The technology has the potential to preserve data inside glass for millions of years without decaying
The PEARL M-UTG is used for cutting of ultra-thin flexible glass. The system is integrated in a fully automated processing line and enables the cutting of glass foils as thin as 30 µm
The new laser is ideal for structuring and ablating thin films in displays and photovoltaics, trimming of micro-resistors and capacitors, and high-contrast marking of medical devices, plastics and glass.
Ultra-thin glass is now being used in the flexible displays of foldable smartphones.
Ultra-thin glass offers exciting opportunities but poses exceptional manufacturing challenges, Matthew Dale finds
For some years now, laser cutting processes based on filament technology with ultra-short pulse (USP) lasers have been increasingly adopted in industrial applications.
The main reasons for this are the good edge quality that can be achieved with simultaneous easy automation and free-form capability. This ability to be automated is of critical importance, especially for applications that target the mass market with their end products.
However, the real advantage of the technology comes from its almost unlimited free-form capability. In addition to established manufacturing processes for glasses of medium thickness from 0.2-2 mm, an increasing number of applications with ultra-thin glasses of 30-100μm are entering the market. These applications also require further development of the process and fab technology.
