…qualities that result
from a non-thermal ablation effect. On a
femtosecond time scale, material ablation
works similarly to vaporization by breaking
of chemical bonds, but without a melting
step. Peripheral areas of the ablation zone
are hardly affected because the…

…of sensitive materials, such as OLEDs, as well as "tough" materials, including
glass and ceramics. All that changes is the actual numeric values for ablation rate and fluence
(with the optimum ablation rates for more delicate materials occurring at lower absolute vales
for peak pulse…

…cut, laser scribing, ablation and non-thermal processes
such as filamentation. CO2 lasers provide the highest speed for
straight cuts with perfect edge quality.The non-thermal processing
of picosecond lasers come to play for ultra-thin glass, strengthened
glass or sapphire with…

…this. The first relates to the fact that every material has an ablation threshold (the minimum peak intensity required to vaporize and remove material) related to pulse duration. Reducing the pulse duration generally reduces the ablation threshold. This means that the required pulse energy decreases…

…any
glass type at speeds up to 2 m/s and glass
thicknesses up to 10 mm.
However, one limitation in some applications is that these picosecond systems
are not completely material neutral. Cutting mixed layer substrates, such as polyimide on glass and metal on glass, often

glass makes it easy to register
fiducial marks on one side of the glass when it
is flipped over for drilling from the second side.
Overall, this testing showed that vias down to
5 µm diameter could be successfully produced.
In addition, mask-based excimer laser ablation
