Laser separation system machine of working principle
LLO operates through selective ablation at material interfaces:
Laser Irradiation: High-energy pulses (e.g., excimer or femtosecond lasers) focus on the target interface (e.g., sapphire-GaN), inducing photothermal/photochemical reactions.
Interface Decomposition: Laser energy triggers gasification (e.g., GaN → Ga + N₂), generating plasma and thermal stress for controlled delamination.
Material Collection: Delaminated microstructures are captured via vacuum suction or fluid dynamics, ensuring contamination-free transfer.
Key Technologies:
- Ultrafast Lasers: Femtosecond pulses (<100fs) minimize thermal damage (e.g., MicroLED separation).
- Beam Shaping: Linear/rectangular beam profiles enhance efficiency (e.g., flexible PCB batch processing).
