1.拼板尺寸，重量过大可能会导致变形；2.V-CUT和邮票孔连接不满足

1. If the size of the <br>panel is too large, it may cause deformation; 2. The connection between the V-CUT and the stamp hole does not meet the mechanical strength; <br>3. The manual splitting of the board causes the force and deformation of the PCB V-CUT, resulting in damage to the PCB or components;

1. Splint size, too much weight may cause deformation;<br>2.V-CUT and stamp hole connections do not meet mechanical strength;<br>3. Artificial sub-board causes force deformation at PCB V-CUT, resulting in PCB or component damage;
