What is a setter plate?   A setter plate is a high-temperature support Boron Nitride Square Crucibles used inside a sintering furnace to hold ceramic substrates during firing. It helps maintain dimensional stability, minimizes deformation, and prevents contamination throughout the sintering cycle.   In AlN Substrate and Si3N4 Substrate manufacturing, the setter plate is not only a “supporting tool” but also a critical process component that directly affects material purity, sintering uniformity, and yield.   Especially in the sintering process of aluminum nitride and silicon nitride substrates, extremely high requirements are placed on the setter plate material: it must not contaminate the material system and must withstand high temperatures, atmosphere changes, and long-term thermal cycling.     Why is the setter plate so critical in AlN/ Si3N4 sintering?   AlN and Si3N4 are typical “highly sensitive structural ceramics,” whose properties are extremely se...

Against the backdrop of semiconductor manufacturing, vacuum optical experiments, and high-end industrial equipment continuously advancing toward higher precision and stability, internal system signal transmission methods are undergoing significant upgrades. Particularly in high-vacuum and ultra-high-vacuum (UHV) environments, achieving stable, leak-free, and low-loss optical signal introduction and transmission has become one of the key technical challenges.   Ceramic-to-metal brazing technology, as an advanced hermetic sealing solution, is becoming a key foundational process for high-reliability vacuum electronic and optical components. Among these applications, optical fiber vacuum feedthrough s represent a significant example of this technology in the field of precision optical transmission.   I. Technical Challenges in High-Vacuum Optical Signal Transmission   Traditional vacuum system designs face significant hurdles when routing fiber-optic signals from atmospheric ...
