Laser marking is a clean, fast, non-contact process which relies on the intense heat of a focused laser beam to permanently modify the surface of the material being marked.
bleaching or changing the color of an additive in the material
physical modification of the surface finish
scribing a shallow groove by vaporization
controlled modification of the surface by melting
a combination of any of these processes
The type of marking is dependent on the characteristics of the laser. High peak power enables engraving,while the wavelength determines the type of Interaction with the material. Above 700 nm the interaction is mainly thermal. At lower wavelengths such as 532nm and 355nm of frequency doubled and tripled Nd:YAG lasers cause a photochemical reaction. Miyachi solutions allow the marking of alphanumeric characters, bar-codes, 2 DID Matrix, serial numbers, logos and graphics which are applied on metals, semiconductors, plastics, ceramics and other materials. Some applications require to have highly visible and attractive marks while other applications need marks on obscure places or require marks small enough to be only visible using magnification.
Clean environmentally friendly (no paints or additives)
Laser Marking Applications
Laser Marking can be achieved on almost all materials and is used on medical tools, PCB's, mobile phones, solar cells, semiconductors, etc.
