摘要： A method for laying out a circuit board includes following steps. A substrate board is formed with a plurality of board sides. A ground plane, including a plurality of tiles, is provided. Each ground trace tile is defined by a plurality of ground traces. A signal plane on the substrate board has a plurality of signal traces that comprise of a plurality of straight line segments. Any one ground trace of each tile is arranged at an angle other than zero degrees relative to one determined board side. The straight line segments is applied to be mapped on the ground plane crossing one ground trace of one tile within an angle range determined by the ground traces of the tile and an adjacent diagonal line of the tile. The one ground trace and the straight line segments are applied at an angle movable in a range from 22.5° to 32.5°.

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： 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 circuit board assembly includes a circuit board and a semiconductor chip mounted on the board. The semiconductor chip includes a plurality of solder spots arrayed thereon in a matrix pattern. The solder spots except those located at corners of the pattern are jointed to the board via tin balls to form signal transmitting channels for transmitting signals between the board and the chip. Should the circuit board suffer impact, damage to the signal transmitting channels may be effectively minimized or prevented.
