12. Respecting Assembly Spacing and Rework Access Assembly, inspection, and rework depend heavily on having enough clearance between components and between components and the board edge. If parts are placed too closely, automated pick-and-place, soldering, optical inspection, and even manual repairs become difficult or impossible; leading to lower assembly yields, higher costs, and increased risk of solder bridging, tombstoning, or physical damage during rework. Crowded boards can also create thermal issues, complicate cleaning, and make probing or troubleshooting nearly impossible. When And Where To Apply Apply spacing and rework access rules as you place all components; not just during initial placement, but during every move, block shuffle, or layout revision. These checks are especially critical for boards with high component density, fine-pitch devices, or hand-assembly requirements. Pick and Place machine in action - the automated system that takes components from reels or trays and positions them with high precision onto solder pads on a PCB
