Laser Drilled Ceramic Substrates
Laser drilled holes in substrates of Aluminum Nitride and Aluminum Oxide have slag which occurs when the substrate material is melted by the laser beam.
Techniques used for slag removal are:
- Abrasive Blasting
- Abrasive Vibratory
- Chemical Etching
- Combination of several mentioned above
We have experience with all techniques mentioned and have developed new processes which eliminate damage to the substrate surface with special emphases to laser drilled holes and slots in Aluminum Nitride substrates.
