Abstract
A method for fabricating a leadframe with encapsulant guide is provided, including forming a die attach paddle. Leads are formed around at least portions of the die attach paddle, and encapsulant guides are formed angled on a plurality of the leads to push the leads outwardly when an encapsulant flows therepast.
