Laser engraving pcb board is a kind of efficient and precise printed circuit board processing equipment, which adopts the laser technology, can carry out high-precision engraving, laser engraving, etc. on the surface of PCB, so as to realize the marking, marking, layout, cutting and other processing of the circuit board, which provides important technical support for the production of circuit boards.
Laser marking is the use of high energy density laser on the PCB substrate for local irradiation, so that the surface material vaporization or discoloration, thus leaving a lasting mark. This kind of non-contact processing, can be in a very small amplitude marking out very clear two-dimensional code, to ensure high precision at the same time to ensure high quality. At the same time, the laser marking will not wear out due to high and low temperatures, changes in acidity and alkalinity, and external friction, and does not require the assistance of chemicals, so there is no negative effect on personnel safety and the environment.
In the pcb board laser marking lettering application, the use of more UV laser marking and CO2 laser marking. UV laser marking and CO2 laser marking have become the technology of choice for surface marking of PCB boards due to their low thermal impact, good processing results, high precision and speed.
A large number of printed circuit boards can also be operated using fully automated laser marking machine, only need to install automated flow part on the UV laser marking machine and CO2 laser marking machine to realize the automatic loading and unloading of PCB boards, to facilitate the circuit boards directly for marking and processing, without the need to transport to the marking and processing of the unified processing of the place, to improve the marking efficiency, to improve the processing of the coherence of a circuit board laser marking machine. Greatly improve the efficiency and cost savings.
Advantages
- good quality, wear resistance, circuit board surface marking clear and beautiful, can be labeled with a variety of LOGO, pattern, two dimensional code, text, and the pattern is engraved directly on the material above, wear resistance is more prominent;
- High processing precision. Laser beam emitted by the laser is focused after the minimum spot diameter can reach 10um (UV laser), in dealing with complex graphics and precision processing with a small big help;
- High efficiency, simple operation and cost reduction. Users only need to set up the parameters on the computer can directly marking, in just a few seconds to a dozen seconds to complete the material surface marking.
- Non-destructive marking. Laser marking using non-contact processing, the laser head does not need to contact the surface of the material, so do not need to consider the damage to the material;
- Wide range of use, safety and environmental protection. All kinds of thin metal/non-metal materials can be marked;
- Stable performance, long service life of the equipment. With the development of technology, the service life of the laser is greatly increased, and the service life of the equipment is greatly lengthened.
