Abstract:
A multilayer substrate that retains a curved state without causing fluctuations in electrical characteristics includes a main body including a plurality of insulating sheets to be stacked and made of a flexible material. A signal wire extends in the main body. A ground conductor is provided at a positive-direction side in a z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. A ground conductor is provided on a negative-direction side in the z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. The state in which the main body is curved so that the signal wire defines an arc is retained by plastic deformation of the ground conductors.
Abstract:
An electrical connector comprises a PCB (220) having a front edge to be inserted into a mating receptacle. The PCB comprises a top face having a row of first mating pads (242), and an opposite bottom face having a row of second mating pads (262) and a row of third mating pads (264) behind the second row of mating pads. The first and second mating pads are compatibly fit with an SFP receptacle (120). The PCB comprises a first sub-PCB (540) having a first outer layer containing the first mating pads and an opposite second outer layer containing the second mating pads, and a second sub-PCB (560) attached to the second outer layer on an area behind the second mating pads, the second sub-PCB having a second outer layer containing the third mating pads.
Abstract:
A computer motherboard includes a printed circuit board which includes a central processing unit (CPU) socket and a group of memory slots. The group of memory slots includes an in-line type memory slot and a surface mounted device (SMD) type memory slot. The in-line type memory slot includes a number of plated through holes. The SMD type memory slot is set between the in-line type memory slot and the CPU socket. The through holes of the in-line type memory slot are connected to the CPU socket through traces, pads of the SMD type memory slot are connected to corresponding through holes of the in-line type memory slot having the same pin definition.
