Electronics - Component Marking
Laser technology provides one of the most reliable methods of direct part marking and can easily achieve high contrast details enabling traceability of almost any product.
The clean, high quality, permanent marks obtained with a laser are durable enough to withstand harsh environments, including cleaning with disinfectants and steam sterilisation.
Since the laser can accurately engrave characters as small as 0.015", it can be used where there would be no room for other marking methods. Indelible laser marking for security is emerging as the method of choice for tracing such items as pharmaceuticals, CD-ROMs and other hand goods that are subject to copyright and trademark piracy.
Since laser engraving is a non-contact process, it can be used to mark parts that would be damaged by impact and vibratory marking methods. Laser beams can reach down to the bottom of blind pockets, into grooves, into the inside bottom of bottles, and other places that only a non-contact beam could reach.
Laser marking can be used on materials where a lack of part distortion is critical such as ball bearing surfaces. In these cases, the mark can be as little as 0.0001" deep if required.
The electronics industry requires high volume permanent laser marks on its components without physical or thermal stresses induced. The wavelength of the laser can be tailored to the device material to produce high absorption and little heat during the marking process. The processing speed oflaser marking is also much higher than conventional marking methods.
