摘要:
A circuitized substrate which utilizes an underlying conductive layer coupled to a pad on the substrate to assure a reinforced pad which will not be damaged or removed from the substrate when subjected to a significant load. Two or more pads can be similarly provided and coupled to the conductive layer, e.g., the layer being a common (ground) layer. An information handling system (e.g., a personal computer) utilizing the substrate is also provided.
摘要:
A multilayered PCB including two multilayered portions, one of these able to electrically connect electronic components mounted on the PCB to assure high frequency connections therebetween. The PCB further includes a conventional PCB portion to reduce costs while assuring a structure having a satisfactory overall thickness for use in the PCB field. Coupling is also possible to the internal portion from these components. Methods of making these structures have also been provided.
摘要:
A multi-chip electronic package which utilizes an organic, laminate chip carrier and a plurality of semiconductor chips positioned on an upper surface of the carrier. The organic, laminate chip carrier is comprised of a plurality of conductive planes and dielectric layers and couples the chips to underlying conductors on the bottom surface thereof. The carrier may include a high-speed portion to assure high-frequency connection between the semiconductor chips and may also include an internal capacitor and/or thermally conductive member for enhanced operational capabilities.
摘要:
A multi-chip electronic package which utilizes an organic, laminate chip carrier and a pair of semiconductor chips positioned on an upper surface of the carrier in a stacked orientation. The organic, laminate chip carrier is comprised of a plurality of conductive planes and dielectric layers and couples one or both of the chips to underlying conductors on the bottom surface thereof. The carrier may include a high-speed portion to assure high-frequency connection between the semiconductor chips and may also include an internal capacitor and/or thermally conductive member for enhanced operational capabilities. The first chip, e.g., an ASIC chip, is solder bonded to the carrier while the second chip, e.g., a memory chip, is secured to the first chip's upper surface and coupled to the carrier using a plurality of wirebond connections.
