    摘要: A test method characterizes current behavior of power components (e.g., semiconductor packages) within an electronic system. One or more electrically conductive loops are formed with a first printed circuit board of the electronic system; these loops surround, at least in part, one or more electrical vias of the first printed circuit board. One or more power components connect to the vias to obtain power therethrough. Current characteristics are measured from one or more vias to assess transient and steady-state currents of components within the system. Power dissipation may be determined from the current. The loops may be formed within tracks of internal layers of the first printed circuit board, or a second printed circuit board may form the tracks.

    摘要: A high performance processor assembly is electrically connected to a power supply so as to minimize voltage variations associated with the supply of power to the processor assembly. The processor assembly is fabricated on a multilayered printed circuit board. Power is supplied to components on the printed circuit board by way of parallel and split power planes. The parallel and split power planes reduce inductance and increase capacitance associated therewith. The reduced inductance reduces voltage variations caused by load transient currents. Capacitors are electrically connected to the power planes by way of multiple vias to further reduce inductance.
