PCB V-score, also known as V-cut or V-groove, is a depanelization method that uses angled blades to cut V-shaped grooves on both sides of a PCB panel.

This process leaves a thin remaining web that allows individual boards to be easily separated after assembly. It is a popular choice for high-volume PCB manufacturing.

Why PCB V-Score Guidelines Are Important？

Following proper pcb v-score guidelines is critical to ensure:

• Clean and controlled depanelization

• Prevention of board cracking or edge damage

• Protection of copper traces and solder joints

• Consistent quality during high-volume production

Improper V-score design can lead to mechanical stress, copper exposure, or assembly defects.

When Is PCB V-Score Commonly Used?

PCB V-score is best suited for:

• Large quantity production

• Straight-edged PCB designs

• Automated SMT assembly processes

• Cost-focused projects

For complex shapes, routing is usually recommended.

Key Design Points to Consider

Good PCB V-score design includes:

• Matching V-score depth to board  thickness

• Keeping copper and components away from V-score lines

• Using symmetrical V-cuts on both sides  of the board

These considerations reduce stress during separation.

How PCBBUY Supports PCB V-Score？

PCBBUY helps customers achieve reliable V-score results by:

• Reviewing designs for V-score feasibility

• Controlling V-score depth and consistency

• Offering alternative depanelization methods when needed

This approach helps avoid costly production issues.

When Should You Avoid V-Score?

You should consider routing instead of V-score if your PCB has:

• Irregular outlines

• Copper or components near the board edge

• High mechanical strength requirements

PCBBUY engineers can help recommend the best solution.

FAQ

What is PCB V-score?

PCB V-score is a depanelization method that uses V-shaped grooves to allow easy separation of boards from a panel.

When should I use PCB V-score instead of routing?

V-score is best for straight-edge, rectangular boards produced in high volumes.

How deep should a PCB V-score be?

V-score depth depends on board thickness and must leave sufficient material for handling while allowing easy separation.

How close can copper be to a V-score?

Copper features should maintain a safe distance from the V-score line to avoid cracking or exposure after depanelization.

Can PCBBUY support PCB V-score processing?

Yes. PCBBUY provides PCB V-score processing with DFM review and controlled manufacturing processes.
