Laser Drilling
Laser drilling produces holes by percussion or trepanning, from tens of microns upward. Optics and pulse parameters set diameter and taper, not a bit. It suits vents in device housings, vias in flexible circuits, filters, and metered-flow features in medical disposables.
How it works
Percussion drilling stacks pulses at one point until breakthrough. Trepanning traces the hole outline with a focused spot, for larger or tighter-tolerance holes. The material and the heat-affected zone the application tolerates decide the source, NIR or UV. They also decide the pulse duration, nanosecond through femtosecond. The two choices are independent.

Process envelope
| Hole diameter | From ~20 µmMaterial- and thickness-dependent; trial data required. |
|---|---|
| Method | Percussion or trepanning |
| Sources | NIR, UV; nanosecond to femtosecond |
| Heat-affected zone | Minimal with ultrashort pulses |
Drilling is where burr matters most. A mechanical hole in thin metal carries a burr on the exit side, and in a fastener, a filter, or a fluidic channel that burr is a defect. A laser hole carries no mechanical exit burr. We measure exit-edge condition, taper, and recast on your holes and report them.
