The invention relates to a process for coating sintered cermet or cerglass articles with a metal or metal alloy. The process is particularly useful to eliminate pores and cavities from the surface of the article. During hermeticity testing, these pores and cavities trap tracer gas and result in an erroneous leak rate measurement. In one embodiment, the coated surfaces are subsequently coated with a second metal layer by immersion plating followed by electrolytic deposition. The process is particularly suited to the manufacture of cermet and cerglass components for semiconductor packages. |
