    Abstract: The present invention discloses a face-to-face (FTF) stacked integrated circuit (IC) assembly. The FTF stacked IC assembly includes a first and a second substrate-on-bare-chip (SOBC) modules. Each of the first and second SOBC modules includes a printed circuit board (PCB) having a PCB bottom surface overlying an active circuit surface of a bare integrated circuit (IC) chip. The PCB includes a window opened substantially in a central portion of the active circuit surface of the bare IC chip. The bare IC chip includes bare-chip bonding-pads disposed on the active circuit surface in the window and the PCB includes a plurality of PCB bonding pads. Each of the first and second SOBC modules includes a plurality of bonding wires interconnecting the bare-chip bonding pads to the PCB bonding pads. Each of the first and second SOBC modules includes a plurality of solder balls disposed on a PCB top surface of the PCB connected to the PCB bonding pads with a plurality of metal traces disposed on the PCB board. The solder balls of first SOBC module mounted on the solder balls of the second SOBC module constituting a face-to-face (FTF) stacked SOBC assembly.

    Abstract: A pad array electronic device for mounting on a substrate, such as a printed circuit board (PCB), has a relatively rigid package body with a plurality of holes bearing connecting mechanisms for bonding to lands on the PCB. The package body may be a thermoset plastic or other material that can be injection molded around an electronic component, such as an integrated circuit (IC) bonded to a lead frame. An integrated circuit die or other electronic component is mounted in proximity with or on the lead frame and electrical connections between the integrated circuit chip and the frame are made by any conventional means. In one aspect, the substrate leads are provided at their outer ends that are exposed by holes in the package with solder balls or pads for making connections to the PCB. The package body may be optionally used to stand off the device a set distance from the PCB so that the solder balls will form the proper concave structure. The periphery of the package body may function as a carrier structure to protect the lead or connection structures during testing, handling and board mounting. The open vias permit back side testing of the device before or after mounting of the package to the PCB. Additionally, a heat sink structure and/or capacitor may be directly bonded to the side or the top of the pad array electronic device which may be used singly or in multiple, stacked configurations, to facilitate the thermal dissipation from the device.
