The ProtoLaser U3 is an ultraviolet laser system with a 20 µm focused beam diameter for processing printed circuit boards. Winner of a SMT Vision Award, the ProtoLaser U3 can etch circuitry, drill holes, and depanel PCBs all in a single step.
The system works straight from CAD data to process boards with laser paths generated within LPKF CircuitPro software. Circuit traces as small as 75 µm (3 mil) can be achieved with laminated PCB materials and 50 µm traces with spacing of ~20 µm with Alumina/fired ceramics. Smaller features may be possible and results are dependent on copper/metal thickness, substrate type and peel strength. The system's advanced speed allows it to be used not only for R&D but also on-demand production.
Thanks to the high photon energy and low-stress nature of UV lasers, the ProtoLaser U3 can laser etch, drill and cut a wide variety of PC board substrates: FR4, fired ceramics, green and co-fired LTCC, flexible and rigid-flex materials, transparent conductive oxide (TCO), PET, and high-frequency RF and microwave materials (Rogers TMM®, RT/duroid®, RO4000® series, etc.).
