Feedthrough technology

MST offers the development and manufacture of customer-specific feedthroughs for implants or sub-assemblies requiring hermetically sealed interfaces.

Three base technologies are available for countless solutions.

Ceramic-to-metal feedthroughs

  • typical application: medtech implants such as pacemakers, defibrillators or neurostimulators
  • material compositions: Ti/Al2O3/Nb or Ti/Al2O3/PtIr
  • geometry: circular or linear
  • unipolar to multipolar pin configurations
  • contacting through welding or soldering
  • filtered versions on request

Glass-to-metal feedthroughs

  • typical application: batteries for implants
  • material compositions: 304L/FeNi52 or 304L/Mo
  • unipolar to multipolar pin configurations
  • contacting through welding or soldering

Hybrids: glass/ceramic-to-metal feedthroughs

  • typical application: sensors or high-vacuum components
  • customized material compositions
  • unipolar to multipolar pin configurations
  • contacting through welding or soldering

The core areas of expertise for developing and manufacturing hermetic feedthroughs include:

  • materials science
  • design and process engineering
  • wet chemical conditioning
  • high-vacuum metallization (sputtering)
  • high-temperature/high-vacuum soldering of glass
  • high-temperature soldering using gold
  • resistance welding
  • micro sandblasting
  • assembly
  • mechanical and physical testing of components and materials
  • hermeticity testing
  • visual inspection
