Consistent with an example embodiment, there is a package assembly structure. The structure comprises a lead frame having a topside surface and an opposite under-side surface; the lead frame includes a die attach paddle, wherein a die attach region is defined on the opposite under-side surface. Pad landings surround the die attach region. A plurality of locking pins are arranged at predetermined locations about the die attach paddle, on the top side surface. The plurality of locking pins may be formed integrally in the lead frame and project upward from the top side surface.

Inter-connection of a lead frame with a passive component intermediate structure

Various aspects of the disclosure are directed to integrated circuit (IC) die leadframe packages. In accordance with one or more embodiments, a stainless steel leadframe apparatus has a polymer-based layer that adheres to both stainless steel and IC die encapsulation, with the stainless steel conducting signals/data between respective surfaces for communicating with the packaged IC die. In some embodiments, the apparatus includes the IC die adhered to the polymer-based layer via an adhesive, wire bonds coupled to the stainless steel leadframe for passing the signals/data, and an encapsulation epoxy that encapsulates the IC die and wire bonds.
