    Abstract: A hybrid electromagnetic bandgap (EBG) structure for broadband suppression of noise on printed wiring boards includes an array of coplanar patches interconnected into a grid by series inductances, and a corresponding array of shunt LC networks connecting the coplanar patches to a second conductive plane. This combination of series inductances and shunt resonant vias lowers the cutoff frequency for the fundamental stopband. The series inductances and shunt capacitances may be implemented using surface mount component technology, or printed traces. Patches may also be interconnected by coplanar coupled transmission lines. The even and odd mode impedances of the coupled lines may be increased by forming slots in the second conductive plane disposed opposite to the transmission line, lowering the cutoff frequency and increasing the bandwidth of the fundamental stopband. Coplanar EBG structures may be integrated into power distribution networks of printed wiring boards for broadband suppression of electromagnetic noise.

    Abstract: A printed circuit board includes a signal layer, an insulation layer, and a reference layer. A transmission line is located on the signal layer. A probing pad is located on the transmission line. Two aligned slots defined in opposite sides of the reference layer leaving a connecting portion. The slots and the connecting portion are in vertical alignment with the probing pad. The signal layer, the insulation layer, and the reference layer are configured in a cascading order. An arrangement of the signal layer in relation to the reference layer including the slots and the connecting portion reduces a capacitance effect caused by the probing pad.

    Abstract: A dual footprint mounting package for a surface mount power converter modules and its method of manufacture. Castellated regions are formed on the edge of the component package using the appropriate sized drill or milling bit. Edge plating is applied to the castellated surfaces to create edge pads. The edge plating provides electrical continuity between the edge pads and the SMT pads. Solder mask, or other materials, is applied to prevent solder from wicking between each SMT pad and its respective edge pad. Such component may be attached to a larger device PWB using either the edge pads or the SMT pads, or may even be attached using a combination of the two, such as in the event of a pad failure or other defect.
