    Abstract: A printed circuit board is provided to suppress the generation of electromagnetic wave more efficiently by differentiating a signal layer and a ground layer according to a switching speed of a signal to process an electronic element. A printed circuit board(10) includes an external ground layer(11), an insulating material(12), a power layer(13), and at least one signal layer(15). The external ground layer is placed at any one layer among two most external layers. The signal layer is placed at the other layer among the two most external layers. The power layer is formed between the signal layer and the external ground layer. An electronic component having a relatively slow clock signal speed among the mounted electronic components is connected to the external ground layer and an electronic component having a relatively rapid clock signal speed is connected to an intermediate ground layer.

    Abstract: A DC bus for use in a power module has a positive DC conductor bus plate parallel with a negative DC conductor bus plate. One or more positive leads are connected to the positive bus and are connectable to a positive terminal of a power source. One or more negative leads are connected to the negative bus and are connectable to a negative terminal of a power source. The DC bus has one or more positive connections fastenable from the positive bus to the high side of a power module. The DC bus also has one or more negative connections fastenable from the negative bus to the low side of the power module. The positive bus and negative bus permit counter-flow of currents, thereby canceling magnetic fields and their associated inductances, and the positive and negative bus are connectable to the center portion of a power module.

    Abstract: A printed circuit board intended for mounting at least one integrated circuit (1) and associated decoupling capacitors (21, 22) on the same surface of the printed circuit board. The printed circuit board comprises a stack of alternate conductive and insulating layers (81-87). One of the conductive layers (81) is arranged as a first power plane. The other conductive layers (83, 85, 87) are patterned and provided with signal tracks (831, 851, 871, 872). The stack of layers includes contact holes (91, 92) connected to the first power plane (81), which are arranged for being connected to decoupling capacitors (21, 22). At least one (83) of the patterned conductive layers locally provides at least one second power plane (833) under that part of the aforesaid surface of the printed circuit board which is arranged for mounting an integrated circuit (1) thereon, and furthermore it includes power tracks (832), which form part of connecting means which are arranged for being connected to decoupling capacitors (21, 22) or which make up the connecting means (93, 94). The integrated circuit (1) can be a BGA-type integrated circuit, and the printed circuit board comprising components mounted thereon can be used advantageously in a single-chip cabel modem.
