Abstract
A non-magnetic hermetic package includes walls that surround an open cavity, with a generally planar non-magnetic and metallic seal ring disposed in a continuous loop around upper edges of the walls; a sensitive component that is bonded within the cavity; and a non-magnetic lid that is sealed to the seal ring to close the cavity by a metallic seal.

A non-magnetic hermetic package comprising:
- a package body comprising a floor and a wall extending upward from the floor;
- a seal ring extending around an upper edge of the wall, the seal ring consisting of non-magnetic metallic elements;
- a lid;
- a hermetic seam seal between the lid and the seal ring;
- and
- a sensitive component disposed within a hermetically-sealed cavity defined between the package body and the lid.
