Glass-to-Metal Sealing

Hermetic Solutions Group has over 70 years of experience in the glass-to-metal sealing industry supporting harsh environment microelectronics for the defense and aerospace, optical networking, medical, energy and industrial markets in applications such as satellite, missile, and aircraft guidance; electronic warfare; and the UAV market, as well as bio-medical detectors, fiber optic switching, blood analysis detectors and telecommunication technology.

If your application necessitates a glass-to-metal seal – we can make it happen!

We seal various types of glass directly into a variety of metals such as Kovar, Alloy 42, Alloy 49, Alloy 46, and stainless steel, with either a matched or compression seal. Machined, coined, etched, and stamped modules can be manufactured with pins directly glass-sealed into the module.

Through our extensive experience producing glass-sealed products - from connectors to microelectronic packages to headers and feedthrus, we have the expertise to deliver high-reliability glass-to-metal solutions. For applications requiring higher processing temperatures, we provide unique glass-to-metal seals which utilize a special oxidation and sealing process.

Brazing can often be performed before, during, or after the sealing process — depending on material choice. The Hermetic Solutions Group’s production lines including both blast furnaces, that take care of our glass-to-metal brazing sealing processes. We also offer vacuum brazing processes that use belt-furnace soldering for frames, floors, metallized ceramics, feedthrus, capacitors, connectors, etc. into housings, using Au/Ge, Au/Sn, and other tin alloys.

It is our top priority to help our customers address technical challenges and meet their business goals – let us help you!
