Abstract

An electronic package which includes at least two flexible circuitized substrates (e.g., thin film elements) connected at one location to a common first circuitized substrate (e.g., printed circuit board) and at another location to a semiconductor device, these subassemblies being located within a base member of the package. In one embodiment, a singular heat sink member is thermally coupled to a respective one of the semiconductor devices, and a common, second heat sink member is thermally coupled to all of the first heat sink members. This common heat sink member also uniquely serves as a stiffener for the package. In another embodiment, a common heat sink member is securedly positioned on the opposite side of a first circuitized substrate from the plurality of flexible circuitized substrates and semiconductor devices. A base member is also used as part of this package. As in the aforementioned other embodiment, the common heat sink member also serves as a stiffener.
