ABSTRACT:
An electrical device package includes an aluminum header having a gold-coated sealing surface and an electrical device mounted within the boundary defined by the sealing surface. An annular gold-coated stainless steel seal ring registers with the sealing surface of the header. An annular bonding layer of a gold-tin alloy lies between, and registers with, the sealing surface of the aluminum header and the stainless steel seal ring. The electrical device is fastened to the header using an electrically and thermally conductive epoxy adhesive. A stainless steel cover has a flange which is welded to the seal ring to form a hermetically sealed package.
