Green Lasers Allow Finer Structures

New precSYS 515 micromachining subsystem for electronics fabrication

Leading OEM scan solution manufacturer SCANLAB GmbH is presenting a new member of its precSYS product line at the LASER World of PHOTONICS 2019 tradeshow in Munich, Germany. Five-axis precSYS subsystems enable industrial ultra-short-pulse (USP) laser micromachining of flexible, definable geometries with high aspect ratios. The availability of a subsystem optimized for 515-nm lasers is particularly attractive in the electronics industry, where it allows creating probe cards with even finer lateral structures. Ongoing technological advances in the consumer electronics and mechanical engineering sectors bring
countless changes to how electronic components such as PCBs, control elements and sensors are made. Here, a relatively new laser processing market is the production of probe cards for testing integrated circuits. These probe cards place the highest demands on laser micromachining systems used in micro-structuring applications.
To even better address such demands, SCANLAB is extending its precSYS product line with a subsystem optimized for 515-nm green lasers. That’s exactly half the applied wavelength of a 1030-nm infrared laser, which leads to a much smaller spot size and enhanced lateral precision in processing challenging materials. At the same beam
aperture angle, a larger aspect ratio is achievable.
All precSYS scan solutions are galvo-based 5-axis subsystems for integration into laser machines. Thanks to their flexible laser beam positioning capabilities (in the x, y, z, α and β directions), these scan heads offer the highest freedom in developing new process
strategies. Circular, elliptical or linear trajectories can be defined for processing in 2D or 3D.
Effective immediately, the entire product line has received a servo control strategy update that enables even higher rotational frequencies and processing speeds in drilling operations. The new DrillControl software version supports both versions of precSYS and allows to use also existing laser jobs. Initial precSYS 515 systems will be orderable
as of Q4 2019.
