Combining the advantages of mechanical drilling of thick substrates including multilayers with extremely fast, contactless, laser surface processing. The laboratory system for processing FR4 as well as sensitive RF materials convinces with high performance. In its compact tabletop format, it can be used in any laboratory. The LPKF ProtoLaser Η4 enables efficient prototyping of complex digital and analog circuits, RF and microwave PCBs. The laser system achieves precise geometries on almost any material and is ideal for patterning single or double-sided PCBs, antennas, filters and many applications where precise steep edges are required.
