A printed circuit board (PCB) may include a signal layer having a functional region and a PCB signal layer testing region. The PCB signal layer testing region may include a first differential pair having a first length formed on the signal layer, a second differential pair having a second length, different than the first length, formed on the signal layer and a third differential pair having a third length, different than the first length and different than the second length, formed on the signal layer.

A touch sensor and an electronic device are provided, and the touch sensor includes a film substrate and a plurality of touch electrode regions on the film substrate. The plurality of touch electrode regions are spaced apart from each other by at least one gap region, and the touch sensor is bendable along the gap region. The touch sensor is bendable and is not easily damaged, which helps to achieve foldable touch control.

A rigid-flex PCB includes an array of rigid PCB “islands” interconnected by a flexible PCB formed into flexible connectors. The conductive and insulating layers of the flexible PCB extend into the rigid PCBs, giving the electrical connections to the rigid PCBs added resistance to breakage as the rigid-flex PCB is repeatedly stressed by bending and twisting forces. In addition, the durability of the rigid-flex PCB is enhanced by making the power and signal lines driving the rigid PCBs redundant so that a breakage of a line will not necessarily affect the operation of the rigid PCB to which it is attached. The rigid-flex PCB is particularly applicable to light pads used in phototherapy, wherein LEDs mounted on the rigid-PCBs are powered and controlled through the redundant lines in the flexible PCB.

A sensor substrate includes a multi-layered substrate and a plurality of coils formed on the substrate, an upper-side coil includes a first sub coil including a plurality of conductor patterns connected in series with each other in the substrate, and a second sub coil including a plurality of conductor patterns connected in series with each other in the substrate, and in any of the even number of layers, the conductor pattern belonging to the first sub coil and the conductor pattern belonging to the second sub coil are aligned alternately in a planar direction, and one end of the first sub coil is connected to one terminal of a short land, while one end of the second sub coil is connected to the other terminal of the short land separated from the one terminal in the planar direction.

An electrical interconnection system for electrical components of a module includes a hub printed circuit board (PCB) having a first electrically conductive track and a second electrically conductive track. Each of the first and second electrically conductive tracks is configured to electrically connect at least two of the electrical components of the module, wherein the at least two of the electrical components of the module are external to the hub PCB. The system also includes multiple electrical terminals, wherein each of the electrical terminals is configured to electrically connect one of the first and second electrically conductive tracks of the hub PCB to one of the at least two electrical components of the module.

A conductive signal transmission structure for an electronic device (e.g., a printed circuit board of an electronic device) includes a copper material and a graphene layer disposed within the copper material at a depth below a surface of the structure.

A paddle card includes a printed circuit board and a twin-axial cable. The PCB includes a first signal pad on a top surface of the PCB and a second signal pad on a bottom surface of the PCB. The second signal pad is directly below the first signal pad. The twin-axial cable includes a first signal conductor coupled to the first signal pad and a second signal conductor coupled to the second signal pad.

A stretchable wiring board that includes a stretchable substrate having a first main surface with a first region, a second region adjacent the first region, and a third region adjacent the second region; a first stretchable wiring line on the first main surface and extending over the first region; an insulating layer extending over the first region and the second region; and a second stretchable wiring line extending over the first region, the second region, and the third region. When a thickness of the insulating layer is defined as Z2, and when a minimum value of a length of the second region in an extending direction of the second stretchable wiring line in a plan view of the stretchable wiring board is defined as Y, Y>Z2.

A system for preventing crosstalk between adjacent channels comprises a crossover connector positioned along a length of one channel such that a portion of a positive trace for a first channel is positioned adjacent to a positive trace of a positive trace of an adjacent channel. The position of the crossover connector is based on preventing crosstalk and crossover connectors on adjacent channels may be staggered to further prevent crosstalk. A crossover connector may be based on capacitors or resistors to prevent crosstalk.
