ABSTRACT:
A method for designing stacked pattern of PCB utilizing genetic algorithm and the system thereof are disclosed. The method comprises the following steps: First of all, information data of stacked pattern is inputted into operational interface of the software; Next, initial solution sets of stacked pattern are generated; Then, duplications of the initial solution sets of stacked pattern are generated according to a fitness function; Afterward, crossover of the duplications of stacked pattern are performed at random; Then, mutations are executed by a probability at random; Finally, identification is performed to check if the solution approaches the standard of demand and the result of stacked pattern is shown; otherwise, operational step jumps to duplicate step and repeats above steps until satisfying solution is obtained. The most suitable way for package can be arranged out through making especially mathematical calculations by the system efficiently.
