Circuit board cutting is the process of dividing a circuit board into smaller pieces while maintaining its functionality. It is typically performed using a PCB cutting machine and various cutting methods such as milling, scoring, or laser cutting. Proper PCB cutting is crucial for ensuring the overall functionality and performance of the circuit board, and it is important to follow proper guidelines and techniques to avoid damaging the board and its components. V-cutting is a common cutting method that creates dividing lines on the PCB for subsequent assembly. Stamp holes may be used to connect irregular or circular boards and to create independent PCB modules. Overall, PCB cutting is an essential process in the manufacturing and assembly of circuit boards to create pieces that fit specific design requirements and dimensions and improve efficiency and reduce costs in mass production.
