METHOD OF MANUFACTURING ELECTRICAL FEEDTHROUGH INCLUDING PROCESSES FOR REDUCING STRESS IN PACKAGES HAVING A HIGH-CTE METAL AND LOW-CTE SEALING MATERIAL INTERFACE
20190027914 · 2019-01-24 ·

Methods for use in the manufacture or assembly of an electrical feedthrough to provide a solution to the technical and operational challenges that may arise from use of a high-CTE metal/low-CTE sealing material based assembly or package. In some embodiments, the inventive method includes a thermal tempering and thermal quenching process that is used to create an interfacial layer of the sealing material in which there exists a CTE gradient from sealing material to the metal shell and pin(s). This enables the production of an electrical feedthrough assembly that can tolerate high-CTE mismatch induced mechanical stress over a wide operating temperature range.
