Technical Specifications

Process Capabilities

  • 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

Applications

  • 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
