The thin connection line is connected between the two RJ45 connectors and the thin connection line includes a first flexible printed circuit board layer, a second flexible printed circuit board layer, and a spacing layer. The first flexible printed circuit board layer is provided with two first transmission lines respectively electrically connected to the third terminal and the sixth terminal. The second flexible printed circuit board layer is provided with two second transmission lines respectively electrically connected to the fourth terminal and the fifth terminal.

A lighting memory device and a memory module are provided. A lighting control circuit receives at least one lighting mode selection signal through lighting mode control pins and controls luminous characteristics of a plurality of light sources according to a lighting control mode corresponding to the lighting mode selection signal.

Methods for mounting a power amplifier (PA) assembly having an extended heat slug (11) are disclosed. According to one aspect, a method includes manufacturing a left side PCB (22a) and a right side PCB (22b). The method further includes sliding the left side PCB and the right side PCB inward (30) to encompass the PA assembly so that one of the left and right side PCB is in a position to contact a drain of the PA (13) and so that the other of the left and right side PCB is in a position to contact a gate of the PA (14).

A PCB mountable sensor having spring electrical contacts and mechanical attachment means is provided. In use, the spring contacts mate with exposed pads on a target PCB to form an electrical interface therebetween. The attachment means releasably secures the sensor to the PCB against the force of the spring contacts. The attachment means can be, for example, an adapter that fits like a collar around the sensor, or can be integral with the sensor. The design of the sensor provides interchangeability with no or limited tools, no PCB resident connectors, and no potential damage to the PCB upon rework or replacement.

A power distribution bus bar is provided for distributing power to surface mount connectors. In use, the power distribution bus bar includes a circuit board and at least two add-in card connectors each mounted to a first surface of the circuit board. Additionally, at least one power supply connector distributing a power supply to the add-in card connectors is provided. The at least one power supply connector may be mounted to a second surface of the circuit board and connected to the at least two add-in card connectors.

A fob key for a vehicle. The fob key for a vehicle includes a housing accommodating a printed circuit board mounted with touch switches and electrical parts, buttons arranged on the housing and able to move toward touch switches, and a button-supporting structure elastically supporting buttons in a direction far away from touch switches.

A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a .[.board mounted.]. connector of an electronic device to a chip on the device board. The bypass cable assembly has a structure that permits it, where it is terminated to the .[.board mounted.]. connector and the chip member, or closely proximate thereto.[.. to replicate closely the geometry of the cable. The connector terminals are arranged in alignment with the cable signal conductors and shield extensions are provided so that shielding can be provided up to and over the termination between the cable signal conductors and the board connector terminal tails. Likewise, a similar termination structure is provided at the opposite end of the cable where a pair of terminals are supported by a second connector body and enclosed in a shield collar. The shield collar has an extension that engages the second end of the cable.]..Iadd., to allow signals to be transmitted at greater than 10 GHz with substantially lower loss than a traditional FR4 circuit board. .Iaddend.

A board element for board-to-board interconnect formation is provided. An embodiment includes embedding a signal via element in the board element and cutting through respective sections of the board element and the signal via element to expose a new board element edge and an outwardly facing surface of the signal via element.

An optical subassembly and an optical module are provided. The optical subassembly includes an optical transmitter, an optical receiver, an optical splitter, and an optical fiber stub. The optical transmitter is configured to transmit light from the optical transmitter to the optical fiber stub through the optical splitter. The optical splitter is configured to reflect light from the optical fiber stub to the optical receiver. An optical axis of the optical receiver and an optical axis of the optical fiber stub form an acute angle. An optical axis of the optical transmitter and the optical axis of the optical fiber stub also form an acute angle.

The present invention has advantages in that as a USB port unit and a hard disk port unit are formed on the edge of the substrate unit thereby allowing external USB and external disks to be directly connected to the main board, so that it prevents electrical malfunction caused by cable connection, and as the transmission speed of high-speed communication increases through direct connection, it is to provide a main board for POS terminal which may maintain stable system by reducing communication errors.
