Leadframe with die pad having cantilevers to secure electronic component

Abstract:

A leadframe includes a die pad having a plurality of sides which collectively define the rectangular die pad area including at least two securing sides that include a linear portion with a cantilever interrupting the linear portion. The die pad has a top surface defining a top plane and a bottom surface defining a bottom plane. Lead terminals are beyond the die pad. The cantilevers have a fixed end and a free end opposite the fixed ends that enables flexing or bending responsive to a received force. The free ends include a distal end with an electronic component locking feature. The fixed ends are positioned beyond the die pad area, and the electronic component locking feature extends inward over the rectangular die pad area for providing mechanical support and for securing the electronic component.
