Abstract

A metal package for housing an electronic device wherein the electronic device is attached to a severable die attach pad. The die attach pad is bonded to the base of the package with a thermally conductive medium. The base is bonded to the die attach pad and to the leadframe at the same time to reduce the thermal degradation of the sealants. In other embodiments, apertures are provided in the base component to enhance cooling of the electronic device and in the cover component to vent reaction by-products.
