Abstract
This invention provides methods for processing of platinum metallized high temperature co-fired ceramic (HTCC) components with minimum deleterious reaction between platinum and the glass constituents of the ceramic-glass body. The process comprises co-firing a multilayer laminate green ceramic-glass body with via structures filled with a platinum powder-based material in a reducing atmosphere with a specified level of oxygen partial pressure. The oxygen partial pressure should be maintained above a minimum threshold value for a given temperature level.
