What is a LaserHow does a Laser Work

What Products are being MarkedWhy Laser marking is so Popular


3 Key Laser components

1. A laser source,- generates the laser beam.

2. A scan head,- deflects the laser beam via Glavo Controlled mirrors thru the Lens

3. The marking software,- Translates easy layout capabilities to laser pulses.


Software

How a laser marker works

− Laser marking is obtained by delivering and focusing a laser beam on the target surface by mean of motorized mirrors controlled by a dedicated software.


1. Laser source options

− Laser sources used today for marking span from 3 to 80 Watt of optical power while the most of the market belongs within the 10 to 30 Watt range.

− Laser technologies may from one producer to others, anyhow the main established ones are:

Different Wavelengths react with Different Materials− CO2 - 10,600nm− DPSS 1,064nm (diode pumped solid state)− Fiber 1,070nm− Green 532nm− UV 355nm


In addition to a laser source of suitable wave length, a marking laser requires three other mechano-optical components which are: the beam expander, the scanner head , and the flat-field focusing lens.

Lens

Laser Control Unit

Marking Control Unit/PC

A complete solution must include not only suitable laser emission controls, but also beam shot generation, and trajectory plotting control software.

Laser source: Q-switching effect

− Q-switching enables DPSSand Fiber lasers to reach very high peak power pulses, while CO2 lasers emits a continuous wave (CW).

CO2 10600

− Laser radiation is generated at different wavelength, depending on the laser source technology, from 180nm up to 10.6um. The most of the industrial applications belongs to the IR range.


Marking Software: User interface

− The software converts the graphics into vectors (parallel lines and paths) to be traced by moving the mirrors and switching the laser beam on and off accordingly.

− The software is used by the operator to define the marking layout by mean of a graphical user interface.

− Real-time control of the laser source and galvo head is then performed by the embedded software running on board the marking hardware.


Marking software: Optical correction

− The scanning head draws distorted shapes over the target surface because of barrel distortion effect, so, the software applies a correction algorithm in order to perfectly compensate.

DISTORTED IMAGE SOFTWARE CORRECTION MARKING RESULT


How laser process works

− The marking is realized by the portion of the laser radiation absorbed by the material. Nothing is added on the material surface, the laser changes how the material reflects the light.

Marking technique: Engraving

− The surface incision is made by rapid fusion and vaporization of the material with subsequent re-solidification of the edges of the groove. This effect is achieved by a combination of vaporization, melting and burning processes.


Marking technique: Ablation

− Anodic film, coatings or paint on metals and/or plastic can be easily vaporized without the need for high heat input, so, without affecting the underlying material.


Marking technique: Surface modification

− The material surface is altered by the inclusion of gas bubbles (foaming) or impurities. This effect is achieved by means of a controlled burning or melting process.


Marking technique: Color change

− Surface color change due to the oxidization on the metals (annealing), or photochemical reactions of the molecules of plastics (bleaching), and those of special color additives mixed into the plastics themselves.


Laser Integration and Safety

− Laser marking equipment is classified as a Class 4device, according to the IEC 60825 international standard.

− Laser integrators should implement all the relevant safety features in order to provide a Class 1 system to the end user.

− Safety Considerations− Line Of Sight Eye protection− Direct Touch Protection of digits− Burn Off Protection of Lungs/Nose


Off the Shelf Integration

Assembly Line IntegrationStand Alone Workstation.


Laser integration: Automated line

− Laser marking equipment is also installed onto fully

automated lines where it is requested to mark part

while moving.

− Together with safety features, the integrator should

implement the automated handling using the

appropriate encoder to deal with moving belt.


Why does the Laser Market continue its fast Growth?

− Salability – marking part numbers and logos on parts

− Liability – Limit liability from recall

− Traceability – Mark and Trace through production process

− FDA – New traceability regulations

− UID – Universal ID Datacode Marking for Military

− GREEN TECHNOLOGY-No toxic inks, additives or waste

Customer Request…

Hospitals and medical environments in general, in addition to demanding accuracy in non-disposable tools cleaning, look for traceability methods to manage huge amounts of tools. Datamatrix codes can solve this issue, but marking must not involve any modifications of the metal surface. Also, the marking system must fit strict space requirements, looking for small footprint in hospital technical departments.

…DLA’s Solution

DLA’s Ulyxe 6W infrared laser marker can easily fit into small marking equipment, and its 1064 nm wavelength achieves high-contrast 2D marking on tools surface, making them easily readable despite metal reflection.

Customer Request…

The customer requested a laser marking solution able to grant effective traceability of car window glasses (floating glass) by using datamatrix codes. Perfect readability of the code through the entire production process (including temper), together with unaffected mechanical properties of the glass, are fundamental requirements. The customer asked us to find the best solution choosing among a CO2 laser, a green laser and an UV laser. The maximum amount of marking time was 5 seconds.

…DLA’s Solution

DLA’s UV-Lase was found to be the best marking solution to meet the customer requirements. Unlike infrared and green light, UV light marks the datamatrix inside the glass, thus making it permanent through all the following treatments. Moreover, the glass does not lose its mechanical characteristics (e.g. resistance to tensile stress).

Customer Request…

Traceability through datamatrix codes, alphanumerical codes, or both, is highly recommended in solar cells glass substrate production. But laser marking on one side of the panel might affect also its opposite side, where a very thin TIN coating is applied. Thus accurate and selective laser marking is required.

…DLA’s Solution

When DLA’s UV-Lase laser marker is adjusted to focus on the uncoated side, there is no effect on the opposite side of the thin glass substrate. Since traceability marking requires small sizes, a marking speed between 50 mm/s and 150 mm/s provides high throughput, depending on fonts and graphics.

Customer Request…

A new soldering process to replace manual positioning and oven-welding.Copper Top-pin or Pack-pin covered with a silver-tin alloy must be soldered on a DBC substrates (Direct Bond Copper), composed of a ceramic insulator, Al2O3 onto which pure copper metal is attached by a high temperature eutectic melting process and thus tightly and firmly joined to the ceramic.DBC High thermal conductivity prevents any contact based soldering techniques.

…DLA’s Solution

DLA’s KUBO 100 laser welding system can quickly and easily solder the pins because the high peck power overcomes the thermal conductivity effects.

KUBO 100 , 100W @ 1064 nm
