What is the working principle of router paneling?
Router depaneling is a precision PCB separation process that utilizes computer-controlled spindle systems equipped with specialized cutting tools to simulate individual boards from production panels. The CNC-guided operation follows pre-programmed toolpaths to achieve micron-level cutting accuracy while maintaining high throughput rates. This mechanical method offers distinct advantages for thicker multilayer boards and complex designs, combining the reliability of traditional milling with advanced features like real-time tool monitoring and automated debris management. The process eliminates the need for consumables associated with laser systems while delivering consistent results across high-volume production runs. Proper tool maintenance remains essential to preserve cut quality and prevent potential defects in sensitive board areas.
What are the advantages of Router handling compared to traditional punch depaneling?
| Feature | Router Depaneling | Punch Depaneling |
| Precision | ±25μm (micron-level) | ±100–200μm (limited by die tolerance) |
| Stress on PCB | Low (controlled cutting force) | High (impact force risks delamination) |
| Tooling Cost | No custom dies (uses standard end mills) | High (5k–5k–20k per die design) |
| Setup Time | Minutes (digital toolpath upload) | Hours (die alignment/calibration) |
| Design Flexibility | Unlimited (CAD-driven, handles complex shapes) | Limited (fixed die geometry) |
| Material Compatibility | FR4, Rogers, metal-core, rigid-flex (0.1–6mm) | Best for simple FR4 designs (≤3mm) |
| Edge Quality | Burr-free (meets IPC-A-600 Class 3) | May require deburring |
| Throughput | 300–800 panels/hour | 1,000+ panels/hour (for simple designs) |
| Automation | Fully automatable (vision/ATC integration) | Limited by manual die changes |
| Best For | High-mix, complex, or sensitive PCBs | High-volume, simple designs |
