Lead assembly could include glass sealing and/or brazing of the leads, gold plating of the box, and surface grinding of the box. However, there is a lack of information on the hermeticity of the MIM material. This information is necessary for industry use of MIM metals and parts. The research examined the hermeticity of MIM boxes produced from 316L stainless steel, 49% Nickel-Iron, and ASTM F- 15. Furthermore, limited testing was conducted on packages that were gold plated, machined, and glass sealed prior to hermeticity testing. In all cases, the hermeticity of the box were better than the industry standard. Therefore, MIM can be used to produce the box, a cost savings of 60% or greater can be realized.
