Hermetic Ceramic Brazing Components
Hermetic ceramic brazing components are designed to prevent gas and moisture penetration through the ceramic-metal interface. They are particularly important in systems where leakage can compromise vacuum stability, insulation, or component lifetime.
Key Features
- Hermetic ceramic-metal sealing
- Low leakage performance
- High electrical insulation
- High-temperature resistance
- Long-term environmental stability
Materials
Alumina is commonly used ceramic materials, while Kovar, stainless steel, copper, and other compatible metals can be selected for the metal side.
Quality Control
Hermetic assemblies can be evaluated using helium leak testing, while mechanical and dimensional inspection can be applied according to the project requirements.
Applications
Typical applications include vacuum feedthroughs, electronic packages, semiconductor equipment, X-ray tubes, high-voltage assemblies, and medical devices.
If your project has a specific helium leak-rate requirement, include the target value with your drawing so the sealing structure can be reviewed accordingly.
