The shape should be as close to a square as possible. It is recommended to use 2 × 2, 3 × 3,…;
The width of the PCB circuit board is less than or equal to 260mm (SIEMENS line) or less than or equal to 300mm (FUJI line); if automatic dispensing is required, the width of the PCB puzzle × length ≤ 125 mm × 180 mm
The center distance between the small plates is controlled between 75 mm and 145 mm;
The outer frame (clamping edge) of the PCB circuit board should be closed-loop design to ensure that the PCB puzzle will not be deformed after being fixed on the fixture;
Four positioning holes are opened at the four corners of the outer frame of the PCB circuit board. The hole diameter is 4mm ± 0.01mm. The strength of the hole must be moderate to ensure that it will not break during the upper and lower boards. No burrs
There should be no large devices or protruding devices near the connection points between the outer frame and the inner small board, and between the small board and the small board, and there should be more than 0.5mm of space between the components and the edge of the PCB circuit board. Ensure that the cutting tool operates normally.
