Question 1

What is ultrathin glass and how thin can it be?

Accepted Answer

Ultrathin glass refers to glass with a thickness below 0.3mm. MDI's cutting and laser solutions process ultrathin glass from as thin as 0.030mm (30µm) up to 0.2mm — thinner than a human hair.

Question 2

What is the minimum thickness MDI can process?

Accepted Answer

MDI's ultrathin glass solutions start at 0.030mm (30µm) for laser systems, and 0.010mm (10µm) using the SOLID-D® mechanical cutting tool. For reference, a standard sheet of office paper is approximately 100µm thick.

Question 3

What cutting methods are available for ultrathin glass?

Accepted Answer

MDI offers mechanical scribing and breaking using precision Penett® and APIO® cutting wheels, and laser cutting using green (532nm) or CO2 laser technology for contactless, dry, and highly precise cutting.

Question 4

Why is laser cutting preferred for very thin glass?

Accepted Answer

Laser cutting is completely contactless — no mechanical force is applied at any point. Additional advantages include no micro-cracks, dry process with no water or abrasives, suitability for cleanroom environments, and ability to cut complex shapes without retooling.

Question 5

What industries use ultrathin glass processing?

Accepted Answer

Ultrathin glass is used in consumer electronics, display technology (OLED, LCD, touch panels), semiconductor and microelectronics, medical devices, photovoltaics, automotive (HUD glass), and flexible electronics including foldable displays and flexible PV cells.

Question 6

Can ultrathin glass be processed in a cleanroom?

Accepted Answer

Yes. MDI's laser-based ultrathin glass processing is a dry, contactless, and particle-free process, fully compatible with cleanroom environments. MDI's CO2 laser systems feature integrated suction and no consumables that could introduce contamination.

Question 7

What edge quality can be achieved with ultrathin glass cutting?

Accepted Answer

With MDI's CO2 laser technology, ultrathin glass edges achieve optical quality with no subsurface micro-cracks. The SOLID-D® mechanical cutting tool achieves mirror-quality edges and a bending strength of 1GPa after cutting, enabling flexible and bendable glass.

Question 8

Can I test MDI's ultrathin glass processing before investing in a machine?

Accepted Answer

Yes. MDI operates a dedicated job shop where you can have your first batches of ultrathin glass processed without purchasing any equipment. Contact MDI at sales@mdi-ap.com to get started.
