Every depaneling method introduces some board stress. The question is how much, and whether it reaches sensitive components. V-cut scoring is fast but concentrates stress at the score line; routing isolates stress to the mill path.
| Method | Stress | Precision | Speed | Best for |
|---|---|---|---|---|
| Router mill | Low (localized) | ±0.02mm | Medium | Dense / sensitive boards |
| V-cut | Higher at score | Good | High | Simple panels, high volume |
| Punch | Impact | Fixed tool | Very high | Identical high-volume parts |
Router milling localizes stress to the cut path and is safest for boards with components near the separation edge.
Yes, V-cut and punch methods are faster for uniform panels; routing trades some speed for lower stress and flexibility.
Router separators with quick-change fixtures and custom jigs handle mixed products, which suits contract manufacturers with frequent changeovers.
