Abstract:
1. A method for manufacturing a reduced-hydrogen packaged electronic device that includes a hydrogen port, comprising the steps of providing an electronic device; providing a base; affixing the electronic device to the base; providing a cover, the cover including an aperture; welding the cover to the base to form a housing; degassing the assembly by heating to a temperature in the range of about 100–265° C. for a time sufficient to remove at least some hydrogen from the housing; then providing a hydrogen diffusion port for the aperture, the hydrogen diffusion port sized to be received by the aperture; and soldering the hydrogen diffusion port to the aperture to form a hermetically sealed solder joint, wherein the housing is characterized by an absence of plating applied to the base, the cover and the solder joint.
