Laser marking
machine apply to PCB circuit board industry is often referred to as laser
engraving machine PCB or two-dimensional code laser engraving machine. In the
PCB industry, the advantages of laser marking technology embodied in the head,
two-dimensional code tag good quality, high efficiency, permanent markers, high
consistency, low cost, safety and reliability are widely used.
As the
development of technology, people's living standards continue to improve, smart
phone technology, wearable continuous development of electronic technology,
intelligence, light and thin, small order into the mainstream, consumers require
higher quality products, then as a manufacturer command quality control for
internal PCB circuit boards are increasingly stringent, we must do better in
order to win customers and win customer recognition, to achieve the second
purchase, such as Apple, Huawei and other technology leader.
So how to
achieve quality control of PCB, which need to use the product quality
traceability system. Usually means is used by laser marking, laser engraving
string on the PCB, one-dimensional codes, two-dimensional code and other
information uploaded to the database through the camera recognizes
automatically reject substandard products, and internal processes throughout
the product quality and traceability, supplier information from the source to
the product library data tracking, tracking, maximize the quality of the
product and the effective realization of the product automated production
control.
The string in
the early PCB surface, images, contact information, and other information are
used in two-dimensional code is a way to achieve an inkjet, but along with
consumers on product quality and improve, PCB manufacturers for PCB board
labeling accuracy is also increasing, as marked clearly visible, small format,
zoom no explosion point, bar code gun clear scale, contains extensive
information, etc., which has become a short board.
As electronic
devices, light and thin, miniaturization, PCB board format is very small, in
order to save the use of space, under normal circumstances, the two-dimensional
code marking on the PCB is very small, the size of two-dimensional code such as
2x2mm and it contains more than 20 characters of information, and some of his
products, such as photovoltaic silver TOP PCB board received two-dimensional
code to mark the smallest size of 0.8x0.8mm, mark this high-density, small
format two-dimensional code only laser marking technology can be achieved.
Laser marking
technology with respect to the ink jet method is more environmentally friendly,
economical and permanent marker will not be easily erased, non-destructive
non-contact marking, will not hurt the substrate, high precision, the minimum
can be achieved 0.12x0. 31 two-dimensional code laser marking 12mm, long life,
continuous work for more than 100,000 hours, faster processing efficiency, a
two-dimensional code in less than 1 second to complete, marking exquisite, hand
touch the top no touch, artificial simple, fool-processing.
Integrated laser
marking technology somewhat compared with the advantages and disadvantages of
the inkjet method, we can see that when a new generation of PCB-dimensional
code marking and laser technology is combined with a perfect partner. Laser
marking technology to help the PCB industry to complete the perfect quality
control, market-wide PCB board laser marking machine industry has provided a broad
space for development.
