Ten things to pay attention to in PCB assembly: 1. Use a closed-loop design for the outer frame. 2. Control PCB panel width. 3. Prefer square board shape. 4. Control center distance between small plates. 5. Leave non-resistance area around reference positioning point. 6. Avoid large devices near connection points. 7. Make positioning holes in panel corners. 8. Ensure each small board has at least three positioning holes. 9. Use reference symbols for positioning. 10. Use positioning posts or holes for large components.
