摘要

Surface Mount Technology (SMT) is a robust methodology that has been widely used in the past decade to produce circuit boards. Analyses have shown that the automated placement stage is often the bottleneck among all the stages in the SMT production line. Improving the performance of this stage is a key issue for increasing SMT production line throughput. This paper presents experimental results using genetic algorithms to optimize gantry-type SMT placement machines. Four crossover operators, four selection methods, and several probability settings are used in our experiments. A penalty function is used to handle constraints. Comparison of genetic algorithms with local search is presented in support of the use of genetic algorithms for this problem.
