Challenge: This defibrillating resonating oscillator was growing in volume requirements. Traditionally machined because of low quantities, challenges to reduce cost while maintaining precision, hermiticity, and the same co-efficiency of thermal expansion were presented to FloMet.Solution: A CTE tailored Fe Ni feedstock was developed for the application. The customer and FloMet worked together to create a part with minimum weight. No machining, incorporation of additional features that had been separate assembly parts attained a superior level of Tekna Seal finished hermeticity.Telecommunication and other microelectronic devices need to be protected by being sealed in a hermetic package. This housing is used in a microwave telecom application. It was originally developed by machining of a popular Fe 49% Ni alloy. The material is expensive to throw away chips, and is “tough and gummy” to machine also.
