Laser Micro Drilling

Glass drilling     Sapphire drilling     Ceramics drilling     Optical fibers drilling     Metal drilling

Laser micro drilling ensures high drilling speed, good surface quality and a wide range of hole diameters. The holes are drilled with a controlled taper in various materials – even hard and fragile.

Features

  • Taper control
  • Good bottom and sidewall quality of drilled wells
  • Variable geometry of holes
  • High speed laser processing
  • No melting and micro-cracks in peripheries
  • Broad range of available parameters to suit every material
  • Smooth drilled hole side wall and bottom finish

Glass drilling

Laser drilling of glass using femtosecond laser radiation is a state of the art technique showing many advantages over conventional laser processing, mechanical drilling, or lithography. We use conventional laser drilling techniques, as well as unique Workshop of Photonics developed methods to achieve the highest quality in the market.

Advantages – lower costs, minimal surface finish needed, and ultra-high accuracy.

Features:

  • No melting and micro-cracks in peripheries
  • Aspect ratio up to 1:100
  • Possibility for very densely packed hole arrays
  • Zero taper

Different processing parameters might be developed upon request.

Sapphire drilling

Laser drilling of sapphire using femtosecond laser radiation is a unique processing technique enabling no cracks in hole peripheries, accurate taper control, and smooth wall finish. Workshop of Photonics continues the development of sapphire drilling techniques to meet our customers’ needs.

Advantages –ultra-high accuracy, reliable process control, minimal or no post-processing is needed.

Features:

  • No melting and micro-cracks in peripheries
  • Accurate taper control
  • Smooth inner surfaces finish
  • Minimized stress area around drilled holes

Different processing parameters might be developed upon request.

Ceramics drilling

Ceramics, due to unique available properties, is a leading material in communications and has been a top choice among many of our customers.

Applying our unique femtosecond laser capabilities, we employed our processing methods in order to offer market-leading services.

We are confident in offering hole diameters from a few micrometers to tens of millimeters at a very competitive price.

Features

  • No cracking of the material
  • Accurate taper control – positive, negative or zero taper
  • High aspect ratio
  • Possibility of drilling blind and through holes
