    摘要: An exemplary optical disc drive apparatus includes a guide shaft configured to movably support a pickup head, and an elastically deformable member. The elastically deformable member includes a main body, and a cantilever slanting up from a middle part of a front edge of the main body. The cantilever is broad at a lower portion thereof and narrow at an upper portion thereof, and the cantilever is for resiliently pressing a corresponding end of the guide shaft. The elastically deformable member reduces a stress surface between the cantilever and the guide shaft, and lengthens the life span thereof.

    摘要: A motherboard includes a circuit board, a first chip and a second chip disposed on the circuit board. Four securing holes are defined in the circuit board around the first chip, for mounting a heat dissipating module on the first chip. Two of the securing holes determine a first line, and the other two securing holes determine a second line parallel to the first line. A center of the second chip is located along a centerline between the first and second lines. Should the circuit board suffer from an impact, damage to the chips may be effectively minimized or prevented.

    摘要: A multi-layer printed circuit board (PCB) is provided allowing balanced power supply to components requiring large working current. The PCB includes a plurality of layers disposed thereon. A first power area, and a second power area are separately arranged on different layers. The first power area and the second power area vertically aligned within the PCB with generally identical shapes cooperatively provide power to components requiring large working current.

    摘要: A printed circuit board (PCB) with crosstalk reduction arrangement of differential vias includes a plurality of groups of differential vias, a plurality of signal lines corresponding to the differential vias, and a plurality of layers electrically connected with each other by the differential vias and signal lines. Each group of differential vias comprises a first pair of differential vias and a second pair of differential vias. Straight lines from a center of one of the first pair of vias to a center of another of the first pair of vias and from a center of one of the second pair of differential vias to a center of another of the second pair of differential vias are mutually perpendicularly bisecting.

    摘要: A signal transmitting circuit includes a driving circuit, and a plurality of receiving circuits receiving signals transmitted from the driving circuit. Each of the receiving circuits is coupled to the driving circuit consecutively via a transmission line. A voltage regulator is coupled to the driving circuit and the receiving circuits and provides power to the driving circuit and the receiving circuits. A number of capacitors are coupled between the voltage regulator and the ground for filtering the noise of the power output from the voltage regulator. The capacitors between the voltage regulator and the north bridge chipset filtering the noise of the power output from the voltage regulator maintain signal integrity as the terminal resistor does. It is of advantage that the signal transmitting circuit is simple to manufacture and very suitable for mass production.
