Laser scribing

1 mm thick AlN scribed and broken
Laser scribing initially involves introducing a 20 to 50 μm thick groove in the ceramic material. The material along this groove is then broken. Laser scribing makes it possible to cleanly separate segments with a high level of quality and accuracy.
Unlike mechanical processing, this method leaves no micro-fractures in the material. And because only a minor amount of material is ablated, very high scribing speeds of up to 100 mm/s are possible (depending on the material) without generating the micro-fractures typical of mechanical processing.
