Abstract:
A multichip module comprises a multilayer substrate circuit having conductive patterns on its surface(s) to which microelectronic device(s) are attached. The conductive patterns include a series of electrical contacts adjacent to one edge of the substrate. The substrate is bonded to two rigid frames, one on each opposite surface. Each substrate has a series of castellations on one edge that are aligned and electrically connected to the respective contacts on the substrate, preferably by soldering. The castellations can serve as a self-aligning mechanism when the module is brought into contact with a low-profile pin array, and the module may be held in place on a motherboard by guide rails in a socket that engages the edges perpendicular to the castellated edge of the module. The module may further be provided with protective heat spreading covers.
Abstract:
A circuit carrier assembly includes a plurality of substrates directly secured together by an electrically conductive securing substance. In one example, the securing substance is a conductive epoxy. In another example, the electrically conductive securing substance is solder. Still another example includes a combination of solder and conductive epoxy. A non-conductive epoxy provides further mechanical connection and thermal conductivity between the substrates while also electrically isolating selected portions of the substrates in one example. The electrically conductive securing substance not only mechanically secures the substrates together and provides thermal conductivity between the substrates, which increases the thermal capacitance of the assembly, but also establishes at least one electrically conductive path between the substrates.
Abstract:
A multichip module comprises a multilayer substrate circuit having conductive patterns on its surface(s) to which microelectronic device(s) are attached. A part of the substrate is flexible and bifurcated. Two rigid members are attached lengthwise, one on either side of the substrate, and the free ends of the bifurcation are reflexed respectively about these members and bonded to them. Electrodes are located on the bifurcations so that they will be exposed outwardly and/or downwardly after reflexing. The module may further be provided with protective heat spreading covers. The electrodes and rigid members may be configured to engage a mating socket or they may be solderable to a printed circuit board.
