Hermetic Lid Sealing
FLI offers lid sealing service for many packaging schemes. Sealing is done utilizing one of two methods. One method is using resistive heating in which parts are placed in a heated vacuum or other desired environment. The other method is 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.
