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.
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.
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.
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.
Challenge: Pins must provide corrosion resistance without plating.
Solution: Hermetic seals were made with stainless steel pins using newly available glass with a higher coefficient of thermal expansion than traditionally available glass materials.
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.
