Laser drilling
Laser drilling makes it possible to create through or blind holes with variable shape and high aspect ratio, on all types of materials and thicknesses.
The characteristics of laser drilling:
Benefits
- Diameter <10 μm
- Adaptable shape
- Aspect ratio >15
- Drilling transparent materials
- Cylindrical drilling
Performance
- Tolerances of a few μm
- Accuracy of a few μm
- Depth and geometry control
Throughput
- Dependant on material thickness
- From ms to s per hole
Laser workstation
- Pulse duration from fs to ms
- Trepanning head
- Drilling head
- Scanning systems
- Wavelength from IR to UV
Surface condition
Roughness of a few hundreds of nm on the hole inner surface
Process sheet
