Everything You Need to Know About PCB V-Scoring!

Printed Circuit Board (PCB) manufacturing involves numerous precision techniques, and V-scoring is one of the most critical methods for separating individual boards from a larger panel. This specialized process plays a crucial role in modern electronics manufacturing, offering an efficient and precise way to separate PCBs while maintaining the integrity of the board's components.

What is V-Scoring?

Basic Concept of V-Scoring

V-scoring is a PCB panel separation technique that involves creating a V-shaped groove along the surface of a printed circuit board panel. This groove allows for easy separation of individual boards during the final stages of the manufacturing process. RayMing PCB has been at the forefront of implementing advanced V-scoring techniques to enhance manufacturing efficiency.

Technical Mechanics of V-Scoring

The V-scoring process involves:

1. Precise cutting of a V-shaped groove
2. Partial depth cutting through the board
3. Leaving a small amount of material intact
4. Enabling clean and controlled board separation
