Package Seal

Natel has one of the most complete package seal areas in the industry. Just about any type of package or weld technique can be accomplished. Our newest addition to package seal is our automatic linear welding system. This system allows packages to be sealed by picking up, positioning, tack welding and then sealing the hybrid or module automatically. There are also manual linear weld systems, one-shot or induction weld systems and solder/eutectic seal systems.

  • Housed in a Class 1K clean room
  • 1 Fully automatic linear weld system
  • 5 Semi-automatic linear weld systems
  • 1 Linear hydrogen furnace cover seal system
