ProtoLaser U4

Micromachining with the LPKF ProtoLaser U4

The LPKF ProtoLaser U4 builds on our wealth of experience with a wide range of applications and opens up an even wider process window than its predecessors.

UV laser source as a versatile tool

The LPKF ProtoLaser U4 uses a scanner-guided laser with a wavelength of 355 nm in the UV spectrum, that has been specially developed for use in electronics laboratories. 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.

Powerful system software

The user-friendly LPKF CircuitPro PL system software gives access to all important process parameters. A comprehensive parameter library that not only includes many common but also exotic materials provides assistance for the operator's own projects.

Stabilization in the low-energy range

Fine, sensitive processes require very little laser energy. The new UV laser source is designed accordingly and is stable over a wide power range. This benefits applications with particularly thin layers or delicate materials.

Process Tracking

A power measuring field determines the actual power of the laser when in focus position. This results in accurate actual data for documenting the production process.

Vision system

The LPKF ProtoLaser U4 uses a newly designed, fast vision system optimized for laser micromachining. The camera and the image recognition process capture fiducials or geometric structures on the substrate to be processed.

LPKF ProtoLaser Overview

Thanks to the specific wavelength of the UV laser, the ProtoLaser U4 can structure, engrave and cut materials in a single operation. This laser system is stable in the lower power range so that even thin and organic layers can be processed with minimal heat transfer.

ProtoLaser R4 -- picosecond laser

Laser ablation with practically no heat transfer: The shorter the processing pulse, the less heat is transferred to the adjacent material. The picosecond laser of the ProtoLaser R4 clears - an important hurdle falls: There is no more heat transfer to speak of, with the material struck by the laser evaporating right away.

The compact laser system produces precise, fine structures for demanding PCBs in a very short time. Using a special process, the ProtoLaser S4 quickly removes large copper areas from laminated substrates such as FR4. The ProtoLaser S4 also delivers excellent results on special materials for RF applications.

The LPKF ProtoLaser ST tabletop laser system enables efficient prototyping of complex digital and analog circuits, RF and microwave circuit boards. The system achieves exact geometries on almost any material and is ideal for structuring single or double sided circuit boards.
