[0002] When the incoming PCB board is 4*5=20 connected boards (i.e. 4 boards per row, 5 rows in total), and there are two ways to arrange the PCB boards, one is that each PCB board is arranged in an array with exactly the same direction, and the other is a mandarin duck board arrangement, that is, two PCB boards are arranged in rotational symmetry.
