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： The invention related to a method and circuit that is used to compensate for S-parameters of a passive circuit which do not satisfy passivity. The method includes the following steps: (1) getting S-parameters which do not satisfy passivity, these S-parameters being composed of an S-parameter matrix S; (2) computing matrix [S×S′], wherein matrix S′ is a complex conjugate transposed matrix of the S-parameter matrix S; (3) computing the eigenvalues of the matrix [S×S′], and choosing an eigenvalue Ψ whose real part real(Ψ) is the biggest; (4) computing a compensating value ξ, the compensating value ξ being equal to real(Ψ)1/2×(1+ε), wherein the ε is a very small positive number; and (5) dividing each of the S-parameters by the compensating value ξ to get the compensated S-parameters.
