In thermal treatment scenarios such as high-temperature vacuum sintering, annealing, and melting, the equipment needs to endure long-term exposure to high temperatures, vacuum, inert atmospheres, and repeated thermal cycles under harsh conditions. Traditional furnace materials are prone to thermal shock cracking, workpiece adhesion, and contamination issues, which not only shorten the equipment’s lifespan, increase maintenance costs, but also affect the appearance and dimensional accuracy of the workpieces, and fail to meet the requirements of high-end manufacturing such as semiconductors, precision ceramics, and special metals. However, boron nitride (BN) ceramics are resistant to high temperatures, chemically stable, non-stick, and highly clean. They are currently the core high-quality functional materials for high-temperature vacuum furnaces and thermal treatment equipment.   I.

Why AlN Ceramic Substrates Are Used in Optical Modules

By -
Image
With the rapid development of AI computing power, cloud computing, and data center networks, optical communication systems are continuously evolving toward higher bandwidth. As data transmission rates increase from 400G to 800G and up to 1.6T, power density is also rising significantly. Under these circumstances, thermal management within optical modules has gradually become one of the key factors affecting performance stability and long-term reliability. Due to its excellent thermal conductivity and electrical insulation properties, aluminum nitride (AlN) ceramic substrates are emerging as a critical material choice for high-speed optical module packaging.     01 Industry Insight: High-Speed Optical Modules Are Driving the Upgrade of Packaging Materials   In recent years, AI data centers and high-speed communication networks have continued to expand, pushing optical modules rapidly from 100G/200G toward 400G, 800G, and even 1.6T. As data rates increase, internal integrat...

Microporous Ceramic Vacuum Chuck for Semiconductor Manufacturing: Ceramic-Metal Hybrid Design

By -
Image
In the fields of semiconductor, optics, and high-precision electronic manufacturing, stable workpiece clamping and damage-free transfer have always been critical process steps. As process precision continues to improve, the limitations of traditional porous metal vacuum chucks in terms of uniformity, cleanliness, and long-term stability have become increasingly evident, driving the development and application of a new generation of ceramic-metal composite micro-porous vacuum chucks.   This type of vacuum suction cup typically uses high-performance microporous ceramic as the adsorption functional layer, integrated with a metal flange base structure in a unified design to achieve synergistic optimization of performance and structural strength.   01 The Key Role of Micro-porous Ceramic Adsorption Surface   On the adsorption end face, the product employs high-purity alumina (Al2O3) or silicon carbide (SiC) micro-porous ceramic materials, which are precisely sintered to form a...
