Power lines to short line width to be as wide as possible;

Line should avoid acute angles, right angles. With 135 ° line;

Usually minimum line width requirements for 4mil, minimum space requirements for 4.5mil;

High frequency signals as short as possible, line VIA as little as possible, do not allow cross-cutting surface;

Distance between two points is small (such as SMD devices adjacent pads), directly connected to the solder shall not be;

Whole piece of circuit board wiring, holes should be uniform to avoid obvious cases of uneven density. When the outer layers of the PCB signal when there is a large blank areas, and guides the Board balance wire distribution;

Input and output signals to avoid adjacent parallel wires plus ground wire between the best online to prevent feedback coupling;
