Laser drilling


Accurate hole drilling (random or step and repeat).

Minimum hole diameter:
pulsing 0.1 mm
drilling 0.25 mm

Tolerances for cost effective manufacture are:

  1. hole diameter +/- 0.05 mm
  2. hole tapers ~ 5% of substrate thickness
  3. hole centre to hole centre +/- 0.05 mm
  4. wall thickness between adjacent holes >/= substrate thickness
  5. wall thickess between hole edge and another edge >/= substrates thickness
  6. scribed edge to hole centre +0.15/-0.05 mm
  7. profiles edge to hole centre +/- 0.05 mm
  8. centre of scribed line to hole centre +/- 0.05 mm
