Glass compression seals using low temperature glass

摘要

A metal housing is provided with lead in members by way of a compression seal using a glass that can be worked below about 480 DEG C. The housing and lead in members can be preplated in a low cost process to provide a suitable protective coating that is present under the glass after the seal is made. This obviates a post seal plating and therefore avoids the related problems. It also permits using aluminum as the housing material.
