ABSTRACT:
To hermetically seal an optically transparent ceramic or glass member to a metallic housing, an aperture with a diameter less than the diameter of the member is formed through the metallic housing. The member is then press-fit into the aperture, partially displacing metal from the walls of the aperture, forming an inner burr circumscribing the aperture. The walls of the aperture and the circumscribing burr are then coated with a second metal, preferably electroless nickel. The resultant seal maintains hermeticity following thermal cycling and is particularly suited for the manufacture of a hybrid electronic package having an optical or opto-electronic coupling.
