1. Introduction: Cutting Challenges in Small-Batch Production
Hardware startups face small-volume, multi-variety PCB depaneling needs. Traditional manual/V-CUT methods cause three critical pain points:
- Stress damage: Hand-breaking generates >500μm stress (IPC-A-610 verified), causing 40% micro-cracks
- Dust contamination: Cutting debris reduces BGA reliability, lowering yields by 15-20%
- Efficiency bottlenecks: Complex boards require 30min/panel, delaying product cycles
PCB router machines (also called PCB depaneling machines) provide the critical solution: ±0.02mm optical positioning, sealed dust extraction, and irregular board compatibility.
2. Core Selection Criteria for PCB Depaneling Machines
▎ Cutting Accuracy
- Safety threshold: ≤±0.05mm (prevents 0402 component damage)
- Seprays solution: GAM300 series with 12MP CCD achieves ±0.01mm repeatability
▎ Spindle Performance
- Speed range: 60,000-100,000 RPM (ceramic bearing life ≥3,000 hrs)
- Essential feature: ESD protection (<0.1kV discharge)
▎ Application Matching Guide
| Board Type | Recommended Machine | Seprays Model |
|---|---|---|
| Irregular/Multi-hole boards | Vision-based curve cutter | GAM320A |
| Small rectangular boards | Guillotine cutter | HK-200 (40% cost reduction) |
| Flexible PCBs/FPCs | Dual-platform system | GAM336AT |
▎ Automation Level
- Offline (Seprays GAM300): 0.8m² footprint, <5min changeover (ideal for <10 board types)
- Inline (GAM336AT): SMT line integration, 450 UPH output
3. Cost-Efficiency Evaluation Framework
| Cost Factor | Traditional Solutions | Seprays Router System |
|---|---|---|
| Equipment investment | $8,000-$15,000 | $6,200+ (HK-300 series) |
| Monthly tooling cost | $150 | $80 (60% longer tungsten tool life) |
| Hidden costs | 3-5% scrap rate | <0.1% (patented stress control) |
Efficiency benchmarks: ≥100mm/s cutting speed, ≤10min changeover (Quick-Change Fixture System)
4. Startup Selection Strategy
- Lightweight entry: HK-300 benchtop ($6,200, 0.6m² footprint)

6. FAQ: Critical Concerns Addressed
How does depaneling stress affect PCBs?
Stress >300μm cracks ceramic capacitors. Seprays machines reduce stress to <50μm (just 1% of manual breaking) via dynamic torque control.
Do startups need inline depaneling machines?
For monthly volume <5,000 panels, choose offline models (GAM300). Seprays provides modular upgrades to inline systems later.
