Efficient Use of PCBs: New Possibilities thanks to CleanCut Technology

The new Managing Director ElectronicsQuipment, Benjamin Klingen-berg, has only been in his new position at LPKF Laser & Electronics since October. However, he is far from unfamiliar with the company as he was employed at the headquarters in Garbsen from 2000 to 2009. Now, after nine years, he has returned - and is convinced of the many new developments and innovative technologies. He was particularly impressed by the CleanCut technology, which sets a new standard for fast and clean PCB depaneling using lasers.

"Laser technology has numerous advantages over mechanical cutting processes when it comes to PCB processing and particularly depaneling: extremely low material stress due to quasi contact-free cutting, minimal edges to the cutting areas, no milling dust, largely free geometries and flexible design due to digital data processing. In industrial applications, where minimum size, maximum functional density and high cutting quality without chipping are required for printed circuit boards, laser technology is a must.

LPKF has achieved a further breakthrough with its innovative CleanCut technology and has significantly improved speed and cleanliness which are the two most important parameters for depaneling. The use of Clean-Cut avoids any discoloration at the cutting edges that can occur during conventional laser processing. In addition, laser processing speeds of previously unknown dimensions can be achieved. This is groundbreaking in the field of depaneling and offers both PCB manufacturers and EMS service providers an unprecedented degree of efficiency with the highest cutting quality - and thus also new possibilities for PCB design.

At electronica, we will present this technology live for the first time with our PicoLine 3000 ci laser system, which was specially developed for integration into fully automated production lines at EMS service providers. High quality printed circuit boards are processed with this system in a very gentle way.
The user can now build even more compact and utilize printed circuit board surfaces up to the edges. Thanks to software-defined cutting paths and extensive geometrical freedom, it is possible to work out de-velopments faster and more flexibly - and to implement new geometries.
The results improve the reliability of the subsequent circuits. The process safety ensures that the printed circuit boards also meet the high-quality requirements of the automotive industry and medical technology.

The fact that additional cleaning processes after laser cutting are super-fluous offers considerable savings in terms of process flow and material costs.
I think LPKF's PicoLine systems have opened up great opportunities for PCB production and depanelization at the end of the assembly lines and offer new options for various fields of technology".
