Hermetic Lid Sealing
FLI offers hermetic lid sealing services for many packaging schemes such as TO can, Kovar, and ceramic. Sealing can be done utilizing resistive heating in which parts are placed in a heated vacuum or other desired environment, or utilizing a belt furnace to heat the product in the desired environment. In both cases the lid and housing are pre-coated with solder preform. Fixture design is a key factor in this process and FLI possesses the machining capability in house to meet many of our fixturing needs quickly.
Sealed parts are carefully inspected and we can complete Gross and/or Fine Leak Check operations.
