Glass to Metal Sealing

Glass to metal and glass to glass sealing involves the softening or melting of glass and subsequent wetting to glass or metal surfaces to form a seal that is hermetic and electrically insulated. Glass to metal seal types may be either matched or compression. Creating these seals requires careful control of surface oxides, together with thermal sealing and annealing profiles with temperatures as high as 1000°C. SST has over fifty years of experience with equipment, fixturing and processes which precisely align and seal glass assemblies. Typical applications include discrete glass diodes, hermetic feed-thrus, EMI filters and surge suppressors.
