    Abstract: A circuit structure includes a low-density conductive structure, a high-density conductive structure and a plurality of traces. The high-density conductive structure is disposed over the low-density conductive structure, and defines an opening extending from a top surface of the high-density conductive structure to a bottom surface of the high-density conductive structure. The opening exposes a first pad of the low-density conductive structure and a second pad of the low-density conductive structure. The second pad is spaced apart from the first pad. The traces extend from the top surface of the high-density conductive structure into the opening. The traces include a first trace connecting to the first pad of the low-density conductive structure and a second trace connecting to the second pad of the low-density conductive structure.

    Abstract: A printed circuit board includes first and second insulating layers, first and second strip line circuit traces formed on a surface of the first insulating layer, and a patterned dielectric material. The first strip line circuit trace has a first length and carries a first signal. The second strip line circuit trace is adjacent to the first strip line circuit trace, has a second length longer than the first length, and carries a second signal. The patterned dielectric material is provided over a portion of the first length to delay the first signal relative to the second signal. The second insulating layer is affixed to the surface and covers the first and second strip line circuit traces and the patterned dielectric material.

    Abstract: A terminal, in which terminal conductors are disposed, is preliminarily formed on one surface of a substrate. Electrode conductors including covered lead wires are disposed in a region on the one surface of the substrate that does not overlap the terminal, the electrode conductors being bonded to the substrate by an adhesive material to form a predetermined conductor pattern, whereby a sensor pattern is disposed on the substrate. The lead wires of the electrode conductors are exposed due to the covering being removed at ends of the covered lead wires, the exposed lead wires are disposed while being aligned with and connectable to the corresponding terminal conductors of the terminal. The terminal conductors of the terminal and respective exposed lead wires of the electrode conductors of the sensor pattern are then electrically connected.

    Abstract: The present disclosure relates to a PCB and a method in the PCB for reducing common-mode current. The PCB comprises two differential lines and each of the differential lines is on one or more planes of the PCB. The two differential lines carry a differential mode current and the common mode current. The differential mode current and the common mode current may be at least one of a forward current and a backward current. Further, a predefined configuration is formed using each of the two differential lines to generate impedance at the predefined configuration. Here, the predefined configuration is placed close to each other to generate a dielectric capacitance. The flow of the forward current and the backward current in adjacent tracks of each of the two differential lines in the predefined configuration are in opposite direction.
