Layout Optimization for Mass Production of PCB Boards in SMT Assembly

SMT (Surface Mount Technology) placement is a core backend process in PCB batch production. The efficiency and yield of an automated SMT line heavily depend on the preliminary PCB layout design. In the batch projects I've encountered, nearly 30% of SMT defects can be traced back to PCB layout issues
