There are various ways to split PCB boards, and the following will introduce several common ways of splitting:

　　1. Milling and cutting of PCB boards: Using a CNC milling machine, cut grooves on the PCB board and use a rotating tool or milling cutter to cut the board into small pieces, suitable for various shapes and sizes of boards.

　　2. Punching and Splitting: Through die-cutting technology, holes are pressed on the PCB board, and then force is applied to break the board, achieving the splitting operation, suitable for rectangular and regular shaped boards.

　　3. V-knife board splitting: Use a special V-shaped blade to cut V-shaped slots on the PCB board, then apply force to break the board and separate it into small pieces, suitable for thinner boards and situations with high precision requirements.

　　4. Laser board splitting: Using laser cutting technology, precise cutting can be performed on PCB boards to achieve complex shapes and high-precision board splitting requirements, suitable for high-end products and complex designs.

　　5. Mechanical cutting: Using a band saw or blade mechanical equipment to perform straight or curved cutting on a PCB board, dividing the board into small pieces as needed, suitable for general shapes and sizes of boards.
