Important Considerations for PCB Assembly

• Ensure the outer frame of the PCB assembled board is designed in a closed-loop to prevent deformation.
• PCB panel width should be ≤260mm (SIEMENS line) or ≤300mm (FUJI line).
• Try to maintain a square shape for the PCB board, preferably in a 2×2 or 3×3 configuration.
• Control the center distance between small plates between 75 mm and 145 mm.
• Leave a non-resistance area of 1.5 mm around the reference positioning point.
• Avoid large or protruding devices near connection points on the PCB board.
• Include four positioning holes in the outer frame of the assembled board panel.
• Each small board must have at least three positioning holes.
• Use reference symbols for positioning the entire PCB and fine-pitch devices.
• Large components should have positioning posts or holes.
