company news about Engineering specification for fully automatic splitter

PCB engineering specification of automatic board splitter:

1. The appearance width of the printed circuit board is 260mm or less (Siemens) or 300mm or less (Fuji); if you need automatic dispensing, the width x length of the PCB patch is 125mm*180mm or less.

2. It is recommended not to inlay the yin and yang board.

3. The circuit board puzzle frame (clamping side) adopts a closed-loop design to ensure that the PCB on the fixture will not be deformed after it is buckled.

4. The distance between the centers of the small plates is controlled between 75 mm and 145 mm.

5. There should be no large equipment or components near the connection point between the rack and the internal small board, and the spacing between edge PCBs and components should be greater than 0.5mm. A fully automatic splitter is a tool to ensure the normal operation of the equipment.

6. There are four corner positioning holes outside the labyrinth box, with a diameter of 4mm+/-0.01mm; the strength of the holes is moderate to ensure that they will not be reduced during the fracture process; the size and position are accurate, and the whole wall is smooth and free of burrs.

7. The circuit board puzzle should have at least three positioning holes on each small circuit board, 3 holes 6mm or less, or side positioning holes less than 1mm. Wiring or wiring is not allowed.

8. The circuit board of the automatic board divider positioning board is used as the reference symbol of the micro device. In principle, set the QFP with a spacing of less than 0.65mm in the diagonal position; the positioning reference of the circuit board puzzle should use paired symbols to decorate the diagonal positioning elements. When setting the reference anchor point, the welding area at the anchor point is usually greater than 1.5mm.
