Abstract: It is the problem that weak immunity of Printed Circuit Board(PCB) resulted by the low thermal dissipation performance with unreasonable layout and the low noise immunity performance without optimization wiring. To attack the problem, an algorithm based on collaboration between the layout and the wiring is proposed. The algorithm adopts the rule based on Cellular Automata(CA) transfers the position of components according to temperature limitation for layout so that the heat dissipation performance of layout can be more reasonable and the method is proposed based on Ant Colony Algorithm(ACA) looks for the shortest routing length and the minimum number of holes and evaluates PCB noise immunity performance for wiring. Experimental result shows that performance of heat dissipation is increased by 14% on the aspect of heat dissipation for the layout, the average routing length and number of holes are decreased obviously on the aspect of noise immunity for the wiring and the PCB total average temperature is decreased by 14%.
