The Evolution of PCB Depaneling: From Manual to Automated Solutions

As manual PCB separation causes board damage and low efficiency, automated solutions dominate modern SMT lines. Seven primary depaneling machines exist, with laser cutters and PCB router machines being industry focal points.

◼ Laser Depaneling Systems

• Laser Options: UV (for ≤1mm boards), Green (＞1mm), CO₂, Picosecond

• Advantages:
  ✓ Non-contact cutting eliminates stress
  ✓ Burr/carbonization-free edges
  ✓ Integrated dust extraction
  ✓ Automated CCD positioning

• Limitation: High initial investment

◼ PCB Router Machine (Milling Type)

• Operation: Physical routing with high-speed spindles

• Advantages:
  ✓ Lower equipment cost
  ✓ Ideal for SMEs/small-batch production

• Drawbacks:
  ✗ Mechanical stress risks board damage
  ✗ Requires post-processing for edge smoothness
  ✗ Demands external dust control

Pro Tip: For cost-driven projects under 5,000 units/month, modern PCB router machines with ceramic-coated blades reduce debris by 78% while maintaining 25% lower TCO than laser alternatives.
