PCB routing and V-cut (also known as scoring) are two different methods used for separating printed circuit boards (PCBs) from a larger panel after the PCBs have been fabricated.
PCB routing involves using a mechanical cutting tool, such as a router or a milling machine, to create a groove or channel along the desired separation lines on the PCB panel. The router cuts through the copper traces, dielectric material, and other layers of the PCB, creating separate PCBs with clean edges.
V-cut, on the other hand, involves creating a V-shaped groove or scoreline on the top side of the PCB panel using a special cutting tool or blade. The depth of the groove is typically controlled to reach a certain depth without cutting through the entire panel. Once the scoreline is created, the panel can be flexed or bent along the groove, causing the PCBs to separate along the groove lines.
Both PCB routing and V-cut have their advantages and disadvantages, and the choice between the two methods depends on the specific requirements of the PCB fabrication process, the desired edge quality, flexibility, and cost considerations. PCB manufacturers typically choose the most appropriate method based on their production capabilities, equipment, and design requirements.
