摘要： A method, system and apparatus for coating plated through holes (PTHs) to reduce impedance discontinuity in electronic packages. PTH vias are imbedded in the core of a printed circuit board comprising a core layer, a plurality of buildup layers, a plurality of micro-vias, and a plurality of traces. Traces electrically interconnect each of the micro-vias to PTH vias, forming an electrically conductive path. PTHs are coated with a magnetic metal material, such as nickel, to increase the internal and external conductance of the PTHs, thereby providing decreased impedance discontinuity of the signals in electronic packages.

摘要： Systems and methods for reducing switching noise in an integrated circuit. In one embodiment, decoupling capacitors are connected to the integrated circuit from the underside of the substrate on which the integrated circuit die is manufactured. The decoupling capacitors are positioned with a higher concentration in the “hot spot” areas of the integrated circuit instead of being evenly distributed. In one embodiment, the decoupling capacitors and the corresponding hole(s) in a circuit board on which the integrated circuit is mounted are positioned so that the circuit board provides support for the central portion of the integrated circuit and thereby prevents the integrated circuit from flexing away from the heat sink/spreader. In one embodiment, the concentration of vias connecting the different ground planes and/or power planes within the integrated circuit is higher in hot spots than in other areas.

摘要： An electronic package including a conductive trace layer having a first side and a second side. The conductive trace layer is patterned to define a plurality of interconnect pads. A flexible dielectric substrate is mounted on the first side of the conductive trace layer. A flexible capacitor including a first conductive layer, a second conductive layer and a layer of dielectric material disposed between the first and the second conductive layers is mounted with the first conductive layer adjacent to the second side of the conductive trace layer. A plurality of interconnect regions extend through the first conductive layer and the dielectric material layer of the capacitor. An interconnect member is connected between each one of the conductive layers of the capacitor and a corresponding set of the interconnect pads. The first conductive layer of the capacitor is electrically connected to a first set of the interconnect pads and the second conductive layer of the capacitor is electrically connected to a second set of the interconnect pads. The interconnect members corresponding to the second set of interconnect pads extend through one of the interconnect regions. An aperture extends through the dielectric substrate adjacent to each one of the interconnect pads. A stiffening member is mounted adjacent to the second conductive layer of the capacitor. A device receiving region is formed through the dielectric substrate, the conductive trace layer and the capacitor.

摘要： A low-cost integrated circuit package is provided for packaging integrated circuits. In preferred embodiments, the package comprises a flexible circuit that is laminated to a stiffener using a dielectric adhesive, with the conductive traces on the flexible circuit facing toward the stiffener but separated therefrom by the adhesive. The conductive traces include an array of flip-chip attachment pads. A window is formed in the stiffener over the attachment pad array, such as by etching. The adhesive is then removed over the attachment pads by laser ablation, but left in place between the pads, thus forming a flip-chip attachment site. In preferred embodiments, this invention eliminates the need for high-resolution patterned adhesive, and it also eliminates the need for application of a solder mask at the flip-chip attachment site, because the remaining adhesive performs the solder mask function of preventing bridging between attachment pads. This package provides a die attachment site having a high degree of planarity due to tensile stresses formed in the flexible circuit and adhesive layers during lamination of those layers to the stiffener. Embodiments of this invention may be used with TBGA, frangible lead, and other packaging technologies.
