The LPKF ProtoLaser S4 features the new LPKF design, combining a classy look with clever solutions for operation and maintenance. Integration of the control PC is optional.
The ProtoLaser S4 is a valuable tool in the electronics lab. It can quickly and accurately generate fine structures and uses a special procedure for ablating large areas. The laser process requires no masks or tools to produce one-offs or individual marks.
Switching to a green laser wavelength increases the range of applications. A green laser is much less likely to burn the substrate. It can also reliably machine inhomogeneous metal layers with up to 6 μm variance in Cu thickness - e. g., boards with fully metallized surfaces following galvanic via plating. The ProtoLaser S4 can cut and drill rigid or flexible substrates efficiently with thicknesses of up to ~1mm; thicker materials also allow drilling/cutting with additional laser passes.
The LPKF ProtoLaser S4 has a newly designed fiducial recognition camera and image processing system that has been optimized for circuit board prototyping. A higher resolution and faster detection algorithms accelerate the manufacturing process. This camera allows the LPKF ProtoLaser S4 to visually inspect and properly align the workpiece.
The LPKF ProtoLaser S4 laser system can laser etch PCBs in minutes on a wide range of laminated substrates, FR4 and PTFE or woven PCB materials. Prototypes and small production batches can also be produced on short notice if required. The system requires no chemicals and is easy to operate with LPKF CircuitPro software included.
The LPKF ProtoLaser S4 is even more precise than the mechanical systems and is therefore ideal for HF and microwave circuits, as well as digital and analog circuits. It produces precise geometries on a whole range of substrates such as copper-clad FR4, aluminum-coated PET films, ceramics, Duroid and PTFE.
Alignment for two-sided prototypes increases tremendously with the fiducial recognition camera. This camera allows the LPKF ProtoLaser S4 to visually inspect and properly align the workpiece.
For drilling through-holes in thicker printed circuit boards and for multilayer applications, an LPKF ProtoMat is a perfect complement to a LPKF ProtoLaser S4.
