With the increase in functionality of electronic equipment products, the miniaturization and thinning of components have become increasingly high, and it is necessary to engrave extremely small characters in a limited space and reduce marking damage. Take the miniaturization of the package as an example, its area ratio has been reduced to 1/10 of the previous.
And with the increasing sales of ultra-thin communication devices such as smartphones and tablet computers in recent years, the development of high-quality products and efficient manufacturing processes, the traceability range is not only the final product, but also its constituent parts. .
The characteristics of UV lasers are: Compared with traditional lasers, it can suppress damage to products and use very small spots for fine marking.
Advantages of UV laser marking 1-reduce product damage
Advantages of UV laser marking 2-fine marking
The spot diameter of the laser is greatly affected by the wavelength of the light. The UV wavelength (355 nm) is 1/3 of the basic wavelength (1064 nm), so the spot size can be reduced and marking can be performed in a limited space.
