As an alternative to Kryoflex®, we can provide glass-to-metal seals to reduce the cost of manufacturing, or when glass performance is required for the specific application.
Glass Hermetic Seals
Glass can be directly sealed into a variety of metals such as Kovar, Alloy 42, Alloy 49, Alloy 46, and Stainless Steel, in either a matched seal or compression seal to meet customer requirements. Machined, Coined, Etched, and Stamped modules can be glass sealed depending on customer needs and cost considerations. Hi-REL (High-Reliability) glass-to-metal seals, which utilize a special oxidation and sealing process, are also manufactured for those applications requiring higher processing temperatures.
Brazing of materials can often be performed before, during, or after the sealing process — depending on material choice. The brazing process utilizes belt furnace technology to ensure smooth braze joints. Brazing can be done to a variety of metals such as Cu/W, Copper, and Iron-Nickel Alloys. Any of these combinations of metals can be brazed together to provide our customer with flexible solutions.
Soldering of frames, floors, metallized ceramics, feedthrus, capacitors, connectors, etc. into housings using Au/Ge, Au/Sn, and other Tin alloys (depending on processing temperature requirements) can also be produced for value added manufacturing. A variety of metal combinations can be soldered together to provide packaging with soldered hermetic seals.
