Markings as Small as a Grain of Sand

The miniaturization of the printed circuit board with simultaneous high assembly density increases the requirement to apply codes in the smallest possible space. ASYS has the answer: the laser marking system INSIGNUM 6000 uses a CO2 laser and a positioning accuracy of +/-100μm@5Sigma to mark codes smaller than 1mm. Therefore module sizes of <3mil (0.08mm) are possible.

A product becomes a unique specimen by providing it with a unique code. Traceability is the big keyword here.In times of electromobility and 5G technology, high performance electronics are applied to a smaller PCB area. Accordingly, the markings must also shrink. This requires a new type of technology in the field of laser marking.

The ASYS laser experts have taken up the challenge. They have succeeded in guiding the laser beam through optics in such a way that a small spot is created with which 3mil codes can be generated. This technology is integrated in the new laser marking system INSIGNUM 6000 3mil. The system uses a CO2 laser and a positioning accuracy of +/-100μm@5Sigma to mark codes smaller than 1mm. Therefore module sizes of <3mil (0,08mm) are possible.


  • Miniature Markings: Codes smaller than 1mm with module sizes <3mil
  • High-Precision Marking: Markings with a positioning accuracy of ±100μm @ 5 sigma
  • Flexible: Different laser sources can be integrated


Flexible Platform - Configure the Machine to Your Needs

With the flexible laser platform INSIGNUM 6000 it is possible to realize any requirements in the field of laser marking. In addition to the realization of module sizes smaller than 3mil, model variants for double-track solutions, the processing of large format printed circuit boards and the marking of e.g. ceramics, plastics and DBC substrates are also possible. Transport system and laser types are individually adapted to the process requirements. Different laser sources such as CO2, fiber, green and UV can be used in the system to meet any special requirements. In the basic version, the plant is equipped with a 10 Watt CO2 laser, X/Y linear axis and transport system.

Marking in the Life Sience Sector

Especially in the life science sector, there is a clear trend towards smaller components. These include category III medical technology products such as implants for cardiology or sensor technology for monitoring vital body parameters such as blood sugar, blood pressure and blood gas. With the simultaneous introduction of MDR (Medical Device Regulation), smaller 2D codes are becoming necessary for the traceability of components.

Did You Know?

More than 1,500 codes with module sizes <3mil fit on a single stamp.
