Titanium-Aluminum (TAP) Hermetic Microwave Packaging CASE STUDY Customer Challenge A customer who manufactures aircraft radar systems requested that the hermetic packaging for its Integrated Microwave Assembly (“IMA”) be constructed of a material that has high thermal conductivity, has low coefficient of thermal expansion (“CTE”), and is lightweight. Thermal conductivity is the ability of a material to allow the flow of heat from its warmer surface to its colder surface, whereas CTE is the tendency of materials to change in volume in response to a change in temperature. Challenge Review Although the ideal hermetic microwave packaging material used in aircraft radar systems would be lightweight, have low CTE and high thermal conductivity, no standard materials exist that contain a
