AI Overview
Laser drilling Aluminum Nitride (
) enables precise, high-speed micro-hole fabrication for electronics, typically using CO
, fiber, or Nd:YAG lasers. This non-contact process manages
's brittle nature, but it often produces thermal damage and slag (melted material) that require removal. Advanced techniques like water-spray assistance or controlled atmospheres improve quality.
