  • the solder used is preferably a gold solder.
  • soldering methods can be used at gentle temperatures.
  • An active soldering which is carried out at about 900 ° C, can be omitted by the use of reclaimed metal layers.
  • the laborious handling of the workpieces, the use of complex tools and the labor-intensive and energy-intensive processes that are necessary for soldering processes with temperatures of about 900 ° C, can be omitted.
  • the window is stepped in its edge region.
  • the Staging of the window can also serve to optimize the installation of the window at the edge regions of a housing surrounding the sheath.
