    摘要: A method and structure for implementing dense wiring, in printed circuit board or chip carrier applications, which provides superior electrical characteristics while preserving the system resistance and characteristic impedance requirements. The dense wiring is characterized by requiring that all wires have a sufficient cross-sectional area to ensure the longest wires used do not exceed a maximum resistance by either sorting wire lengths and allowing acceptably “short” wires to use denser circuit lines or by providing short lengths of short circuit lines in those areas where necessary and switching to less dense, lower resistance lines where possible. The disclosure also provides for dense wiring in component areas that can then be converted to low resistance wiring with application of a buried via.

    摘要: A method of making a printed circuit board in which the board includes a common power plane having dielectric layers on opposing sides thereof and a signal layer on each of said dielectric layers, each signal layer comprising a plurality of substantially parallel signal lines running in substantially similar directions across said signal layers. Predetermined portions of the signal lines in one signal layer are aligned relative to and also parallel to corresponding signal lines in the other signal layer, with the power plane being located between these portions. Through hole connections are provided between selected signal lines in the two layers, these occurring through clearance holes in the power plane so as to be isolated therefrom.

    摘要: An electrical assembly which includes a circuitized substrate including a first plurality of dielectric and electrically conductive circuit layers alternatively oriented in a stacked orientation, a thermal cooling structure bonded to one of the dielectric layers and at least one electrical component mounted on the circuitized substrate. The circuitized substrate includes a plurality of electrically conductive and thermally conductive thru-holes located therein, selected ones of the thermally conductive thru-holes thermally coupled to the electrical component(s) and extending through the first plurality of dielectric and electrically conductive circuit layers and being thermally coupled to the thermal cooling structure, each of these selected ones of thermally conductive thru-holes providing a thermal path from the electrical component to the thermal cooling structure during assembly operation. The thermal cooling structure is adapted for having cooling fluid pass there-through during operation of the assembly. A method of making the substrate is also provided.
