A flexible flat circuit cable includes first and second flexible circuit substrates extending in an extension direction. The first flexible circuit substrate has a first surface forming a first conductor layer and an insulation layer, and the second flexible circuit substrate has a first surface forming a second conductor layer and an insulation layer. A bonding material layer is applied at a predetermined section between the first flexible circuit substrate and the second flexible circuit substrate to bond the first and second flexible circuit substrates together in such a way to maintain a predetermined spacing distance between the first and second flexible circuit substrate and forming a gapped segment at sections where no bonding material is applied. The first and second flexible circuit substrates form a cluster section within the gapped segment, which has opposite ends respectively forming first and second connected sections each of which forms a connection plug or is provided with a connector.
Abstract:
A multichip module comprises a flexible circuit having conductive patterns on its surface(s) to which microelectronic device(s) are attached. The flexible circuit is enclosed and supported by two rigid frames, which may further be provided with protective heat spreading covers. Contact pads on the rigid frame(s) may be configured to engage a mating socket or they may be solderable to a printed circuit board.
Abstract:
A flexible circuit comprises a folded dielectric sheet having conductive patterns on its surface(s) to which microelectronic device(s) are attached. The dielectric sheet is folded 180° about a selected axis and a bond layer joins the two halves over a portion of their respective surface areas so that a remaining portion of their areas remain unbonded and a bifurcated structure is thereby formed. Electrical contacts are provided on the unbonded or bifurcated portions of the flexible sheets. The flex may be attached to a rigid frame and provided with protective heat spreading covers. The folded flex design is particularly suitable for reel-to-reel manufacturing.
