The mounter plays important role in PCB production. And its performance is affected by the job scheduling for PCB production. Automation of job scheduling is an important issue in PCB production automation. For each different types of machine, model for scheduling and algorithm which find a schedule for different PCB`s in the model is suggested. Recently, the mounter, which has simultaneous placement capability, is developed. And no existing model is appropriate for this type of mounters. In this thesis, model for such mounter, which considers simultaneous placement, would be suggested and job program generation algorithm for it would also be suggested. And lower bound analysis for production time and comparison with generated job program and lower bound would be done.
