Lasers for micromachining
The use of extremely short nano- and pico- and even femtosecond pulse durations helps to minimize the thermal effects such as melting and burr formation thus eliminating the need for any post processing measures. Every spot is creating indentiation in scale of um. Networ is not creating only flat but in practise 2.5D structure, changing of focus cause formation of 3D structure. High power density allows to use also lasers with shorter wavelength (335 nm or 532 nm), which is better absorbed in material and allows to use less power.
Surface roughness after the laser micromachining may range up to about 0.3 Ra values, so for most products is no need finishing operations.
Advantage of laser micromachining:
- Easy integration
- Non-contact and fast process
- High accuracy of repeated process
- No need of strong power sources due to shorter wavelengths
- 3D micromachining
- Formation of exact network of spot with low heat affected zone
- Quick investment return
