A composite leadframe is provided. The leadframe comprises a rigid metal portion electrically interconnected to a flexible multi-layer portion. When sealed within an electronic package, the composite leadframe provides a higher lead density than achieved by rigid metal leadframes and better electrical and mechanical properties than achieved with flexible leads. The package may comprise a discrete base and cover component with the leadframe disposed between or a monolithic block of plastic encapsulating the electronic device and a portion of the leadframe. |
