Glass-to-Metal Seals (GTMS)

• Hermetic Leak Rate: ≤ 1x10⁻⁸ Pa·m³/s (Strictly compliant with MIL-STD-883 requirements)
• CTE Matching Technology: Precision matching of Kovar (ASTM F-15) and custom alloys with specialized borosilicate glasses
• Seal Integrity: Continuous, void-free bond preventing micro-cracks during extreme thermal cycling
• Environmental Durability: Withstands cryogenic temperatures, high-temperature soldering, heavy vibration, and mechanical shock
• Chemical Resistance: Inert glass properties provide exceptional resistance to corrosion and chemical attack

• Aerospace & Defense: Hermetic connectors, sensor headers, and infrared detectors
• Medical Devices: Implantable device feedthroughs (e.g., pacemakers) and surgical tools
• Telecommunications: Optical communication packages (TO-Cans, butterfly packages) and RF feedthroughs
• Industrial Systems: Vacuum feedthroughs, high-pressure automotive sensors, and processing equipment
