Rigid-flex material
The LPKF MicroLine UV laser systems cleanly cut any circuit board material normally used for manufacturing circuits or parts. The combination of flex and rigid material is especially easy in one job. Registration problems and burr formation are eliminated.

Cutting of rigid PCB material
The LPKF MicroLine UV Laser systems are suitable for material thickness up to 1 mm (0.040 inch). Since LPKF uses a new generation of UV laser sources in combination with special designed laser optics, the burr formation is reduced to a minimum. The result is a precise cut with smooth, vertical edges.

Embedding chips
The LPKF MicroLine UV laser systems provide excellent pocket registration. Small pockets can be produced with virtually no radii in the edge floor to wall and with a depth tolerance of less than +/- 25 microns.

Structuring / repair of solder-resists
The LPKF MicroLine UV laser systems are suitable for the most ambitious opening of solder-resists in the HDI range <50 µm. Solder mask defects can be easily fixed by laser exposing of pads and traces.
