Example of processing a Φ40μm through hole in alumina.
This is an example of through-hole processing in alumina using a Φ40μm laser.
A multi-hole through processing with a diameter of 0.05 mm and a pitch of 0.5 mm was performed on a tantalum foil with a thickness of 0.05 mm.
In general, machining tantalum is difficult or time-consuming for fine processing, but our company has made it possible to achieve burr-free and highly round fine hole processing through laser machining.
This is an example of gradient processing on PET with a minimum width of 20μm to 100μm. Depth control is possible up to 0.5μm.
In laser processing, controlling the depth is difficult, and issues such as dross and smear caused by thermal effects occur, leading to irregular shapes in fine processing. Our company has solved these drawbacks of laser technology.
A dot shape was processed on SUS430J1L with a size of approximately 300nm.
During the experiment on nano-periodic structure (LIPSS) processing using femtosecond lasers, a lattice-shaped LIPSS structure appeared instead of the previously introduced linear LIPSS shape!
