    摘要: A circuit board having a structure including a permanent photoimageable dielectric material suitable for fabrication of vias both by laser ablation, plasma ablation, or mechanical drilling techniques and by photoimaging techniques. A process is also disclosed for the manufacture of a multi-level circuit on a substrate having a first-level circuitry pattern on at least one side. The process comprises applying a permanent photoimageable dielectric over the first-level circuitry pattern; exposing the permanent photoimageable dielectric to radiation; laminating a conductive metal layer to the dielectric; making holes in the conductive metal layer and dielectric by mechanical drilling or by laser or plasma ablation; and making a second-level circuitry pattern and filling the holes with a conductive material to electrically connect the first and second layers of circuitry. A further process is claimed for designing a multi-level circuit board product comprising making a prototype having the above structure in which the holes are manufactured by mechanical drilling or by laser or plasma ablation, evaluating the prototype, and then manufacturing a commercial circuit board having essentially the same structure and materials of construction as the prototype, but wherein the holes are manufactured by photoimaging techniques.

    摘要: A multilayer chip carrier with increased space for power distribution PTHs and reduced power-related noise. In a multilayer chip carrier with two signal redistribution fanout layers, in addition to signal escape from near-edge signal pads at the first fanout layer, remaining signal pads are moved closer to the edge of the chip footprint. At the voltage layer below the first fanout layer, the remaining signal pads are moved again, closer to the edge of the chip footprint. In the second fanout layer, below the voltage layer, the remaining signal pads escape. The region where signal pads are moved provides increased space for power PTHs.

    摘要: A circuitized substrate designed to substantially eliminate impedance disruptions during passage of signals through signal lines of the substrate's circuitry. The substrate includes a first conductive layer with a plurality of conductors on which an electrical component may be positioned and electrically coupled. The pads are coupled to signal lines (e.g., using thru-holes) further within the substrate and these signal lines are further coupled to a second plurality of conductive pads located even further within the substrate. The signal lines are positioned so as to lie between the substrate's first conductive layer and a voltage plane within a third conductive layer below the second conductive layer including the signal lines. A second voltage plane may be used adjacent the first voltage plane of the third conductive layer. Thru-holes may also be used to couple the signal lines coupled to the first conductors to a second plurality of conductors which form part of the third conductive layer. A method of making the substrate, and an electrical assembly and information handling system (e.g., computer) utilizing the substrate are also disclosed.

    摘要: The escape of signals from a semiconductor chip to a printed wiring board in a flip chip/ball grid array assembly is improved by repositioning the signals from the chip through the upper signal layers of the carrier. This involves fanning out the circuit lines through the chip carrier from the top surface that communicates with the chip through the core to the bottom surface where signals exit the carrier to the printed wiring board, which is achieved by making better utilization of the surface area of the signal planes between the core and the chip. The signals are fanned out on each of the top signal planes so that many more of the signals are transmitted through the vias in the core to the bottom signal planes where they can escape outside of the footprint area of the chip, thereby increasing the density of circuits escaping the footprint area.
