LASER DEPANELING

Laser cutting PCBs: The technology behind our depaneling machines

Laser Depaneling is the most innovative and promising technique for cutting and separating printed circuit boards from the panel and is differentiated from the classic separation methods in particular by its flexibility and stress-free processing.

What is (Laser-)Depaneling?

Laser Depaneling is one of the most modern and promising processes for separation PCBs from the overall panel. During the depaneling process, the previously manufactured and assembled printed circuit boards (PCBs) are cut out of the panel using a suitable separation process/tool. In the case of laser depaneling, the singulation process is performed by a focused laser beam that ablates the material layer by layer. The laser method - especially applied by LPKF machines - offers significant advantages compared to conventional mechanical separation methods.

Laser cutting PCBs: How does the process work?

In case of laser depaneling, the thermal energy of the laser is used to remove the material path by path / layer by layer. With each repitition, a pre-defined thickness of the material is ablated and vaporised. The resulting fumes are extracted during the process by a powerful suction system. Due to the small particles and the powerful suction, the deposition of residues is reduced to a minimum. In addition, the thermal energy is regulated during the entire process in such a way that, depending on the specific requirements, there is no or only very little carbonisation of the material.

Due to the layer-by-layer ablation process of the laser, it is not only possible to cut through the boards completely, but also to remove individual layers or predefined thicknesses of the material. Due to the precision and filigree of the laser, ablations can be performed with an accuracy of a few µm.
