1. The shape of the PCB panel should be as close to a square as possible. It is recommended to use 2×2, 3×3,...

    2. The outer frame (clamping edge) of the PCB panel should adopt a closed-loop design to ensure that the PCB panel will not be deformed after it is fixed on the fixture;

    3. The center distance between the small plates is controlled between 75 mm and 145 mm;

    4. PCB panel width ≤ 260mm (SIEMENS line) or ≤ 300mm (FUJI line); if automatic dispensing is required, PCB panel width × length ≤ 125 mm × 180 mm;

    5. There should be no large components or protruding components near the connection point between the outer frame of the puzzle and the inner small board, and between the small board and the small board, and there should be a space greater than 0.5mm between the components and the edge of the PCB board. To ensure the normal operation of the cutting tool;

    6. When setting the reference point, usually leave a 1.5 mm larger than non-soldering area around the point;

    8. Each small board in the PCB panel must have at least three holes, 3≤aperture≤6mm, and no wiring or patch is allowed within 1mm of the edge hole;

    9. Open four holes in the four corners of the outer frame of the jigsaw, with a diameter of 4mm ± 0.01mm; the strength of the holes should be moderate to ensure that the plate will not be broken during the process of upper and lower plates; the hole diameter and position accuracy should be high, and the hole wall should be smooth and free of burrs;

    10. For the whole board of PCB and the reference symbols for fine-pitch devices, in principle, QFPs with a spacing of less than 0.65mm should be set at their diagonal positions; the reference symbols for imposition PCB daughter boards should be used in pairs and arranged. at the opposite corner of the element;

    11. Large components should have columns or holes, such as I/O interfaces, microphones, battery interfaces, micro switches, headphone interfaces, motors, etc.;
