LPKF PROTOLASER U4
The ProtoLaser U4 is a valuable tool in the electronics laboratory. The compact laser system produces precise, fine structures for demanding PCBs in a very short time – as single pieces or small series, without masks or tools.
Product Desription
LPKF ProtoLaser U4 uses a scanner-guided laser with a wavelength of 355 nm in the UV spectrum. This wavelength makes it possible for many material groups to be perfectly processed with the laser without additional tools, masks or films. Placing scan fields next to each other results in a working range of up to 229 mm x 305 mm x 10 mm. The laser focus with a diameter of approx. 20 µm allows for structures with a pitch of 65 µm (50 µm line width, 15µm apart) related to FR4 with 18 µm Cu. This laser system is stable in the lower power range so that even thin and organic layers can be processed with minimal heat transfer.
The system also includes a rapid vision system for laser micro material processing and for detecting fiducials and geometric structures on the substrate.
Product Highlights
UV laser source as a versatile tool
Stabilization in Low-energy Range
Intricate, sensitive processes require an extremely low laser energy level. The new UV laser source has been designed accordingly and is stable over a large range of energies. This is especially beneficial for applications with thin films or delicate materials.
Process Tracking
An integrated power meter determines the actual laser power in the focus position. This yields precise actual data for documentation of the production process.
Vision System
The LPKF ProtoLaser U4 uses a newly designed rapid vision system that has been optimized for laser micro material processing. Fiducials and geometric structures on the substrate can be detected.
