Method of manufacturing a packaged circuit including a lead frame and a laminate substrate
Embodiments of the subject application provide for a circuit comprising: a lead frame having a first plurality of exposed terminals, the lead frame defining a plane; a laminate substrate in the plane defined by the lead frame, adjacent to the lead frame, and electrically coupled to the lead frame, the laminate substrate having a first surface including a second plurality of exposed terminals and a second surface opposite the first surface; a first one or more dies mounted on the lead frame and electrically coupled to the lead frame; and a second one or more dies mounted on the second surface of the laminate substrate and electrically coupled to the laminate substrate.
1. A method of manufacturing a circuit comprising:
placing a lead frame and a laminate substrate on a temporary holding structure such that the lead frame and the laminate substrate are adjacent to one another in the same plane;
attaching one or more first dies to the lead frame and one or more second dies to the laminate substrate;
attaching one or more interconnect mechanisms to one or more of the lead frame, laminate substrate, the one or more first dies, and the one or more second dies;
encapsulating the one or more first dies, the one or more second dies, the lead frame, and the laminate substrate; and
removing the temporary holding structure.
2. The method of claim 1 , wherein placing the lead frame and the laminate substrate includes aligning one or more side terminals of the lead frame with corresponding pads on a surface of the laminate substrate; and
attaching the one or more side terminals of the lead frame to the laminate substrate using a die attach compound.
3. The method of claim 1 , wherein attaching one or more interconnect mechanisms includes attaching an interconnect mechanism to an internal surface of the lead frame and to an internal surface of the laminate substrate to couple the lead frame to the laminate substrate.
4. The method of claim 1 , wherein the temporary holding structure comprises adhesive tape.
