Hermetic Seal Success Stories from Tekna Seal

Tekna Seal, a custom manufacturer of hermetic seals, specializes in glass-to-metal hermetic seals. Our glass to metal seals are custom built to your design specifications, using our proprietary "Oxide-Free" hermetic sealing process.

We have helped so many businesses with their hermetic seal needs. Below are a few of our favorite success stories, highlighted for you. Hopefully you can join this list as well!

Tekna Seal Success Story 1:
Challenge: Vacuum pressure gauge requires leak rates less than 1 X 10¯10 std cc/sec Helium at 14.7 psi
Solution: Tekna Seal's proprietary oxide free sealing process for glass seals allows us to exceed this requirement without the expense of a ceramic-to-metal feedthrough.

Tekna Seal Success Story 2:
Challenge: Application required hermetic seal to retain pressure in excess of 25,000 psi
Solution: Tekna Seal helped the customer identify the failure mode in their existing design which allowed the customer to redesign their product to withstand test pressures significantly greater than the specification required.

Tekna Seal Success Story 3:
Challenge: Customer requires hermetic seals in titanium housing. Housing must be free and clear of additional oxide or nitride to be suitable for welding.
Solution: Tekna Seal's proprietary oxide-free hermetic sealing process in combination with silica-free glass creates a hermetic seal to titanium surface without additional oxide or nitride required.

Tekna Seal Success Story 4:
Challenge: Customer design requires higher current carrying capacity than standard glass seal pins allow without overheating.
Solution: Seals were made with Copper pins using newly available glass with a higher coefficient of thermal expansion than traditionally available glass materials.

Tekna Seal Success Story 5:
Challenge: Photonics manufacturer wishes to package a long attenuator crystal that has a coefficient of thermal expansion incompatible with the standard Kovar package material.
Solution: Glass-to-metal sealed packages using Metal-Injection-Molded housings with alloys custom tailored to the expansion rate of the crystal.

Tekna Seal Success Story 6:
Challenge: Application requires seals to withstand temperatures in excess of 500°C.
Solution: Seals were made using crystallizing ceramic glass. Crystals reinforce the glass allowing for reliability of the seal up to 600°C.

Tekna Seal Success Story 7:
Challenge: Interconnection requires keyed orientation integrated into the glass seal
Solution: A ceramic doped glass with a much higher working point temperature than the sealing glass allows for the key feature to be economically molded into shape.

Tekna Seal Success Story 8:
Challenge: Package geometry requires complex machined features in Kovar
Solution: The housing was manufactured as a molded package, eliminating the need for machining. This significantly reduced the cost of the package.

Tekna Seal Success Story 9:
Challenge: Customer's design required thick and thin sections incoporated into the stamped housing.
Solution: Tekna Seal manufactured the feedthru from two inexpensive stampings simultaneously brazed and glass sealed into a single robust assembly.

Tekna Seal Success Story 10:
Challenge: Customer requires a low thermal expansion die mount surface in a corrosion resistant stainless steel housing.
Solution: Tekna Seal's oxide free process allows us to simultaneously braze and glass seal, providing a low cost solution for combining dissimilar material properties.
