3. Traditionally, research in this field can be categorized into:
4. Laser PCB processing systems, which include lasers, light guide systems, processing machine tools, control systems, and inspection systems.
2. **Laser PCB Processing Technology**: This includes cutting, welding, surface treatment, punching, marking, scribing, fine-tuning, and other processing techniques.
**Laser Welding**: Used for sealing devices such as automobile body plates (both thick and thin), automobile parts, lithium batteries, cardiac pacemakers, sealed relays, and various devices requiring non-polluting and non-deforming welding. Current lasers used include YAG, CO2, and semiconductor pump lasers.
**Laser Cutting**: Applied in the automotive industry, computers, electrical casings, wooden knife molds, metal parts, special materials, circular saw blades, acrylic, spring gaskets, copper plates (below 2mm), metal mesh panels, steel pipes, tin-plated iron plates, lead-plated steel plates, phosphor bronze, Bakelite, thin aluminum alloys, quartz glass, silicon rubber, alumina ceramic sheets (below 1mm), and titanium alloys for aerospace. The lasers used include YAG and CO2.
**Laser Marking**: Extensively used across various materials and industries. Lasers currently in use include YAG, CO2, and semiconductor pump lasers.
**Laser Drilling**: Primarily used in aerospace, automobile manufacturing, electronic instrumentation, and chemicals. The development of laser drilling is noted by the increase in average output power of YAG lasers from 400W to 800W-1000W over the past five years. In China, laser drilling is notably applied in producing synthetic and natural diamond wire drawing dies, jewel bearings for watches and instruments, aircraft blades, and multilayer PCBs. The lasers in use are mostly YAG and CO2, with some excimer, isotope, and semiconductor pump lasers.
**Laser Heat Treatment**: Widely applied in the automotive industry for cylinder liners, crankshafts, piston rings, commutators, gears, and other parts. It is also common in aerospace, machine tool industries, and other machinery sectors. Laser heat treatment in China is more prevalent compared to foreign countries. The lasers used are primarily YAG and CO2.
**Laser Rapid Prototyping**: This integrates laser PCB processing technology with computer numerical control and flexible manufacturing technologies, primarily used in mold and model industries. The lasers used are mainly YAG and CO2.
**Laser Coating**: Extensively used in aerospace, mold, and electromechanical industries. High-power YAG and CO2 lasers are the primary types in use.
