a boat shape or custom-made, and can hold various evaporation materials. During use, it not only serves as a container for holding molten materials but also maintains the cleanliness and stability of the working environment. Unlike ordinary ceramic components, the BN evaporation boat possesses both structural strength and chemical inertness, and can be used stably for a long time under extreme conditions.     The comprehensive advantages of materials and techniques   (1) Core material: High-purity hexagonal boron nitride   High-purity h-BN serves as the first line of defense to ensure process cleanliness. Its purity is ensured not to have any impurities precipitate at high temperatures, fundamentally eliminating the pollution caused by the vessel, maintaining extremely high purity of the evaporated materi...

  Ceramic Feedthroughs For Hermeticity and Electrical Isolation Application In aerospace, electrical and medical equipment applications, maintaining hermeticity and electrical isolation is critical. Ensuring a reliable seal against environmental contaminants while facilitating the transmission of electrical signals requires sophisticated solutions.  Ceramic feedthroughs  have emerged as indispensable components, offering unparalleled performance in achieving hermeticity and electrical isolation in demanding environments. Ceramic feedthroughs serve as conduits for electrical signals, allowing them to pass through barriers such as vacuum chambers, pressure vessels, or hermetically sealed enclosures while maintaining a tight seal against moisture, gases, and other contaminants. This benefits makes ceramic feedthroughs essential in applications where need the reliability and durability.   Innovacera ceramic-to-metal feedthroughs insulators are made by high purity alumina...

Powder metallurgy has core process advantages such as high material utilization, low unit energy consumption, and environmental protection. It is a technology that is in line with the future direction of carbon neutrality.   In recent years, with the maturity of powder metallurgy technology and the trend of miniaturization of parts, two emerging process routes, metal injection molding (MIM) and 3D printing (AM), have rapidly emerged.   At the same time, the supply of high-quality powder raw materials has begun to become a major factor restricting the development of the industry.   Small and complex parts are undoubtedly more suitable for injection molding and 3D printing (particle size of 20μm or even smaller), and have been increasingly used in high-end fields such as aerospace, medical, electronics, and military industry.   Therefore, the preparation of metal powders with high purity, good sphericity, small particle size and narrow distribution, and low oxygen cont...
