Applications of Glass-to-Metal Feedthroughs and Hermetic Sealing
Glass-to-metal sealing (GTMS) is a critical technology used to create reliable, hermetic seals between glass and metal components. It is widely applied in industries that demand high performance, durability, and resistance to environmental stress.
Key Application Areas
1. Electronic Packaging
GTMS is commonly used to provide hermetic protection for sensitive electronic components, including:
- Vacuum tubes
- Transistors
- Pressure and optical sensors
These seals prevent gas and moisture ingress, enhancing long-term stability and performance.
2. Aerospace and Aviation
In aerospace applications, glass-to-metal feedthroughs are essential for sealing connectors and critical components exposed to extreme temperatures, pressure, and vibration. Typical use cases include:
- Sealed connectors
- Sensor interfaces
- Avionics systems
3. Medical Devices
GTMS enables the manufacture of biocompatible, hermetically sealed medical implants such as:
- Pacemakers
- Neurostimulators
- Implantable sensors
Hermetic sealing ensures isolation from bodily fluids, preventing corrosion and ensuring device reliability.
4. Automotive Industry
In the automotive sector, glass-to-metal sealing is used in:
- Engine and transmission sensors
- Airbag initiators
- Battery monitoring systems
These components require excellent thermal stability and resistance to vibration.
Benefits of Glass-to-Metal Sealing
- Excellent hermetic sealing performance
- High resistance to temperature, pressure, and corrosion
- Ideal for high-density, compact designs
- Proven reliability in mission-critical industries
