Abstract
There is provided a base for an electronic package. The base includes a peripheral portion for a polymer adhesive and a central portion for one or more semiconductor devices. A lead support is adjacent the substrate and located between the peripheral portion and the central portion. When a polymer adhesive bonds a leadframe to the package base, the lead support prevents deflection of the inner lead tips.
