Laser marking on plastic electronic components by Maca ID
The electronic components industry uses a wide variety of plastics due to the varied functions required and the properties they provide. In general, plastics can be marked with fiber or DPSS lasers, the latter providing a better response for contrast generation.
However, each plastic poses its own difficulties that must be taken into account when marking, as there is no common marking solution for all materials. For example, the use of flame retardants in plastic processing or the doping of other materials such as fiberglass makes them more resistant and complicates colour change reactions for some wavelengths. If you also have to consider substrates of different colours, marking is often even more complicated.
In the case of this application, we have sockets in different colours and reactions to DPSS laser radiation. The best solution to obtain high contrast and high-quality marking is the use of a DPSS laser with a wavelength of 532 nm, corresponding to the colour green in the visible light spectrum. For this application, the D-5005-Green laser by Macsa id provides high-speed marking, with high definition and contrast applicable to all proposed colours, ensuring that the information is readable while preserving the integrity of the material.
