Hermetic Seal Basics

Hermetic seals provide a moisture-tight, airtight, barrier between environments. Tekna Seal hermetic feedthroughs provide a means to transfer electrical or optical signals from one sealed environment to another. Examples: packages for microelectronic sensors used in harsh media, terminals for batteries using chemistries that are sensitive to water vapor, windows for imaging electronics used in severe environments.

Glass seals provide a economical approach for most feedthroughs. The Tekna Seal proprietary oxide-free glass-to-metal hermetic seal process eliminates the need for pre-oxidizing of the metal components prior to glass sealing. This lack of heavy oxide interface between glass and metal allows for:

  • Increased pressure withstanding
  • Higher levels of hermeticity
  • Repeatable, reliable processing

Eliminates the need for post oxide removal:

  • Glass and metal are clean, free of etching residue
  • Hazardous waste stream eliminated

Ceramic seals can be used in high temperature, high voltage or applications requiring biocompatible materials for implantable devices.

Hermetic windows are found in applications for optical switching, scientific cameras and photosensitive sensors.
