Glass Carrier Wafers

Our ability to densely pack tens and hundreds of thousands of through holes in glass wafers allows us to offer price-effective carrier wafers for convenient handling and release processes.

We offer rapid prototyping and production services.

Depending on your needs we offer alkali and alkali-free perforated re-usable glass carriers which are custom-made according to your design.

A straight cross-section of the hole enables us to combine more holes than are possible with other technologies and combine large through-holes with narrow channels at the same time.

We ensure:

  • Ultra-high precision and quality
  • Various types of glass
  • Small feature sizes
  • High aspect ratios unachievable with alternative technologies
