Abstract:
1. A method for manufacturing an electronic assembly, comprising the steps of: providing a mold having a first mold portion and a second mold portion, wherein the first and second mold portions each include a cavity, and wherein the first mold portion includes a plurality of spaced mold pins extending from an inner surface, where the cavity of the first and second mold portions provides a mold cavity when joined; providing a backplate, the backplate having a plurality of support pedestals and an integrated heatsink extending from a first side of the backplate; providing a substrate with a first side of an integrated circuit (IC) die mounted to a first side of the substrate, wherein the IC die is electrically connected to one or more of a plurality of electrically conductive traces formed on the first side of the substrate; placing the backplate and the substrate within the cavity of the second mold portion, wherein a second side of the backplate is in contact with an inner surface of the second mold portion, and wherein a second side of the die is in thermal contact with the heatsink and the support pedestals are in contact with the first side of the substrate, where the first side of the IC die is opposite the second side of the IC die; joining the first and second mold portions, wherein the mold pins contact a second side of the substrate, and wherein the second side of the substrate is opposite the first side of the substrate; and filling the mold cavity with an overmold material to provide an overmolded electronic assembly that includes the substrate, the backplate and the overmold material.
