ABSTRACT:
A leadframe includes a leadframe finger support for supporting elongate leadframe fingers. These elongate leadframe fingers are subject to damage prior to or during the assembly process. Through the provision of the leadframe finger support, the leadframe fingers may be supported at an intermediate position along their length as necessary to prevent bending. The support may be severed from the dam bar in the course of singulation.
