Method for manufacturing an overmolded electronic assembly

摘要

A technique for manufacturing an electronic assembly uses a mold (40) that has a first mold portion (44) and a second mold portion (42). The first mold portion (44) includes a plurality of spaced mold pins (46) extending from an inner surface. A cavity of the first and second mold portions (44,42) provides a mold cavity (111), when joined. A backplate (110) is also provided that includes a plurality of support pedestals (112) and an integrated heatsink (114) extending from a first side of the backplate (110). A substrate (102) includes a first side of an integrated circuit (IC) die (106A) mounted to a first side of the substrate (102). The backplate (110) and the substrate (102) are placed within the cavity of the second mold portion and the support pedestals (112) are in contact with the first side of the substrate (102). The first and second mold portions (44,42) are joined and the mold pins (46) contact a second surface of the substrate (102) during an overmolding process.
