jump v-scoring with selective PCB v-groove technique

Jump V-Scoring (Skip V-Groove PCB)

Jump V-scoring, also known as skip V-groove PCB, refers to a V-cut (V-scoring) process in PCB depaneling where the cutting tool skips certain areas and does not cut, only scoring where separation is needed while leaving other areas uncut.

Application Scenarios

1. Commonly used when certain areas on a single board must remain connected, or when special structures require retained connection strength in PCB design.
2. Typical applications: boards with connecting bridges, partial panelization, or electronic products with special structural requirements.

Advantages

1. Improves overall PCB strength and helps prevent accidental breakage during transport or assembly.
2. Flexibly meets different depaneling and connection requirements in specific areas.

Example

For instance, on a panelized board where most areas need to be separated except for a segment in the middle, jump V-scoring can be used—the V-cut tool will automatically lift and skip that region without cutting.
